What Liability Coverage Does in Your Car Insurance Policy

Liability coverage pays for damage or injuries you cause to someone else in a car accident

Liability coverage is the part of your car insurance that covers medical bills, vehicle repairs, and other costs when you are found responsible for an accident. It does not cover damage to your own car or injuries to you — that is what collision, comprehensive, and medical payments coverage do. Liability is the foundation of most car insurance policies because it protects the other person, and in most states, you are required by law to carry it.

Liability coverage has two parts: bodily injury liability and property damage liability. Bodily injury liability pays for medical treatment, lost wages, and pain-and-suffering claims when you injure someone else. Property damage liability pays to repair or replace the other person's vehicle, fence, building, or other property you damaged. Your insurance company will defend you in court if the other person sues, and will pay any settlement or judgment up to your policy limit.

Key Takeaways

• Liability coverage pays for injuries and property damage you cause to others, not damage to your own vehicle or injuries to yourself.
• Every state except New Hampshire requires you to carry some minimum amount of liability coverage, though the minimum varies by state.
• Your policy limit is the maximum your insurance will pay for one accident, so choosing a limit higher than your state's minimum protects your personal assets if the damages are large.
• If you cause an accident and your liability limit is too low, you may be personally responsible for the difference between what your insurance pays and what the other person is owed.

How bodily injury liability works

Bodily injury liability covers medical expenses for anyone injured in an accident you cause — the other driver, their passengers, pedestrians, or cyclists. This includes hospital bills, emergency room visits, surgery, physical therapy, and ongoing treatment. It also covers lost wages if the injured person cannot work during recovery, and pain-and-suffering damages if the case goes to court.

Your insurance company will typically handle communication with the injured person and their medical providers. If the injury claim is small, the other person's insurance may settle directly with your insurer. If the claim is large or disputed, the other person may hire a lawyer and sue you. Your insurance company will provide a lawyer to defend you and will pay any judgment up to your policy limit.

How property damage liability works

Property damage liability covers repairs or replacement of the other person's vehicle and any other property you damaged in the accident. This includes their car, motorcycle, truck, or any vehicle you hit. It also covers damage to buildings, fences, utility poles, street signs, or other structures.

The insurance company will typically get repair estimates from body shops and pay the reasonable cost to fix or replace the damaged property. If the other person's vehicle is totaled, your property damage liability will pay its fair market value. You do not get to choose the repair shop — the other person can take their vehicle to any shop they want, and your insurance pays the bill as long as the cost is reasonable.

State minimum liability limits and why they matter

Every state except New Hampshire requires drivers to carry liability coverage. The minimum amount varies by state. A common format is written as three numbers, like 25/50/25, which means $25,000 per person for bodily injury, $50,000 total per accident for bodily injury, and $25,000 for property damage. Some states use different minimums — for example, Florida requires 10/20/10, while California requires 15/30/5. Your state's Department of Motor Vehicles or insurance commissioner's office publishes the exact minimum for your state.

The state minimum is the least you can legally carry, but it is often not enough. A serious injury can cost far more than $25,000 in medical bills alone, and a lawsuit can award much more for pain and suffering. If you cause an accident and your liability limit is $25,000 but the injured person's damages total $100,000, your insurance pays $25,000 and you are personally responsible for the remaining $75,000. The other person can sue you directly, garnish your wages, or place a lien on your home to collect.

Choosing a liability limit higher than your state's minimum

Many insurance companies offer liability limits of $100,000, $250,000, $500,000, or $1,000,000 per accident. The cost to raise your limit from the state minimum to $100,000 or $250,000 is usually modest — often $10 to $30 per year. A higher limit protects your personal assets if you cause a serious accident.

Financial advisors often recommend carrying liability limits equal to your net worth or higher. If you own a home, have savings, or earn a good income, a judgment against you could take those assets. A $300,000 liability limit costs little more than the state minimum but covers most accidents that do not involve permanent disability or death. If you have significant assets, a $500,000 or $1,000,000 limit is worth the small additional premium.

What liability coverage does not cover

Liability coverage does not pay for damage to your own vehicle — that is collision coverage. It does not pay for your own medical bills — that is medical payments coverage or personal injury protection. It does not cover theft, weather, or vandalism to your car — that is comprehensive coverage. And it does not cover injuries to you or your household members in an accident you cause.

Liability also does not cover intentional damage. If you deliberately hit someone's car or property, your insurance will deny the claim. It also does not cover business use of your vehicle — if you use your car for rideshare, delivery, or other commercial work, you need commercial auto insurance in addition to your personal policy.

What happens if you cause an accident without enough liability coverage

If you cause an accident and your liability limit is lower than the damages, you are personally responsible for the difference. The other person can sue you in small claims court (for amounts under a few thousand dollars) or civil court. If they win, the court issues a judgment against you. The other person can then use that judgment to garnish your wages, seize your bank accounts, or place a lien on your home or other property.

Some states allow wage garnishment for a set number of years — often 10 to 20 years — so a judgment can follow you for decades. This is why carrying a liability limit higher than your state's minimum is important. The extra cost is small compared to the risk of losing your home or having your wages garnished.

Frequently Asked Questions

Does liability coverage pay for my own car repairs?

No. Liability covers damage you cause to someone else's property, not your own vehicle. If you cause an accident and your car is damaged, you need collision coverage to pay for repairs. If you do not have collision coverage, you pay for repairs yourself.

What if the other driver was partially at fault?

Most states use comparative fault rules. If you are found 70 percent at fault and the other driver 30 percent at fault, your liability coverage pays 70 percent of their damages. Some states use different rules — a few states bar you from recovering anything if you are more than 50 percent at fault. Your insurance company handles this calculation.

Can my liability coverage be canceled if I cause an accident?

Your insurance company can cancel your policy for non-payment or fraud, but not straightforward because you had an accident. However, your premium will likely increase at renewal. If you cause multiple accidents in a short time, your insurer may choose not to renew your policy when it expires.

What is an umbrella policy?

An umbrella policy is extra liability coverage that sits on top of your car insurance. If you cause an accident and your car insurance liability limit is exhausted, your umbrella policy covers the remaining damages up to its limit — typically $1,000,000 or more. Umbrella policies are inexpensive and useful if you have significant assets to protect.

Do I need liability coverage if I own my car outright?

Yes. Liability is required by law in almost every state, regardless of whether you own your car or owe money on it. Even if you own your car outright, you are legally required to carry at least your state's minimum liability coverage to drive on public roads.
