Liability car insurance is the most basic type of auto coverage, and in almost every U.S. state it is the one you are legally required to carry. It pays for the injuries and property damage you cause to other people when you are at fault in an accident. This guide explains what liability car insurance covers, what it does not, how coverage limits work, and how to pick the right amount.
What Is Liability Car Insurance?
Liability car insurance covers damages and injuries you cause to other people in an accident that is your fault. It does not pay for your own car or your own medical bills. Its job is to protect your savings, home, and future income from being used to pay someone else’s costs. If you are not sure how a deductible fits in with other coverages, see our guide on what a deductible in car insurance is.
Two Types of Liability Coverage
Bodily Injury Liability (BIL)
Bodily injury liability helps pay for the medical expenses, rehabilitation, lost wages, and legal costs of people hurt in an accident you caused. It also helps protect you if you are sued.
Property Damage Liability (PDL)
Property damage liability pays to repair or replace other people’s property that you damage, such as their vehicle, a fence, a building, or a traffic sign.
Why Liability Car Insurance Is Important
- It is a legal requirement. Most states require minimum liability coverage. Driving without it can mean fines, license suspension, or other penalties.
- It provides financial protection. If you are at fault, liability insurance helps cover the other party’s repairs, medical bills, and legal expenses.
- It protects your assets. Without it, you could be personally responsible for costs that exceed what you can afford, putting savings and property at risk.
- It gives peace of mind. You can drive knowing a serious accident will not automatically become a financial disaster.
How Liability Coverage Limits Work
Liability limits are usually written as three numbers, for example 25/50/25. The first number is the maximum (in thousands of dollars) paid for bodily injury per person, the second is the maximum bodily injury payout per accident, and the third is the maximum for property damage. With 25/50/25, the policy would pay up to $25,000 per injured person, $50,000 total for injuries in one accident, and $25,000 for property damage. Anything above those limits becomes your responsibility.
State minimums are often low compared with the real cost of a serious crash, so many drivers choose higher limits. Compare costs in our guide to how much car insurance costs per month, and read why people buy insurance to understand the bigger picture.
What Liability Insurance Does Not Cover
- Repairs to your own car (that needs collision or comprehensive coverage)
- Your own medical bills (that needs medical payments or personal injury protection)
- Damage you cause on purpose, or accidents covered by policy exclusions
If your car is declared a total loss, liability alone will not help you. See how to get the most money for a totaled car. And if someone else drives your car and causes a crash, read what happens if someone wrecks your car and they aren’t on your insurance.
How to Choose the Right Liability Limits
- Add up your assets (savings, home equity, investments) and consider coverage that protects them.
- Do not stop at the state minimum if you can afford more.
- Get quotes from several insurers and compare the same limits side by side.
- Ask about an umbrella policy if your assets are substantial.
Frequently Asked Questions
Is liability insurance enough?
It satisfies the legal requirement in most states, but it will not repair your own car or pay your own medical bills. Many drivers add collision and comprehensive coverage, especially if they are still financing a car.
Does liability insurance cover the other driver if they are at fault?
No. Liability covers damage you cause. If the other driver is at fault, their insurer should pay, or your uninsured motorist coverage may apply.
