- Liability coverage generally addresses injuries or property damage you cause to others, subject to policy limits.
- Collision generally covers damage to the insured vehicle from a crash; comprehensive generally addresses many non-collision causes.
- State requirements vary, and a lender or lessor may require physical-damage coverage.
- Coverage names are not enough—compare limits, deductibles, exclusions and endorsements.
A plain-English guide to major auto insurance coverage categories and the questions to ask under your state’s rules. The examples below are explanatory, not product quotes or promises of approval, savings, coverage or investment performance.
Liability protects against claims by others
Bodily injury liability generally responds to covered injuries you cause, while property damage liability generally addresses covered damage to another person’s vehicle or property. Minimum requirements vary by state and may be far below the potential cost of a serious crash.
Physical damage to your own car
| Coverage | Generally addresses | Common limitation |
|---|---|---|
| Collision | Crash with another vehicle or object, or rollover | Deductible and vehicle value |
| Comprehensive | Theft, fire, weather, vandalism, animal impact and other listed non-collision events | Deductible and exclusions |
| Liability | Covered injury or damage caused to others | Policy limit; does not repair your own car |
The policy controls. “Full coverage” is marketing shorthand, not a standardized promise that every loss is covered.
Other coverage to ask about
- Uninsured and underinsured motorist coverage
- Medical payments or personal injury protection
- Rental reimbursement
- Roadside assistance and towing
- Gap coverage for a financed vehicle
Requirements and availability depend on state law and the insurer.

Use the guide for a documented decision
Before acting on Auto Insurance Coverage Types: Liability, Collision and Comprehensive, write down the facts that apply to your household: the current balance or coverage, the relevant deadline, the exact contract or account terms and the amount your budget can support. Then compare those facts with the official sources below and the latest documents from the institution, insurer, employer or government agency involved.
- Save the dated statement, disclosure, policy or plan document used in the comparison.
- Separate confirmed terms from estimates, marketing language and assumptions.
- Record the question that remains unresolved and who can answer it.
- Recheck the numbers after a rate, balance, income, law or household change.
