Full Coverage vs. Liability Only: Which Do You Need?
What full coverage car insurance really includes, how it differs from liability-only, and how to decide which is right for your car.
Updated October 3, 2026 · 6 min read
Key takeaways
- Liability-only pays for damage and injuries you cause to others. It doesn't fix your own car.
- "Full coverage" usually means liability plus collision and comprehensive.
- Lenders and leasing companies require full coverage until the car is paid off.
- On an older, low-value car, liability-only can make financial sense.
What liability-only covers
Liability insurance pays for injuries and property damage you cause to other people. Nearly every state requires it. Limits are often written as three numbers, such as 100/300/100. That means $100,000 for injuries to one person, $300,000 for all injuries in one accident, and $100,000 for property damage.
Liability does not pay to repair or replace your own car, and it doesn't cover your car if it's stolen or damaged by weather.
What "full coverage" means
"Full coverage" isn't an official policy type. It's shorthand for a policy that includes:
- Liability for damage you cause to others
- Collision, which repairs your car after a crash, whatever the fault
- Comprehensive, which covers theft, hail, fire, flood, vandalism and hitting an animal
Many full-coverage policies also include uninsured motorist coverage and medical payments or personal injury protection, depending on the state.

When you need full coverage
- Your car is financed or leased. The lender will require it.
- You couldn't afford to repair or replace your car out of pocket.
- Your car is newer or worth more than a few thousand dollars.
When liability-only can make sense
- The car is paid off and worth relatively little.
- You have savings to replace it if it's totaled.
- The yearly cost of collision and comprehensive is more than roughly 10% of the car's value.
Even with liability-only, consider limits well above your state's minimum. A serious accident can easily exceed minimum limits, and you can be personally responsible for the difference.
Frequently asked questions
Does full coverage pay off my loan if my car is totaled?
It pays the car's actual cash value, which can be less than what you owe. Gap insurance covers that difference.
Is full coverage required by law?
No state requires collision or comprehensive. Lenders and lessors do.
Can I drop to liability-only after paying off my car?
Yes. Many drivers do once the car's value drops. Compare the savings with what you'd lose if the car were totaled.
