What does liability insurance cover? Liability car insurance explained

What does liability insurance cover?

Liability coverage is the part of an auto insurance policy that protects other people from you, and protects you from the bills and lawsuits that follow when you are at fault. It has two parts, and each has its own limit.

Bodily injury liability

Bodily injury liability pays when you cause a crash that hurts or kills someone else. That can include the other driver, their passengers, pedestrians and cyclists. The Insurance Information Institute (Triple-I) lists it among the core coverages of a basic policy and says it applies to the drivers listed on your policy. Family members listed on the policy are also covered when they drive someone else's car with permission.

The money typically goes toward the injured person's medical bills, lost income and other damages they can claim from you. If the injured person sues, the claim is made against your liability coverage.

Property damage liability

Property damage liability pays for damage you cause to things that belong to other people. Most often that is the other car, but it also covers fences, buildings, mailboxes, utility poles and similar property. The Triple-I describes it as covering damage caused by you or by another person driving your car with your permission.

What liability does not cover

Liability coverage never pays for your own losses. It leaves out:

• Repairs to your own car after a crash, which is what collision coverage is for.
• Theft, hail, flood or fire damage to your car, which falls under comprehensive coverage.
• Your own medical bills and your passengers' bills, which personal injury protection or medical payments coverage can pay.
• Injuries caused by a driver with no insurance or too little, which uninsured motorist coverage handles.
• Anything above your limits. Once the policy has paid its maximum, the rest is your responsibility.

How split limits like 25/50/25 work

Liability limits are usually written as three numbers separated by slashes, in thousands of dollars. The California Department of Insurance explains the order this way:

1. The first number is the most the policy pays for injuries to any one person.
2. The second number is the most it pays for injuries to everyone hurt in one accident.
3. The third number is the most it pays for damage to other people's property in one accident.

So California's minimum of $30,000 / $60,000 / $15,000 is written 30/60/15, and Texas's $30,000 / $60,000 / $25,000 is what the Texas Department of Insurance calls 30/60/25 coverage.

A few states add wrinkles. New York's minimum is written 25/50/10, but the law sets higher limits when someone dies: $50,000 for one death and $100,000 for two or more. Some insurers also sell a combined single limit, one total that covers injuries and property together. Maine, for example, accepts a combined single limit of $125,000 in place of its split limits.

Worked example: a crash that goes over 25/50/25

Example: you carry 25/50/25 limits and cause a crash that injures three people and damages a car and a fence. The figures below are hypothetical and chosen only to show the arithmetic.

Two caps bite here. The driver's $40,000 bill is cut to $25,000 by the per-person limit. Then the three injury payments, which add up to $55,000 after that cut, are held to $50,000 by the per-accident limit. Property damage is capped separately at $25,000. In total the policy pays $75,000, and $30,000 of the $105,000 in damages is left for you to pay.

For example, the same crash under 100/300/100 limits would be paid in full, because no single injury tops $100,000, the injuries together stay under $300,000 and the property damage stays under $100,000.

State minimum liability limits compared

Every state sets its own floor. The table shows the minimums for states whose figures we checked directly against the state regulator or statute. Use the state minimums tool to look up other states.

New Hampshire is the one state that does not require a policy. Instead you must be able to show you can pay for damage you cause, and any policy you do buy has to meet the limits above. New Jersey also sells a stripped-down Basic Policy with only $5,000 of property damage liability and no bodily injury liability unless you add it.

Why state minimums are low compared with real crash costs

State minimums are set by lawmakers and change only when a law changes. Massachusetts, for example, raised its bodily injury and property damage minimums in July 2025. Repair and medical costs keep moving in the meantime, and several regulators warn that minimum limits can run out quickly:

• The Texas Department of Insurance notes that the minimum may not be enough if you hurt several people or total someone's car, and that you could owe the difference and be sued for it.
• The National Association of Insurance Commissioners (NAIC) says in its consumer guide that state minimums are too low to fully protect you if you cause a serious accident.
• The Triple-I recommends buying more than the state minimum, enough to protect assets such as your home and savings.

The national figures point the same way. The NAIC found the average collision claim, the cost of repairing an insured car, was $7,191 in 2022, up 17.6% in a year. That single average claim is most of New York's $10,000 or Florida's $10,000 property damage minimum, and a newer car or a multi-car crash can cost far more. Insurers paid $120.5 billion in liability losses nationwide in 2022, and liability premiums grew 19% over 2019-2023.

How to choose your liability limits

There is no single right number, because the point of liability coverage is to protect what you have and what you will earn. A simple way to work through it:

1. Look up your state's minimum with the state minimums tool, so you know the floor.
2. Add up what a lawsuit could reach: savings, home equity, investments outside retirement accounts and future wages.
3. Ask an agent or insurer to quote several limit levels side by side, for example the minimum, a middle option and a high option.
4. Compare the extra yearly cost of each step up with how much more protection it buys.
5. If your assets exceed the highest auto limits you can buy, ask about an umbrella policy. The Triple-I says umbrella coverage pays once your underlying limits are used up and typically costs $200 to $300 a year for $1,000,000 of coverage.
6. Check that your uninsured motorist coverage keeps pace, since in several states it is tied to your liability limits.

Liability insurance in no-fault states

In the 12 states with no-fault laws, each driver's own personal injury protection pays their medical bills first, whoever caused the crash. Liability coverage still matters there. It pays for damage you do to other people's property, and it responds when an injured person meets the state's threshold for a serious injury and sues you. Florida is unusual: its registration rules require PIP and property damage liability, but not bodily injury liability for ordinary passenger vehicles. Drivers there can add it if they want that protection.

Liability is also the core of a "liability-only" policy, which meets the legal requirement in most states but leaves out collision and comprehensive. Whether that trade-off makes sense depends mostly on your car's value, which our guide to full coverage car insurance walks through.
