Car Insurance Terms Explained: Glossary of Pricing Words

A

Actual cash value: What your car was worth just before the loss: roughly what it would cost to buy one of the same make, model, age, mileage and condition. It is what collision and comprehensive pay on a total loss, minus your deductible.
Adverse action notice: A notice the Fair Credit Reporting Act requires when information in a consumer report, such as a credit report, leads an insurer to charge you more or refuse coverage. It names the bureau that supplied the report and tells you how to get a free copy and dispute errors. More: Credit-based insurance scores
Assigned risk plan: A state program for drivers the regular market turns down, so they can still buy the coverage the law requires. Applications usually go through a licensed agent, prices are higher and coverage options are narrower. Texas's plan is the Texas Automobile Insurance Plan Association. More: Assigned-risk plans
At-fault accident: A crash in which you are found mainly responsible. It usually adds a surcharge at renewal for a set number of years; how fault is decided and how long it counts depend on the insurer and the state. More: Driving record
Average expenditure: The NAIC's measure of what an insured car costs on average in a state: total premiums divided by the number of insured car-years. It mixes liability-only cars with fully covered ones, so it runs below the combined premium. The U.S. figure for 2023 was $1,282. More: Texas

B

Binder: Temporary written proof of coverage that an insurer or agent issues before the policy itself is ready, for example so you can drive a newly bought car off the lot.
Broker: A licensed intermediary who, in many states, legally represents the buyer rather than an insurer. Licensing titles differ by state, and many states call agents and brokers alike insurance producers.

C

Cancellation: Ending a policy before its term is over. You can cancel at any time; an insurer's right to cancel mid-term is limited by state law, usually to reasons such as nonpayment, fraud or a suspended license, and it must give written notice first. More: Switching insurers without a gap
Captive agent: An agent who sells the policies of one insurance company or group. A captive agent can compare that company's options but not other insurers' prices. More: Comparing quotes line by line
CLUE report: Your record in the Comprehensive Loss Underwriting Exchange, a claims database run by LexisNexis Risk Solutions that insurers check when they quote. Under the Fair Credit Reporting Act you can get a free copy every 12 months and dispute errors. Verisk's A-PLUS is a similar database. More: Claims history
Collision coverage: Pays to repair or replace your car after it hits another vehicle or an object, or rolls over, whoever was at fault, minus your deductible. State law doesn't require it, but a lender or leasing company usually does. The U.S. average collision premium was $464 in 2023 (NAIC). More: Raising your deductible
Combined premium: The NAIC's average for a car that carries liability, collision and comprehensive together, which is close to what people call full coverage. The U.S. figure for 2023 was $1,438. More: Texas
Combined single limit: A liability limit written as one amount, such as $300,000, that covers injuries and property damage from one crash together instead of splitting them into three separate limits. More: Coverage limits and deductibles
Comprehensive coverage: Pays for damage to your car from causes other than a collision, such as theft, fire, hail, flooding, vandalism or hitting an animal, minus your deductible. The U.S. average comprehensive premium was $238 in 2023 (NAIC). More: Raising your deductible
Continuous coverage: An insurance history with no gaps. Insurers often price a driver with continuous coverage lower than one with a recent lapse, and some reward years spent with the same company. More: Insurance lapse
Credit-based insurance score: A score built from your credit report to predict how likely you are to file a claim, not whether you will repay a loan. Most states allow it in car insurance pricing; California, Hawaii and Massachusetts don't allow credit in auto pricing, and Michigan bars credit scores from auto rates. More: Credit-based insurance scores

D

Declarations page: The summary page of your policy: the people insured, listed drivers and cars, the policy period, each coverage with its limit or deductible, discounts and the premium. It is the starting point for comparing quotes. More: Reading your declarations page
Deductible: The part of a collision or comprehensive claim you pay before the insurer pays the rest. A higher deductible lowers the premium, which pays off only if you can cover the deductible from savings. More: Raising your deductible

E

Effective date: The date, and often the exact time, coverage begins. When you switch insurers, start the new policy on or before the day the old one ends. More: Switching insurers without a gap
Endorsement: A written change or addition to the standard policy, such as rental reimbursement or coverage for custom equipment. Endorsements are listed on the declarations page and usually add to the premium. More: Reading your declarations page

F

File and use: A system of rate regulation in which an insurer files its rates with the state and may start using them without advance approval, sometimes after a waiting period; the regulator can still reject them later. Under use and file, the insurer files within a set time after it starts using the rates. More: Complaining about a rate increase
FR-44: A certificate like the SR-22, used in Florida and Virginia mainly after alcohol-related driving convictions, that proves you carry liability limits higher than the state minimum. More: Assigned-risk plans
Full coverage: An informal name, not a policy type, for liability plus collision and comprehensive. It doesn't mean every loss is paid: limits, deductibles and exclusions still apply. More: Coverage limits and deductibles

G

Gap insurance: Pays the difference between your car's actual cash value and what you still owe on the loan or lease if the car is totaled or stolen. It matters most early in a loan with a small down payment. More: Trimming optional coverages
Garaging address: Where your car is usually kept overnight. Insurers price the policy on it, and giving a wrong address to get a lower price can lead to a denied claim or a cancelled policy. More: Location and ZIP code

I

Independent agent: An agent who can quote and sell policies from several insurers, so one conversation can return more than one price. More: Comparing quotes line by line
Installment fee: A charge added to each payment when you pay the premium in installments instead of all at once. Some insurers lower it for automatic payments from a bank account. More: Paying in full vs. monthly
Insurance department: The state agency that licenses insurers and agents, reviews rates and policy forms, and takes consumer complaints. The name varies by state, for example the Texas Department of Insurance or the Florida Office of Insurance Regulation. More: Complaining about a rate increase

L

Lapse: A period when a car or driver has no insurance, for example after a missed payment or a switch that started a day late. Insurers usually charge more after a lapse, and driving uninsured can bring state penalties. More: Insurance lapse
Liability coverage: Pays for injuries (bodily injury liability) and damage (property damage liability) you cause to other people in a crash, up to your limits, and for your legal defense if you are sued. It is the coverage state laws require, in some form, in nearly every state. More: Coverage limits and deductibles
Liability limits (25/50/25): The most your liability coverage pays, written in thousands of dollars: 25/50/25 means $25,000 for one person's injuries, $50,000 for all injuries in one crash and $25,000 for property damage. Texas, for example, requires at least 30/60/25. More: Coverage limits and deductibles
Lienholder: The lender or leasing company with a financial interest in your car. It is listed on the policy so it is paid on a total loss, usually requires collision and comprehensive, and must be told when you change insurers. More: Switching insurers without a gap
Low-mileage discount: A lower price for driving fewer miles a year than the insurer's threshold. Insurers may verify mileage with odometer readings or photos, or with a telematics app or device. More: Annual mileage

M

Medical payments coverage (MedPay): Pays medical bills for you and your passengers after a crash, whoever was at fault, up to a usually modest limit. Unlike PIP it doesn't pay lost wages, and it can overlap with health insurance. More: Trimming optional coverages
Motor vehicle insurance price index: The Bureau of Labor Statistics' measure of car insurance prices within the Consumer Price Index. It was 5.0% lower in September 2026 than a year earlier, after a 2.8% rise in the 12 months to December 2025. More: Why your premium went up
Multi-policy discount: A discount for buying more than one policy, such as auto and home or renters insurance, from the same insurer. It is also called a bundling discount. More: Bundling home and auto

N

No-fault insurance: A system in which your own personal injury protection pays your medical bills and lost wages after a crash, whoever caused it, and your right to sue the other driver for injuries is limited unless they pass a threshold set by state law. A few states let drivers choose between no-fault and the traditional tort system.
Non-owner policy: Liability insurance for someone who drives but doesn't own a car, often used to keep coverage continuous or to meet an SR-22 requirement. It doesn't pay for damage to the car you are driving. More: Insurance lapse
Nonrenewal: An insurer's decision not to offer a new term when your policy ends. Most states require written notice in advance, and some limit the reasons an insurer may use; that notice period is your time to shop. More: When to shop for car insurance

P

Paid-in-full discount: A discount some insurers give when you pay the whole term up front. Giving it up is part of what a monthly plan really costs. More: Paying in full vs. monthly
Pay-per-mile insurance: A policy priced as a monthly base charge plus a rate for each mile driven, measured by an app or a device in the car. It tends to suit drivers who don't drive much. More: Pay-per-mile insurance
Personal injury protection (PIP): Pays medical bills, and depending on the state lost wages and other costs, for you and your passengers after a crash, whoever caused it. No-fault states require it; some other states include it unless you reject it in writing, as Texas does.
Premium: The price of your policy for its term, usually six or twelve months, after every rating factor, discount and surcharge has been applied. More: Why your premium went up
Prior approval: A system of rate regulation in which the state insurance department must approve a rate before an insurer can use it. California's Proposition 103 requires prior approval of car insurance rates. More: Complaining about a rate increase
Pro rata refund: A refund of unused premium in exact proportion to the time left on the policy. If you paid $600 for six months and cancel after three, a pro rata refund is $300. More: Switching insurers without a gap
Property damage liability: The part of liability coverage that pays for damage you cause to other people's property, mostly their cars. Florida requires it, along with PIP, even though it doesn't require bodily injury liability for most drivers.

Q

Quote: An insurer's estimate of the premium for the drivers, cars and coverage you describe. It can change once the insurer checks your driving record, claims history and, where allowed, credit. More: Comparing quotes line by line

R

Rate filing: The package an insurer submits to a state regulator to set or change its rates: the rates themselves, the rating rules and the data behind them. Many states let the public read filings online. More: Complaining about a rate increase
Rating factor: Any fact an insurer uses to price a policy, such as your driving record, claims history, age, ZIP code, car, mileage and chosen coverage, and your credit-based insurance score where state law allows it. Each insurer weighs them according to the rating plan it files with the state. More: Driving record
Renewal: The start of a new policy term with the same insurer, at a price the insurer may change. The renewal notice is a natural moment to compare quotes. More: When to shop for car insurance
Rental reimbursement: An add-on that pays a daily amount, up to a cap, for a rental car while yours is repaired after a covered claim. More: Trimming optional coverages
Residual market: The ways states make coverage available to drivers the voluntary market won't insure: assigned risk plans, joint underwriting associations, reinsurance facilities and state funds such as the Maryland Automobile Insurance Fund. More: Assigned-risk plans

S

SERFF: The System for Electronic Rates & Forms Filing, run by the NAIC, which insurers use to send rate and policy-form filings to states. Many states offer public SERFF Filing Access sites where you can read an insurer's filings. More: Complaining about a rate increase
Short-rate cancellation: A refund method that keeps a cancellation charge, so you get back less than the pro rata amount. Whether an insurer may use it depends on the policy and state rules, so ask before you cancel. More: Switching insurers without a gap
SR-22: A certificate your insurer files with the state to prove you carry the required liability insurance, usually demanded after a DUI, driving uninsured, serious violations or a license suspension. It isn't a type of insurance, but the record behind it raises the premium, and the insurer must tell the state if the policy ends. More: Assigned-risk plans
Stacking: Adding together the uninsured or underinsured motorist limits of several cars on one policy, or of several policies, so one claim can draw on a higher total. States differ on whether stacking is allowed or can be waived, and stacked coverage costs more. More: Comparing quotes line by line
State minimum coverage: The least insurance state law lets you drive with. Several minimums rose recently, such as North Carolina's to 50/100/50 in July 2025 and Hawaii's to 40/80/20 in January 2026. A minimum policy costs less but can leave you paying for a serious crash yourself. More: Coverage limits and deductibles
Surcharge: An extra charge added to the premium for an at-fault accident or a traffic conviction, usually for a fixed number of years. In North Carolina, convictions on or after July 1, 2025 that carry four or more insurance points are surcharged for five years instead of three. More: Driving record

T

Telematics: Collecting driving data such as mileage, speed, hard braking, time of day and phone use through an app or a device in the car, so an insurer can price the policy on how you drive. More: Telematics and usage-based insurance
Territory rating: Pricing by where the car is kept. Insurers group ZIP codes or areas into rating territories with different base rates, which is why moving across town can change your premium. More: Location and ZIP code
Tort system: The fault-based system most states use: the driver who causes a crash, through their liability insurance, pays for other people's injuries and damage, and injured people can sue for their losses.
Total loss: A car the insurer decides isn't worth repairing, typically because the repair bill would approach or exceed its value or a threshold set by state law. Collision or comprehensive then pays the actual cash value minus your deductible.

U

Underinsured motorist coverage (UIM): Pays the rest of your injury costs when the at-fault driver's liability limits are too low to cover them. North Carolina has included it in every new and renewed policy since July 1, 2025.
Uninsured motorist coverage (UM): Pays for your injuries, and in some states damage to your car, when a driver with no insurance causes the crash; many policies also apply it to hit-and-run drivers. The Insurance Research Council estimated that 15.4% of U.S. drivers were uninsured in 2023.
Usage-based insurance: A policy priced partly on telematics data about how, how much or when you drive. Some programs give a discount for enrolling; whether the price can also go up depends on the insurer and the state. More: Telematics and usage-based insurance
