Educational Note: This page provides general educational information only. Your policy documents and insurer determine how your coverage actually works.
This Insurance Glossary is a helpful starting point, not personal insurance advice.
A–C Auto Insurance Terms
Actual Cash Value
Actual cash value is a vehicle’s estimated value before a covered loss. It usually considers age, condition, mileage, market value, and depreciation.
Adjuster
An adjuster reviews a claim for an insurance company. The adjuster may inspect damage, collect facts, and estimate covered costs.
Agent
An insurance agent helps customers understand and purchase insurance policies. Some agents represent one insurer, while others offer several companies.
At-Fault Accident
An at-fault accident is one where a driver caused the crash. Fault rules and financial responsibility can differ between states.
Bodily Injury Liability
Bodily injury liability may pay for injuries you cause to others. It can also help with related legal defense costs.
Claim
A claim is a request for payment under an insurance policy. The insurer reviews the event before approving or denying payment.
Collision Coverage
Collision coverage may pay for damage to your vehicle after a crash. It usually applies after you pay the selected deductible.
Comprehensive Coverage
Comprehensive coverage may pay for damage not caused by a collision. Examples can include theft, hail, fire, vandalism, or falling objects.
Coverage Limit
A coverage limit is the most an insurer may pay. Different parts of one policy can have separate limits.
D–F Auto Insurance Terms
Declarations Page
The declarations page summarizes important details about your policy. It often lists drivers, vehicles, coverages, limits, deductibles, and policy dates.
Deductible
A deductible is the amount you pay toward a covered claim. A higher deductible may reduce premiums but increases your personal cost.
Depreciation
Depreciation is the reduction in a vehicle’s value over time. Age, mileage, wear, condition, and market demand can affect depreciation.
Endorsement
An endorsement changes, adds, or removes terms in an insurance policy. It may also be called a policy amendment or rider.
Exclusion
An exclusion describes something the policy does not cover. Read exclusions carefully because they can limit claim payments.
Financial Responsibility Law
Financial responsibility laws require drivers to cover certain accident-related losses. Most drivers meet this requirement through auto liability insurance.
Use this Insurance Glossary when reviewing unfamiliar wording in a quote. Always compare each definition with the actual policy documents.
G–L Auto Insurance Terms
Gap Coverage
Gap coverage may help when a financed vehicle becomes a total loss. It can cover part of the difference between value and loan balance.
Grace Period
A grace period is extra time allowed for certain payments. Not every insurer or payment situation includes a grace period.
Insured
The insured is the person or organization protected by the policy. A policy may include named insureds and other covered drivers.
Insurer
The insurer is the company that issues the insurance policy. It collects premiums and handles claims under the policy terms.
Lapse
A lapse occurs when coverage ends because the policy was not maintained. Driving during a lapse can create financial and legal risks.
Liability Coverage
Liability coverage may pay for injuries or property damage you cause. Required limits and available options vary by state.
Loss
A loss is an event that may lead to an insurance claim. Examples include crashes, theft, vandalism, or storm damage.
M–P Auto Insurance Terms
Medical Payments Coverage
Medical payments coverage may help pay medical expenses after a crash. It can apply regardless of fault, depending on the policy.
Minimum Coverage
Minimum coverage means the least insurance required by state law. It may not provide enough protection for every driver.
Named Driver
A named driver is a person specifically listed on the policy. The insurer may consider that person’s driving history when setting rates.
Named Insured
The named insured is the main person shown on the policy. This person usually has important rights and responsibilities under the contract.
No-Fault Insurance
No-fault insurance generally pays certain injury costs through your own insurer. Rules, benefits, and requirements differ among no-fault states.
Personal Injury Protection
Personal injury protection may pay certain medical and related expenses. It is commonly called PIP and depends heavily on state law.
Policy
A policy is the legal contract between the customer and insurer. It explains coverage, exclusions, limits, duties, and payment rules.
Policy Period
The policy period is the time when coverage remains active. Start and end dates appear on the declarations page.
Premium
The premium is the amount charged for insurance coverage. Insurers may offer monthly, semiannual, or annual payment options.
Property Damage Liability
Property damage liability may pay for damage you cause to someone’s property. This can include another vehicle, fence, building, or roadside object.
The Insurance Glossary can help you compare similar terms across insurers. However, similar coverage names may not provide identical protection.
Q–T Auto Insurance Terms
Quote
A quote is an estimated price for insurance coverage. The final premium may change after the insurer verifies your information.
Rental Reimbursement Coverage
Rental reimbursement coverage may help pay for temporary transportation after a covered loss. Daily and total payment limits usually apply.
Replacement Cost
Replacement cost is the amount needed to replace damaged property without subtracting depreciation. Auto policies do not always settle vehicle losses this way.
State Insurance Department
A state insurance department regulates insurers within that state. It may also provide consumer information and complaint assistance.
Total Loss
A total loss occurs when repair costs are considered too high. State rules and insurer methods help determine whether a vehicle is totaled.
Underinsured Motorist Coverage
Underinsured motorist coverage may help when an at-fault driver lacks enough insurance. Availability, limits, and rules differ by state.
Underwriting
Underwriting is the process insurers use to evaluate risk. Driving history, location, vehicle type, claims, and coverage choices may be considered.
U–Z Auto Insurance Terms
Uninsured Motorist Coverage
Uninsured motorist coverage may help after a crash with an uninsured driver. It can cover certain injuries or damage, depending on the policy.
Vehicle Identification Number
A vehicle identification number is a unique code assigned to a vehicle. It is often shortened to VIN.
Vehicle Use
Vehicle use describes how a car is normally driven. Common categories include commuting, pleasure, business, or delivery use.
