Auto insurance coverage types explained
Liability, collision, comprehensive and uninsured-motorist coverage do different jobs. State minimums vary, so check your state.

- Liability coverage pays for injuries and damage you cause to others; collision and comprehensive cover your own car.
- Most states require minimum liability coverage, and the amount varies.
- Higher liability limits protect your assets; a higher deductible usually lowers the premium.
- Lenders usually require collision and comprehensive on financed or leased cars.
What each coverage does
| Coverage | What it pays for |
|---|---|
| Bodily injury liability | Injuries you cause to other people |
| Property damage liability | Damage you cause to someone else’s car or property |
| Collision | Damage to your car from a collision with another car or object |
| Comprehensive | Damage to your car not caused by a collision — for example theft, hail, fire, flood or hitting an animal |
| Uninsured / underinsured motorist | Your costs when a driver with no or too little insurance (or a hit-and-run driver) hits you |
State rules differ
Most states require drivers to carry a minimum amount of liability coverage, and the amount varies by state. Each state also uses either a tort system or a no-fault system, which affects what coverage is available. Check your state department of insurance for the rules that apply to you.
Choosing limits and deductibles
- Minimum limits may not cover a serious accident; higher liability limits protect your assets.
- A higher deductible usually lowers the premium but raises what you pay after a claim.
- If you lease or finance a car, the lender usually requires collision and comprehensive.
