Auto Insurance Glossary

Texas auto is a contract. Here is the language inside it.

Fifty-five Texas auto insurance terms defined plainly. Texas minimum limits, A.D.D., Agreed Value, UM/UIM, OEM parts, Texas Insurance Code Section 1952.301, comparative fault, and the rest of the vocabulary every Houston household with vehicles should understand before signing the next renewal.

Texas Minimum Limits
What is auto insurance terminology and why does it matter for Houston households?

Texas auto is a contract. The vocabulary decides what gets paid.

Texas auto insurance is a contract built from defined terms that decide what gets paid, when, and how much. Minimum limits of 30/60/25 are the legal floor under Texas Transportation Code Section 601.072, but they are inadequate for most modern accident scenarios. UM/UIM coverage protects against the approximately 20 percent of Texas drivers who carry no insurance and the many more who carry only minimum limits. Section 1952.301 of the Texas Insurance Code governs labor rate reimbursement when your vehicle is in the body shop. Most Texas households sign their auto policy without understanding the language inside it. The McDade Auto Insurance Glossary defines 55 Texas auto terms in plain English so you can read your declarations page line by line. Every definition is written for Houston households with the specific context of the Texas Insurance Code, Texas Department of Insurance rules, Texas DMV requirements, Texas court precedent on comparative fault and material misrepresentation, and the policy form differences we see across the Texas auto market.

A

Actual Cash Value (ACV)

The settlement basis most auto policies use for total loss and physical damage claims. ACV is the vehicle's replacement cost minus depreciation at the time of loss, reflecting current market value rather than purchase price or remaining loan balance. ACV typically comes from third-party valuation services (Mitchell, CCC, Audatex) using regional comparable-sale data.

Why It MattersA Houston household that financed a vehicle for 60 months and totals it in year three frequently discovers the ACV settlement is several thousand dollars below the loan payoff. TDI consumer materials note the ACV-versus-loan-balance gap as the primary use case for gap insurance. ACV disputes are among the most common Texas auto claim complaints filed with TDI.
Charles in Plain EnglishToday's value, not yesterday's price. Settlement starts where the depreciation ends.

SourceTexas Department of Insurance, Auto Total Loss Guide

Additional Driver Discovery (A.D.D.)

A carrier underwriting practice where the carrier discovers undisclosed drivers in the household through public records, social media, license-plate scanning, and credit-bureau cohabitation data, then adds those drivers to the policy and bills retroactively or at renewal. Progressive and several other Texas-active carriers run A.D.D. on a regular basis.

Why It MattersHouston households frequently exclude an adult child living at home, a roommate, or a domestic partner from the auto application to keep premium low. A.D.D. discovers the omission, often months later, and produces a premium recalculation that can include back-billing. The Texas Department of Insurance has issued consumer alerts about A.D.D. practice and recommends households disclose every regular driver at policy issue to avoid mid-term repricing.
Charles in Plain EnglishThe carrier already knows who lives at your address. The question is whether your policy does too.

SourceTexas Department of Insurance, Auto Insurance Guide

Adjuster

The person assigned to evaluate, negotiate, and settle the auto claim. Texas recognizes three categories: company adjusters employed by the carrier, independent adjusters working under contract to the carrier, and public adjusters hired and paid by the policyholder. Public adjusters in Texas are licensed by the Texas Department of Insurance and operate under specific fee and disclosure rules.

Why It MattersThe adjuster the policyholder meets is the carrier's adjuster. A Houston household with a significant total loss, contested liability, or repair-versus-total dispute can hire a Texas-licensed public adjuster to negotiate independently. The Texas Department of Insurance maintains a roster of licensed Texas public adjusters and publishes the fee disclosure rules that govern their compensation.
Charles in Plain EnglishThe adjuster works for the carrier. Texas lets you hire your own.

SourceTexas Department of Insurance, Public Adjuster Information

Aftermarket Parts

Replacement parts manufactured by a company other than the original vehicle manufacturer, typically used by carriers to reduce repair costs. Aftermarket parts include sheet metal, lights, bumpers, and some structural components. Texas Insurance Code requires carriers to disclose the use of aftermarket parts on the repair estimate and to certify that the parts are of like kind and quality to OEM.

Why It MattersHouston body-shop disputes frequently involve aftermarket-versus-OEM parts decisions. TDI consumer materials reference the disclosure requirement and explain that policyholders may have the right to insist on OEM in many circumstances. The John Eagle Collision Center case in Texas highlighted structural-repair quality concerns when aftermarket parts are used in collision-critical areas.
Charles in Plain EnglishOEM came on the car. Aftermarket comes in the repair.

SourceTexas Department of Insurance, Auto Parts Disclosure Rules

Agreed Value

A settlement basis where the carrier and policyholder mutually agree on the vehicle's insured value at policy issue, and that agreed amount is paid in the event of total loss regardless of market depreciation. Agreed Value is the dominant rating for classic, collector, antique, and exotic vehicles. Specialty carriers writing Agreed Value in Texas include Hagerty, Grundy, and American Modern.

Why It MattersA Houston collector with a restored 1965 Mustang under a mass-market auto policy receives ACV at total loss, often far below the actual market value of a restored example. An Agreed Value policy from Hagerty, Grundy, or American Modern pays the agreed amount, sometimes with appreciation factors built in. TDI consumer materials encourage collector-vehicle owners to consider specialty carriers offering Agreed Value.
Charles in Plain EnglishStated Value sounds like a promise. Agreed Value is one.

Antique Vehicle

A vehicle that meets specific age and use criteria for specialty auto insurance, typically 25 years or older, maintained primarily for collector use rather than daily driving, garaged when not in use, and driven under a stated annual mileage cap (commonly 2,500 to 7,500 miles per year). Texas DMV recognizes specific antique vehicle registration categories.

Why It MattersHouston collectors who insure antique vehicles on standard daily-driver policies overpay on premium and underinsure on settlement at total loss. Hagerty, Grundy, and American Modern offer Texas antique vehicle policies with Agreed Value, lower premium reflecting limited annual mileage, and broader collector-vehicle coverage (spare parts, automobilia, attendance at car shows). TDI consumer materials recommend specialty placement for any vehicle meeting antique criteria.
Charles in Plain EnglishAntique policies use Agreed Value. Mass-market policies use ACV.

SourceTexas DMV, Antique and Classic Vehicle Registration

At-Fault Accident

An accident where the policyholder is determined to be the legally responsible party for causing the collision. Texas law uses the police accident report, witness statements, physical evidence, and applicable Transportation Code provisions to assign fault. An at-fault designation typically results in liability and physical damage coverage on the at-fault driver's policy paying the other party's losses.

Why It MattersTexas operates under modified comparative fault, so an at-fault designation is not always binary. A driver found 30 percent at fault still recovers 70 percent of damages from the more-at-fault party. Houston accident reports frequently produce comparative-fault assignments that drive complex multi-party settlements. TDI consumer materials encourage households disputing fault assignments to use the local law-enforcement supplemental report process.
Charles in Plain EnglishAt-fault is the police report. Comparative fault decides what gets paid.

SourceTexas Department of Insurance, Auto Claim Process

B

Bodily Injury Liability

The auto liability coverage that pays for physical injury, sickness, disease, or death suffered by other people when the policyholder is legally responsible. Texas minimum bodily injury liability is 30,000 dollars per person and 60,000 dollars per accident (the 30 and 60 in 30/60/25). Higher limits are typically 100/300, 250/500, or 500/1,000 expressed in thousands.

Why It MattersA serious Houston freeway accident with multiple injured passengers can produce demands well above the 30/60 minimum. TDI consumer materials recommend households evaluate bodily injury limits against household net worth, particularly when an umbrella policy is in force (because the umbrella requires minimum underlying limits typically of 250 or 500 thousand dollars).
Charles in Plain EnglishBI pays for the person you hit. PD pays for the thing you hit.

SourceTexas Department of Insurance, Auto Liability Limits

Bundling

The practice of buying multiple policies (home, auto, umbrella) from the same carrier to receive a multi-policy discount on each policy in the bundle. Bundling discounts typically run 5 to 25 percent depending on the carrier and the specific policy combination. Bundling can simplify billing, claim handling across products, and renewal review.

Why It MattersHouston households frequently bundle for the discount without comparing whether the bundled package is the best per-product contract. A carrier with a competitive auto policy may have a non-competitive home policy. TDI consumer materials recommend households evaluate the contract on each policy independently, then evaluate whether bundling makes financial sense. About 40 percent of the time the right answer is to bundle. The other 60 percent benefits from product-by-product placement.
Charles in Plain EnglishBundling earns a discount. It does not earn the right policy.

C

Cancellation

The termination of an auto policy mid-term by the carrier or the policyholder. Texas carriers can cancel for limited specific reasons during the first 60 days (broad discretion), and only for narrower reasons after 60 days (non-payment, material misrepresentation, license suspension, fraud). Cancellation requires written notice with statutorily specified notice periods.

Why It MattersA Houston household notified of mid-term cancellation has specific rights under Texas Insurance Code, including the right to a written reason and the right to dispute through the Texas Department of Insurance complaint process. TDI market and complaint materials track Texas cancellation complaints. Cancellation history affects future rate offers and can produce non-standard market placement.
Charles in Plain EnglishTexas requires written notice. Most carriers send it certified.

SourceTexas Department of Insurance, Cancellation Rules

Claim

A request for payment under the auto policy following a covered loss. Texas auto claims follow a defined timeline: notice of loss, acknowledgment, investigation, coverage determination, settlement offer or denial. Texas Insurance Code specifies maximum timeframes for each step. The claim file becomes the basis for any subsequent dispute or litigation.

Why It MattersA Houston household filing an auto claim should document the loss, retain repair estimates, keep all communication with the adjuster in writing, and confirm coverage determinations before authorizing repairs. TDI consumer materials recommend written confirmation of coverage decisions and provide a Texas auto claim timeline guide. Filing a claim may affect future renewal rates depending on the carrier and circumstance.
Charles in Plain EnglishThe claim is the contract in motion. Everything before was paperwork.

SourceTexas Department of Insurance, Auto Claim Process

Collision Coverage

The auto coverage that pays for physical damage to the insured vehicle caused by impact with another vehicle, an object (tree, mailbox, guardrail), or by rolling over. Collision coverage is subject to a deductible (typically 250 to 1,000 dollars) and is required by lenders on financed vehicles. Collision is paired with comprehensive coverage to make up what most consumers call full coverage.

Why It MattersHouston households driving in heavy I-10, US-59, or Beltway 8 traffic face elevated collision exposure. TDI consumer materials recommend collision coverage on financed vehicles and on owned vehicles with significant ACV. Collision premium scales with the vehicle's value, the chosen deductible, and the driver's loss history.
Charles in Plain EnglishCollision pays when you hit something. Comprehensive pays when something hits you.

SourceTexas Department of Insurance, Auto Physical Damage Coverage

Comparative Fault (Texas Modified)

The Texas rule for allocating responsibility when multiple parties contributed to an accident. Texas operates under modified comparative fault with a 51 percent bar. A plaintiff who is 50 percent or less at fault recovers reduced damages. A plaintiff who is 51 percent or more at fault recovers nothing. The rule is codified in Texas Civil Practice and Remedies Code Chapter 33.

Why It MattersHouston multi-vehicle accidents frequently produce comparative-fault assignments that change settlement amounts dramatically. A driver 30 percent at fault who would otherwise recover 100,000 dollars instead recovers 70,000 dollars. A driver 51 percent at fault recovers zero from the other parties. TDI consumer materials encourage households disputing fault percentages to consult with a Texas personal-injury attorney before settlement.
Charles in Plain EnglishTexas pays you if you are 50 percent or less at fault. 51 percent pays you nothing.

SourceTexas Civil Practice and Remedies Code Chapter 33

Comprehensive Coverage

The auto coverage that pays for physical damage to the insured vehicle caused by non-collision events including hail, fire, theft, vandalism, falling objects, animal strikes, glass breakage, and flood. Comprehensive coverage is subject to a deductible (typically 250 to 1,000 dollars). Glass breakage is often subject to a separate, often zero, deductible.

Why It MattersHouston is in one of the most active hail markets in the country. The Cypress 77433 corridor, parts of Spring, Klein, and the Katy I-10 corridor regularly produce hail claims sufficient to declare a vehicle total loss. TDI consumer materials recommend comprehensive coverage on vehicles parked outside in hail-prone areas. Hurricane Beryl wind damage in 2024 also produced significant comprehensive auto claims.
Charles in Plain EnglishHail, theft, falling tree, deer. Comprehensive pays for what driving did not cause.

SourceTexas Department of Insurance, Auto Physical Damage Coverage

D

Declarations Page (Dec Page)

The summary front page of the auto policy that identifies the named insured, the covered vehicles by VIN, the coverages selected, the limits and deductibles, the premium, the policy effective and expiration dates, the named drivers, and any specific endorsements in force. The dec page is the most important single document in any auto policy review.

Why It MattersA Houston household renewal review begins and ends with the dec page. Two dec pages side by side reveal coverage differences, limit differences, deductible differences, and endorsement differences. TDI consumer materials recommend households review the dec page at every renewal cycle. Most coverage misunderstandings are visible on the dec page if the policyholder reads it line by line.
Charles in Plain EnglishTwo dec pages, side by side. That is what a renewal review looks like.

SourceTexas Department of Insurance, Understanding Your Auto Policy

Deductible

The amount the policyholder pays out of pocket before auto coverage begins paying. Deductibles typically apply to collision and comprehensive coverage separately, with common amounts of 250, 500, 1,000, or 2,500 dollars. Higher deductibles produce lower premiums. The deductible applies per claim, not per policy year.

Why It MattersA Houston household deciding between a 500-dollar and 1,000-dollar collision deductible should evaluate the premium savings against the realistic frequency of out-of-pocket exposure. A 500-dollar deductible difference that saves 200 dollars per year in premium pays for itself in 2.5 years if no claim occurs. TDI consumer materials recommend calibrating the deductible to cash reserves rather than to premium savings alone.
Charles in Plain EnglishThe deductible is your share. The premium reflects it.

SourceTexas Department of Insurance, Auto Coverage Decisions

Direct Repair Program (DRP)

A network arrangement between an auto carrier and specific body shops where the shop agrees to honor pre-negotiated labor rates, parts pricing, and repair procedures in exchange for steered customer volume from the carrier. Texas Insurance Code requires carriers to disclose that DRP shops are not mandatory and that the policyholder has the right to select any qualified Texas body shop.

Why It MattersA Houston household whose carrier steers to a specific DRP shop has the legal right under Texas Insurance Code to use a different shop. DRP shops operate at the carrier's negotiated rates, which can produce shorter cycle time but also pressure on parts decisions (OEM versus aftermarket) and labor hours. TDI consumer materials encourage households to confirm shop choice rights before agreeing to repair authorization.
Charles in Plain EnglishThe carrier picks the rate. The shop picks the bill. You sit between them.

SourceTexas Department of Insurance, Shop Choice Rights

Discount Stack

The combined list of all discounts applied to an auto policy at issue or renewal, including multi-policy, multi-car, loyalty, paperless billing, automatic payment, defensive driver course, good student, low mileage, telematics, advance quote, and homeowner discounts. The discount stack often accounts for 20 to 45 percent of the gross premium before discounts.

Why It MattersHouston households frequently compare carriers on net premium without examining the discount stack underneath. A net premium that depends heavily on a discretionary discount (telematics enrollment, autopay) is more fragile than a net premium built on durable discounts (multi-policy, homeowner). TDI consumer materials recommend households review the discount stack at every renewal to confirm each discount remains earned.
Charles in Plain EnglishDiscounts add up to a number. Read the discounts, not just the number.

Driver Exclusion

A signed endorsement that specifically removes a named individual from all coverage under the auto policy, even when that person is driving an insured vehicle. Driver exclusions are typically used when an individual has a poor driving record, a license suspension, or a claim history that would otherwise make the household uninsurable.

Why It MattersA Houston household that signs a driver exclusion to keep a policy in force must enforce the exclusion. If the excluded driver operates the vehicle and causes an accident, there is no coverage, regardless of permission, regardless of circumstance. TDI consumer materials warn that driver exclusion claims are routinely denied and that the exclusion does not lift even in emergencies.
Charles in Plain EnglishExcluded means excluded. Even once is too many times.

SourceTexas Department of Insurance, Driver Exclusion Rules

E

Endorsement

A document that modifies the standard auto policy by adding, removing, or amending coverage. Common Texas auto endorsements include full glass coverage, rental reimbursement, towing and roadside assistance, named driver exclusion, custom equipment, ride-share, and Mexico coverage. Endorsements typically have their own premium, conditions, and exclusions distinct from the base policy.

Why It MattersA Houston household reviewing the dec page should specifically read the endorsement list, not just the coverage summary. An endorsement removing or restricting coverage is as consequential as one adding it. TDI consumer materials encourage households to obtain the full text of any endorsement before signing. Endorsement language frequently differs from the marketing description.
Charles in Plain EnglishEndorsements add and remove coverage. Read the names. They matter.

SourceTexas Department of Insurance, Auto Endorsements

F

Full Coverage

An informal term commonly used to describe an auto policy that includes liability coverage plus collision and comprehensive coverage on the insured vehicles. Full coverage is not a defined coverage term in the Texas Insurance Code. It is a marketing phrase. What the consumer receives depends on the specific limits, deductibles, and endorsements on the actual policy.

Why It MattersHouston households who buy full coverage frequently discover at claim time that what they bought did not include rental reimbursement, towing, gap coverage, or umbrella protection above the auto limits. TDI consumer materials warn that full coverage is not a regulatory term and recommend households work from the actual coverage list on the dec page rather than the marketing summary.
Charles in Plain EnglishFull coverage is not a contract. It is a marketing word.

SourceTexas Department of Insurance, Understanding Auto Coverage

Full Glass Endorsement

An endorsement that removes the deductible for glass breakage claims (windshield, side windows, rear window, sunroof) and pays the full repair or replacement cost. Without full glass, glass breakage is paid under comprehensive coverage subject to the comprehensive deductible. Full glass is typically a low-premium endorsement (15 to 60 dollars annually) with high claim frequency.

Why It MattersHouston freeway driving, particularly on I-10, US-59, Beltway 8, and the Texas Aggie Expressway, produces high windshield-chip frequency from road debris. TDI consumer materials reference full glass as a high-value endorsement for Houston commuters. State Farm Personal Car Policy Notice 153-7582 details the full glass endorsement provisions used by State Farm in Texas, and similar provisions apply at Allstate and Progressive.
Charles in Plain EnglishWindshields crack on Texas highways. Full glass removes the deductible.

SourceState Farm Personal Car Policy Notice 153-7582

G

Gap Insurance

Coverage that pays the difference between the auto policy's ACV settlement at total loss and the remaining loan or lease balance. Gap insurance is most relevant in the first 24 to 36 months of a vehicle loan, when depreciation typically outpaces principal paydown. Gap is available through the auto carrier, the lender, or as a standalone product.

Why It MattersA Houston household financing a 45,000-dollar vehicle for 72 months and totaling it in year two frequently faces an 8,000 to 12,000-dollar gap between ACV settlement and loan payoff. TDI consumer materials reference gap insurance as essential for households with significant vehicle financing. Gap purchased through the auto carrier is typically lower-cost than gap sold at the dealership.
Charles in Plain EnglishACV pays the carrier value. Gap pays the loan balance.

SourceTexas Department of Insurance, Gap Insurance Guide

H

Hit and Run

An accident where the at-fault driver leaves the scene without providing identification or insurance information. Texas law treats hit-and-run as a criminal offense under the Texas Transportation Code. For insurance purposes, hit-and-run losses are typically paid under the policyholder's Uninsured Motorist coverage, since the at-fault party is effectively uninsured to the victim.

Why It MattersHouston hit-and-run frequency is meaningful, particularly in dense urban traffic and parking-lot environments. Without UM/UIM coverage, a Houston household struck by a hit-and-run driver has no auto-policy recourse for bodily injury or property damage. TDI consumer materials recommend UM/UIM coverage as the primary protection against hit-and-run loss.
Charles in Plain EnglishTexas requires UM to pay. The other driver does not escape the bill.

SourceTexas Department of Insurance, UM/UIM Coverage

I

Insurance Score

A statistical score derived from credit-bureau data and used by auto carriers as one rating factor. Texas law allows the use of insurance scores within specific rules and prohibits sole-reliance on credit data for adverse underwriting actions. TDI regulates how insurance scoring is implemented by Texas-licensed carriers.

Why It MattersA Houston household with a thin credit file, a recent bankruptcy, or a credit-reporting error may receive higher auto rates than driving record alone would justify. Texas allows households to request a reasonable explanation for a higher rate when insurance scoring is involved. The Texas Department of Insurance maintains a complaint process for insurance scoring disputes. Improving credit can produce auto premium reductions over time.
Charles in Plain EnglishCredit affects the auto premium. Texas law allows it within limits.

SourceTexas Department of Insurance, Insurance Scoring Rules

Insurance Verification (TexasSure)

The Texas insurance verification program that requires auto carriers to electronically report active policies to the Texas DMV database, allowing law enforcement and the DMV to confirm coverage in real time. TexasSure replaced the prior paper-card-only system and is the basis for current Texas registration and traffic-stop coverage verification.

Why It MattersA Houston driver renewing vehicle registration must show active coverage through TexasSure. A lapsed policy generates a TexasSure non-confirmation, which can block registration renewal and trigger a traffic-stop citation. TDI consumer materials encourage households to maintain continuous coverage to avoid TexasSure issues. Coverage gaps of even a few days can produce verification problems at the DMV.
Charles in Plain EnglishTexasSure is the database. Texas DMV checks it before you renew the registration.

SourceTexas Department of Insurance, TexasSure Program

L

Lapse

A break in continuous auto coverage. Even a one-day lapse can trigger TexasSure non-confirmation, registration renewal issues, loss of loyalty and continuous-coverage discounts, and higher rates at next placement. Texas carriers report lapses to insurance scoring services, which then affect future rate offers from other carriers.

Why It MattersA Houston household allowing auto coverage to lapse to save one month of premium frequently discovers the lapse cost more than it saved when the next renewal arrives without continuous-coverage discounts. TDI consumer materials warn that lapses produce durable rate consequences. Mortgage and auto escrow arrangements help prevent lapse but can fail during loan transfers or address changes.
Charles in Plain EnglishYou did not lose the discount. The renewal stopped giving it to you.

SourceTexas Department of Insurance, Coverage Lapse Impact

Liability Coverage

The auto coverage that pays for bodily injury and property damage suffered by other people when the policyholder is legally responsible. Liability coverage is required by Texas law on every registered vehicle at the 30/60/25 minimum limit (30,000 bodily injury per person, 60,000 per accident, 25,000 property damage). Higher limits are recommended for households with assets to protect.

Why It MattersTexas minimum liability limits of 30/60/25 are inadequate for most modern accident scenarios. A single luxury-vehicle collision can exhaust the 25,000-dollar property damage limit on the at-fault driver. Multi-injury accidents routinely exceed the 60,000 per-accident bodily injury minimum. TDI consumer materials recommend households with assets carry 100/300/100 or higher, with umbrella coverage above.
Charles in Plain EnglishLiability pays for what you damaged. Not for what you drive.

SourceTexas Department of Insurance, Liability Coverage

Liability-Only

An auto policy that carries only liability coverage (bodily injury and property damage to others) without collision or comprehensive coverage on the insured vehicle. Liability-only is the minimum Texas-legal coverage on a vehicle without a loan. It is appropriate for vehicles with low ACV where the premium for physical damage coverage exceeds the realistic claim recovery.

Why It MattersHouston households frequently apply liability-only thinking to the wrong vehicle (a newer or higher-value vehicle that should carry physical damage coverage) or fail to apply it to the right vehicle (a high-mileage older vehicle that no longer justifies the premium). TDI consumer materials recommend evaluating physical damage coverage based on the vehicle's ACV and the household's cash position.
Charles in Plain EnglishLiability-only is right for the right car. Almost never the right answer for the rest of the garage.

SourceTexas Department of Insurance, Auto Coverage Decisions

M

Material Misrepresentation

An inaccurate or incomplete statement on the auto application that would have affected the carrier's underwriting decision had the truth been known. Material misrepresentation is grounds for policy rescission, claim denial, or cancellation under the Texas Insurance Code. Common areas include undisclosed drivers (see A.D.D.), undisclosed claims history, undisclosed vehicle use (ride-share, business), and undisclosed address.

Why It MattersTexas Insurance Code allows rescission of a policy at any time if material misrepresentation is established, even after a claim has occurred. A Houston household that omits an adult child driver to save premium can face a denied claim and policy rescission. TDI consumer materials warn that material misrepresentation findings produce durable insurability consequences across the Texas market.
Charles in Plain EnglishInaccurate application is one thing. Material misrepresentation is the cancellation.

SourceTexas Department of Insurance, Application Accuracy Requirements

Medical Payments (Med Pay)

An auto coverage that pays for medical expenses incurred by the policyholder and passengers in the insured vehicle, regardless of who was at fault. Med Pay is typically written in limits of 500 to 10,000 dollars per person. Med Pay is distinct from Personal Injury Protection (PIP), which is broader and includes some lost-wages and household-services coverage.

Why It MattersMed Pay provides fast first-dollar coverage for emergency-room and immediate medical costs after a Houston accident, before liability is determined. TDI consumer materials recommend households carry either Med Pay or PIP, and ideally both, particularly in households with children or frequent passengers. Med Pay claim payments do not require fault determination.
Charles in Plain EnglishMed Pay pays regardless of fault. PIP does the same thing differently.

SourceTexas Department of Insurance, Med Pay and PIP

Minimum Limits (Texas 30/60/25)

The minimum auto liability limits required by Texas law on every registered vehicle. 30,000 dollars bodily injury per person, 60,000 dollars bodily injury per accident, 25,000 dollars property damage per accident. The limits are codified in Texas Transportation Code Section 601.072 and have been unchanged since 2011.

Why It MattersTexas minimum limits are among the lowest in the country and are inadequate for almost every modern multi-vehicle or multi-injury accident. A Houston driver who carries only 30/60/25 and causes a serious accident exposes personal assets to the difference between the policy limit and the judgment. TDI consumer materials recommend 100/300/100 or higher with umbrella coverage above for any household with significant assets.
Charles in Plain EnglishState minimums protect the state's mandate. Real limits protect your name.

SourceTexas Transportation Code Section 601.072

MVR (Motor Vehicle Report)

The driving record report issued by the Texas Department of Public Safety or Texas DMV that shows licensed-driver violations, accidents, license suspensions, DUI history, and other driving-record items. MVR data is used by auto carriers as a primary underwriting and rating input. Texas MVRs typically go back three to five years for rating purposes.

Why It MattersA Houston household with one recent moving violation can see auto premiums increase 20 to 40 percent at next renewal because the MVR runs at every renewal cycle for most carriers. TDI consumer materials encourage households to obtain their own MVR before shopping coverage to confirm the record matches what carriers will see. MVR errors do happen and require formal correction through TX DPS.
Charles in Plain EnglishTexas DMV writes the MVR. Carriers read it before they price.

SourceTexas DMV, Motor Vehicle Report Information

Multi-Policy Discount

A premium discount applied when the policyholder carries multiple policies (typically home and auto, sometimes also umbrella, life, or specialty) with the same carrier. Multi-policy discounts typically run 10 to 20 percent on each policy in the bundle. The discount magnitude varies significantly by carrier and policy combination.

Why It MattersMulti-policy discount is one of the most consistent durable discounts available to Houston households, but it should not be the sole driver of carrier selection. A 15 percent multi-policy discount on a non-competitive standalone policy frequently produces a higher net premium than placing each policy separately with the most competitive carrier. TDI consumer materials recommend evaluating each policy on contract and net premium.
Charles in Plain EnglishMulti-policy discount is real. It is not always the largest discount available.

N

Named Driver Policy

An auto policy that covers only specifically named drivers and excludes coverage for anyone else, even with permission to drive the vehicle. Named driver policies are typically offered by non-standard Texas carriers at low premiums. The trade-off is that any driver not named on the policy operates without coverage.

Why It MattersHouston households attracted by named-driver-policy premium savings frequently overlook the practical consequence. A friend, family member, or service-driver operating the vehicle has no liability coverage, no medical payments, and no physical damage coverage. TDI consumer materials warn that named-driver-policy losses are routinely denied for unnamed drivers and that the household remains liable for damages caused.
Charles in Plain EnglishNamed driver covers names listed. Anyone else driving is uninsured.

SourceTexas Department of Insurance, Named Driver Policy Warnings

Non-Owned Auto Coverage

Coverage that applies when the policyholder is driving a vehicle they do not own (rental car, borrowed car from a friend, work vehicle in some circumstances). Non-owned auto coverage extends the policyholder's liability and sometimes physical damage coverage to the non-owned vehicle. Standard Texas auto policies typically include some non-owned coverage automatically.

Why It MattersA Houston household renting a vehicle for a trip frequently does not need the rental counter's collision damage waiver if their auto policy includes non-owned coverage with adequate limits. TDI consumer materials recommend households confirm non-owned coverage scope with the carrier before declining rental-counter coverage. Some non-owned coverage limits apply only to physical damage and not to lost rental income or diminished value.
Charles in Plain EnglishNon-owned auto follows the driver. Not the car.

SourceTexas Department of Insurance, Non-Owned Auto Coverage

Non-Renewal

A carrier decision to not offer continued coverage when the current policy term ends. Non-renewal is distinct from mid-term cancellation. Texas Insurance Code requires advance written notice of non-renewal with specific timeframes (typically 60 days). Non-renewal is most common after multiple claims, after a driver-record event, or after underwriting changes affecting the household profile.

Why It MattersA Houston household receiving a non-renewal notice has time to place replacement coverage before the current policy expires, but should treat the notice as urgent. Non-renewal history affects future placement and can result in higher non-standard market rates. TDI consumer materials recommend households contact a Texas-licensed broker immediately upon receipt of a non-renewal notice.
Charles in Plain EnglishCancellation ends the term mid-policy. Non-renewal lets it expire.

SourceTexas Department of Insurance, Cancellation and Non-Renewal

O

OEM Parts

Original Equipment Manufacturer parts. Replacement parts produced by the same manufacturer that supplied the vehicle's original parts, typically with manufacturer warranty and exact-fit specifications. OEM parts are higher cost than aftermarket alternatives but ensure factory-grade structural integrity, paint match, and fit.

Why It MattersHouston body-shop disputes frequently center on OEM-versus-aftermarket parts decisions. The John Eagle Collision Center case in Texas demonstrated that structural-repair quality on collision-critical parts has lasting safety implications. The Texas Department of Insurance specifies that policyholders have the right to insist on OEM parts under many circumstances, particularly when aftermarket alternatives are not certified to OEM-equivalent specifications.
Charles in Plain EnglishOEM is the original manufacturer. Aftermarket is everything else.

P

Permissive Use

Coverage that extends to a driver who is operating the insured vehicle with the named insured's permission, even if the driver is not listed on the policy. Permissive use is a default provision in most Texas auto policies, subject to specific exclusions (named driver exclusions, household members specifically excluded, vehicles used for business).

Why It MattersA Houston household lending a vehicle to a neighbor for a quick errand typically has coverage in place under permissive use, but the coverage extension is not unlimited. Some carriers reduce permissive-use coverage to state minimums when the driver is not a named insured. TDI consumer materials encourage households to confirm permissive-use scope at policy issue.
Charles in Plain EnglishThe keys in the bowl are insured. Texas calls it permissive use.

SourceTexas Department of Insurance, Permissive Use Coverage

Personal Injury Protection (PIP)

A Texas auto coverage that pays medical expenses, lost wages, and household services costs for the policyholder and passengers, regardless of who was at fault. Texas PIP minimum is 2,500 dollars per person. Texas law requires carriers to offer PIP on every auto policy, and the policyholder must reject PIP coverage in writing to decline it.

Why It MattersPIP pays first dollar after a Houston accident, without waiting for fault determination or liability negotiation. TDI consumer materials recommend PIP coverage of 5,000 to 10,000 dollars per person for most Houston households. Households with high-deductible health insurance benefit particularly from PIP because it covers medical costs without the health-plan deductible application.
Charles in Plain EnglishPIP pays first. Med Pay pays alongside. UM/UIM pays after.

Premium

The amount paid to the auto carrier for coverage during the policy term. Auto premium is calculated from rating factors including driver record, vehicle, coverage limits, deductibles, location, credit-based insurance score, and discount stack. Premium is typically billed annually, semi-annually, quarterly, or monthly with corresponding finance charges on installment plans.

Why It MattersA Houston household comparing carriers should compare net premium, the contract details, the discount stack, and the historical rate-change behavior of each carrier. TDI consumer materials warn that lowest-premium quotes frequently reflect thinner contracts or temporary new-customer discounts that revert at renewal. Premium stability matters as much as initial premium.
Charles in Plain EnglishPremium is what you pay. Limits are what you own.

Property Damage Liability

The auto liability coverage that pays for damage to the property of others (their vehicle, mailbox, fence, building, structures) when the policyholder is legally responsible. Texas minimum property damage liability is 25,000 dollars per accident (the 25 in 30/60/25). Higher limits are typically 50, 100, or 250 thousand dollars.

Why It MattersA single luxury-vehicle collision can exhaust the 25,000-dollar Texas minimum on the at-fault driver. A Houston driver who causes substantial property damage with only state minimum coverage is personally liable for the difference between policy limit and actual damage. TDI consumer materials recommend households evaluate property damage limits against the realistic value of vehicles encountered on Houston roads.
Charles in Plain EnglishPD pays for the bumper. BI pays for the bone.

R

Rental Reimbursement

An endorsement that pays for a rental vehicle while the insured vehicle is being repaired after a covered loss. Rental reimbursement is typically written as a daily limit (commonly 30 to 75 dollars per day) and a maximum total benefit (commonly 900 to 1,500 dollars per loss). The endorsement is inexpensive (20 to 60 dollars annually) and high-value at claim time.

Why It MattersA Houston household whose vehicle is in the shop for two weeks after a hail or collision claim faces 400 to 1,200 dollars in rental costs depending on vehicle class. A 30-dollar-per-day rental limit no longer covers an SUV or pickup in 2026. TDI consumer materials encourage households to review the daily limit at renewal because rental costs have risen significantly. Many major carriers offer Texas rental reimbursement with different daily-limit options.
Charles in Plain English30 dollars a day was a fair number in 2010. In 2026 it does not even cover an SUV.

SourceAllstate, Rental Reimbursement Coverage

Renewal

The continuation of an auto policy for another term, typically 6 or 12 months. The carrier issues a renewal notice with the new premium, any rate changes, any coverage changes, and the renewal effective date. Renewal is the only structured moment in the policy lifecycle when both the carrier and the policyholder formally re-engage with the contract.

Why It MattersMost Houston households renew on autopay without reading the renewal notice. TDI consumer materials recommend households perform a contract-to-contract renewal review at every renewal cycle. Renewal-time rate changes, coverage changes, deductible changes, and endorsement changes typically appear on the renewal declarations page but are easy to miss without an active review.
Charles in Plain EnglishThe renewal is the only conversation the carrier offers. Have it before you sign.

S

SR-22

A Texas DPS-required certificate of financial responsibility filed by the auto carrier confirming the policyholder carries at least state minimum liability coverage. SR-22 filings are typically required after specific events including DUI conviction, driving without insurance, license suspension reinstatement, and certain repeat-offender circumstances. The SR-22 itself is not coverage. It is documentation of coverage.

Why It MattersA Houston driver required to file SR-22 typically faces higher premiums during the SR-22 period (commonly two to three years). The carrier filing the SR-22 must report any lapse in coverage to Texas DPS, which can trigger license action. TDI consumer materials encourage SR-22 households to maintain continuous coverage through carriers that specifically offer SR-22 filing.
Charles in Plain EnglishSR-22 is not coverage. It is the carrier telling Texas you carry coverage.

SourceTexas Department of Public Safety, SR-22 Requirements

Stated Value

A coverage basis where the policyholder declares a vehicle value at policy issue, and the carrier rates the policy on that declared amount, but the carrier reserves the right to pay the lesser of the stated value or ACV at total loss. Stated Value differs from Agreed Value, where the stated amount is contractually paid regardless of ACV.

Why It MattersA Houston classic-car owner buying Stated Value coverage and assuming the stated amount will be paid at total loss can be surprised by a settlement based on ACV instead. TDI consumer materials warn that Stated Value is not Agreed Value. Specialty carriers Hagerty, Grundy, and American Modern offer true Agreed Value policies for classic, antique, and collector vehicles in Texas.
Charles in Plain EnglishStated Value is what you said. Agreed Value is what the carrier signed.

Subrogation

The auto carrier's right to pursue recovery from the at-fault third party after paying the policyholder's claim. If the policyholder's collision coverage paid a 12,000-dollar repair caused by an at-fault driver with low liability limits, the carrier can sue the at-fault driver to recover the 12,000 dollars. Successful subrogation can return the policyholder's deductible.

Why It MattersSubrogation operates in the background of most auto claims and typically does not require policyholder action beyond cooperation. TDI regulates carrier subrogation practices to protect policyholders. Some subrogation recoveries return the deductible. Most do not directly benefit the policyholder but are essential to carrier economics and to maintaining premium discipline.
Charles in Plain EnglishSubrogation is the carrier's right. Sometimes your deductible comes back with it.

T

Texas Department of Insurance (TDI)

The Texas state agency that regulates insurance carriers, licenses agents and brokers, enforces the Texas Insurance Code, investigates consumer complaints, publishes consumer guides, and approves policy forms for use in Texas. TDI is the primary state-level authority for all Texas auto insurance matters.

Why It MattersHouston households with carrier disputes, coverage interpretation questions, or complaint resolution needs can file directly with TDI without going through the carrier first. The Texas Department of Insurance maintains a complaint database, a market-conduct examination program, and a consumer assistance team. TDI does not write policies. TDI regulates the entities that do.
Charles in Plain EnglishTDI regulates Texas insurance. TDI does not write your policy.

Texas Insurance Code Section 1952.301

The Texas statute governing auto insurance labor rate reimbursement on collision repair. Section 1952.301 requires carriers to pay reasonable and necessary repair costs based on prevailing labor rates in the geographic area, not on carrier-preferred rates. The statute is the legal foundation for Texas body-shop labor rate disputes.

Why It MattersHouston body shops regularly cite Section 1952.301 when negotiating labor rates with carriers that attempt to enforce below-prevailing-rate reimbursement. TDI consumer materials point body shops and policyholders to the statute when labor-rate disputes arise. The policyholder has the right to insist that the carrier pay the prevailing rate at a qualified Texas body shop, even when the shop is outside the carrier's Direct Repair Program network.
Charles in Plain EnglishSection 1952.301 is the labor rate statute. The shop has the right. The carrier has the obligation.

SourceTexas Insurance Code Section 1952.301

Total Loss

The determination that the cost of repairing a damaged vehicle exceeds a defined percentage of its pre-loss ACV, typically 70 to 80 percent depending on carrier policy. Total loss triggers an ACV settlement (or Agreed Value if applicable) rather than continued repair authorization. Texas DMV salvage and title rules apply to total-loss vehicles.

Why It MattersA Houston total-loss settlement can produce surprise outcomes when ACV falls below loan balance (gap exposure), when ACV does not reflect the vehicle's actual market position (recent appreciation, low-mileage premium), or when the policyholder wishes to retain the salvage. TDI consumer materials encourage households to negotiate ACV with documentation of comparable Houston-area sales rather than accepting the carrier's first valuation.
Charles in Plain EnglishRepair costs cross the threshold. Texas calls it a total loss.

SourceTexas Department of Insurance, Total Loss Settlement

Towing & Roadside Assistance

An endorsement that pays for towing, jump-starts, flat-tire change, lockout service, fuel delivery, and basic mechanical assistance when the insured vehicle becomes disabled. Towing and roadside is typically a low-cost endorsement (15 to 50 dollars annually) with high practical utility, particularly for Houston commuters facing heavy I-10, US-59, or Beltway 8 traffic.

Why It MattersA Houston household with a flat tire on 290 at 6 PM during rush hour values roadside assistance significantly. TDI consumer materials recommend roadside coverage particularly for households with newer vehicles where dealership service requirements may complicate independent service-call options. Many major carriers offer Texas roadside endorsements, but availability and terms depend on the policy form and current carrier appetite.
Charles in Plain EnglishTowing is the small-dollar coverage. Until you need it at 2 AM in the rain.

SourceTexas Department of Insurance, Auto Endorsements

U

Underinsured Motorist (UIM)

An auto coverage that pays for bodily injury or property damage when the at-fault driver carries liability coverage, but at limits insufficient to cover the loss. UIM bridges the gap between the at-fault driver's actual liability limits and the policyholder's full damages, up to the UIM limit. Texas allows UIM at the same limits as the insured's underlying liability.

Why It MattersA Houston driver injured by a Texas-minimum-limits (30/60/25) at-fault driver in a serious accident can face medical bills well above the at-fault driver's coverage. Without UIM, the policyholder is left to collect from a likely-judgment-proof at-fault party. TDI consumer materials recommend UIM at limits matching or exceeding underlying liability. Approximately 20 percent of Texas drivers carry no coverage at all, and many more carry only state minimums.
Charles in Plain EnglishUM is for the driver with no insurance. UIM is for the one with too little.

SourceTexas Department of Insurance, UM/UIM Coverage

Uninsured Motorist (UM)

An auto coverage that pays for bodily injury or property damage when the at-fault driver carries no auto insurance at all, including hit-and-run scenarios where the at-fault driver is unidentifiable. Texas law requires carriers to offer UM coverage. The policyholder must reject UM in writing to decline it.

Why It MattersTexas DMV data indicates approximately 20 percent of Texas drivers carry no auto insurance. A Houston driver involved in an accident with an uninsured at-fault driver has no recourse against that driver in most cases. TDI consumer materials recommend UM coverage at limits matching underlying liability. UM is among the most valuable Texas auto coverages relative to its premium cost.
Charles in Plain EnglishTexas allows you to reject UM in writing. Almost nobody should.

SourceTexas Department of Insurance, UM/UIM Coverage

Underwriting

The carrier process of evaluating risk, accepting or declining the application, and pricing the policy based on rating factors including driver record, vehicle, location, credit-based insurance score, coverage selections, and prior claims. Underwriting decisions can change at renewal as carrier appetite shifts or as the policyholder's profile changes.

Why It MattersA Houston household offered favorable underwriting at policy issue may face changes at renewal if Texas market conditions shift, if the carrier reduces appetite for the household's vehicle class or zip code, or if the household's driving record changes. TDI consumer materials encourage households to confirm underwriting decisions at every renewal and to shop coverage if the carrier's appetite materially shifts.
Charles in Plain EnglishUnderwriting decides whether you buy. And what you pay if they say yes.

V

Vehicle Identification Number (VIN)

The unique 17-character identifier assigned to every motor vehicle by the manufacturer, used to identify the specific vehicle on every auto policy document, registration, title, and claim file. The VIN encodes the manufacturer, model year, plant, vehicle attributes, and serial sequence. Texas DMV requires VIN verification for registration and title transactions.

Why It MattersEvery coverage decision on a Houston auto policy ties back to the specific VIN. A policy issued on the wrong VIN, an obscured or transcribed VIN error, or a VIN-vehicle mismatch can produce claim denials. TDI consumer materials encourage households to verify VIN accuracy on every renewal dec page. VIN errors are surprisingly common during vehicle additions, replacements, and dealer-arranged coverage placements.
Charles in Plain EnglishThe VIN is the car's fingerprint. Every term on the policy points to it.

The McDade Standard

Contract to contracts.

"Texas auto is the most-touched insurance contract most households own. Two or three drivers. Multiple vehicles. Renewal every six months on autopay. Most people never read the dec page. Texas minimum limits of 30/60/25 are inadequate for almost every modern accident. UM/UIM is the most valuable Texas coverage relative to premium. About 40 percent of the time we tell clients to keep the auto they have. The other 60 percent is where we find a structural issue (underinsured liability, missing UM/UIM, wrong A.D.D. disclosure, ACV gap on a financed vehicle) that would have cost them the savings the carrier promised."

Frequently Asked Questions

The questions worth asking before the next renewal.

What is auto insurance terminology and why does it matter for Houston households?

Texas auto insurance is a contract built from defined terms that decide what gets paid, when, and how much. Minimum limits of 30/60/25 are the legal floor under Texas Transportation Code Section 601.072, but they are inadequate for most modern accident scenarios. UM/UIM coverage protects against the approximately 20 percent of Texas drivers who carry no insurance and the many more who carry only minimum limits. Section 1952.301 of the Texas Insurance Code governs labor rate reimbursement when your vehicle is in the body shop. Most Texas households sign their auto policy without understanding the language inside it. The McDade Auto Insurance Glossary defines 55 Texas auto terms in plain English so you can read your declarations page line by line.

What are Texas minimum liability limits and are they enough?

Texas minimum liability limits are 30/60/25. That is 30,000 dollars bodily injury per person, 60,000 dollars bodily injury per accident, 25,000 dollars property damage per accident. The limits are codified in Texas Transportation Code Section 601.072 and have been unchanged since 2011. They are inadequate for most modern accident scenarios. A single luxury-vehicle collision can exhaust the 25,000 dollar property damage limit. A multi-injury accident routinely exceeds the 60,000 dollar per-accident bodily injury minimum. TDI consumer materials recommend households with assets carry 100/300/100 or higher, with umbrella coverage above. Real limits protect your name. State minimums only protect the state's mandate.

What is Additional Driver Discovery (A.D.D.) and how does it affect my Houston policy?

Additional Driver Discovery is a carrier underwriting practice. The carrier discovers undisclosed drivers in your household through public records, social media, license-plate scanning, and credit-bureau cohabitation data, then adds those drivers to your policy and bills retroactively or at renewal. Progressive and several other Texas-active carriers run A.D.D. on a regular basis. Houston households frequently exclude an adult child, a roommate, or a domestic partner from the application to keep premium low. A.D.D. discovers the omission, often months later. The Texas Department of Insurance has issued consumer alerts about A.D.D. practice and recommends disclosing every regular driver at policy issue to avoid mid-term repricing or material misrepresentation findings.

What is the difference between Agreed Value and Stated Value on a Texas auto policy?

Stated Value is what you said. Agreed Value is what the carrier signed. With Stated Value, you declare a vehicle value at policy issue and the carrier rates the policy on that declared amount, but the carrier reserves the right to pay the lesser of stated value or ACV at total loss. With Agreed Value, the stated amount is contractually paid regardless of ACV. Houston classic-car owners assuming Stated Value protects them at total loss can be surprised by an ACV-based settlement instead. Specialty carriers Hagerty, Grundy, and American Modern offer true Agreed Value policies for classic, antique, and collector vehicles in Texas. TDI consumer materials recommend specialty placement for any vehicle meeting collector criteria.

How does Texas comparative fault affect my auto claim?

Texas operates under modified comparative fault with a 51 percent bar, codified in Texas Civil Practice and Remedies Code Chapter 33. A plaintiff who is 50 percent or less at fault recovers damages, reduced by their percentage of fault. A plaintiff who is 51 percent or more at fault recovers nothing. A driver 30 percent at fault who would otherwise recover 100,000 dollars instead recovers 70,000 dollars. A driver 51 percent at fault recovers zero. Houston multi-vehicle accidents frequently produce comparative-fault assignments that change settlement amounts dramatically. TDI consumer materials encourage households disputing fault percentages to consult with a Texas personal-injury attorney before accepting any settlement offer.

What is Texas Insurance Code Section 1952.301?

Section 1952.301 is the Texas statute governing auto insurance labor rate reimbursement on collision repair. It requires carriers to pay reasonable and necessary repair costs based on prevailing labor rates in the geographic area, not on carrier-preferred rates. Houston body shops regularly cite Section 1952.301 when negotiating labor rates with carriers that attempt to enforce below-prevailing-rate reimbursement. The policyholder has the right to insist that the carrier pay the prevailing rate at a qualified Texas body shop, even when the shop is outside the carrier's Direct Repair Program network. TDI consumer materials point body shops and policyholders to the statute when labor-rate disputes arise.

Do I need UM/UIM coverage if I have good liability limits?

Yes. UM and UIM coverage protect you against the at-fault driver, not against your own conduct. Texas DMV data indicates approximately 20 percent of Texas drivers carry no auto insurance at all. Many more carry only the 30/60/25 minimum. A Houston driver injured by an uninsured or underinsured at-fault driver in a serious accident has no recourse against that driver beyond UM and UIM coverage on their own policy. TDI consumer materials recommend UM and UIM at limits matching or exceeding underlying liability. UM and UIM are among the most valuable Texas auto coverages relative to premium cost. Texas allows rejection of UM in writing. Almost nobody should reject it.

What is the difference between OEM parts and aftermarket parts in a Texas auto claim?

OEM parts are Original Equipment Manufacturer parts produced by the same manufacturer that supplied the vehicle's original parts, with manufacturer warranty and exact-fit specifications. Aftermarket parts are produced by other companies, typically at lower cost. Texas Insurance Code requires carriers to disclose the use of aftermarket parts on the repair estimate and to certify like-kind-and-quality equivalence. Houston body-shop disputes frequently center on OEM-versus-aftermarket decisions. The John Eagle Collision Center case in Texas demonstrated that structural-repair quality on collision-critical parts has lasting safety implications. The Texas Department of Insurance specifies that policyholders have the right to insist on OEM parts under many circumstances, particularly when aftermarket alternatives are not certified to OEM-equivalent specifications.

What is Personal Injury Protection (PIP) and should I keep it?

PIP is a Texas auto coverage that pays medical expenses, lost wages, and household services costs for the policyholder and passengers, regardless of who was at fault. Texas PIP minimum is 2,500 dollars per person. Texas law requires carriers to offer PIP on every auto policy, and the policyholder must reject PIP coverage in writing to decline it. PIP pays first dollar after a Houston accident, without waiting for fault determination or liability negotiation. TDI consumer materials recommend PIP coverage of 5,000 to 10,000 dollars per person for most Houston households. Households with high-deductible health insurance benefit particularly from PIP because it covers medical costs without health-plan deductible application.

Why use the McDade Auto Insurance Glossary instead of a generic auto glossary?

Generic auto glossaries define terms in general. The McDade Auto Insurance Glossary defines them for Houston households with the specific context of the Texas Insurance Code, Texas Department of Insurance state rules, Texas DMV requirements, Texas court precedent on comparative fault and material misrepresentation, and the policy form differences we see across the Texas auto market. Every definition includes why the term matters at claim time, what to look for on your declarations page, and a citation to the regulatory or carrier source where applicable. The goal is not to teach insurance vocabulary. The goal is to help you read your contract honestly before signing for another year.
