Liability coverage pays for damage or injury you cause to someone else in an accident — not damage to your own car

Liability insurance is the part of your car insurance that covers medical bills, lost wages, and property damage when you're found responsible for an accident. It pays the other person's costs, not yours. If you hit another car and injure the driver, liability covers their hospital bills and their car repair. It does not cover your own injuries or your own vehicle damage — that's what collision and comprehensive coverage do.

Every state except New Hampshire requires you to carry liability insurance before you can legally drive. The amount you're required to carry varies by state, but most states set a minimum of around $25,000 per person injured and $50,000 per accident. Those minimums are often too low to cover serious injuries or multiple people, which is why many people carry higher limits.

Liability coverage has two parts: bodily injury liability (which covers medical expenses and lost income for people you injure) and property damage liability (which covers damage to other people's vehicles, buildings, or other property). Your insurance company will defend you in court if someone sues, and will pay any judgment up to your policy limit.

Key Takeaways

  • Liability insurance 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 liability coverage, though minimum amounts vary — most states require at least $25,000 per person and $50,000 per accident.
  • Liability has two parts: bodily injury liability (medical bills and lost wages for injured people) and property damage liability (damage to other vehicles or property).
  • Your insurance company will pay claims and defend you in court up to your policy limit, but you pay anything above that limit out of pocket.
  • Higher liability limits cost relatively little more per month but protect you from catastrophic financial loss if you cause a serious accident.

How bodily injury liability works

Bodily injury liability covers medical treatment, rehabilitation, lost wages, and pain and suffering for anyone injured in an accident you cause. If you hit a pedestrian, this coverage pays for their emergency room visit, surgery, physical therapy, and any income they lose while recovering. It also covers passengers in the other vehicle and, in some cases, passengers in your own vehicle if you're found at fault.

The insurance company will investigate the accident, determine fault, and negotiate a settlement with the injured person or their lawyer. If they can't agree on a settlement amount, the injured person can sue you, and your insurance company will pay for your legal defense and any judgment up to your policy limit. If the judgment exceeds your limit, you are responsible for the difference.

Bodily injury limits are written as two numbers: the per-person limit and the per-accident limit. A policy with $50,000/$100,000 limits means the insurance company will pay up to $50,000 for any one person's injuries and up to $100,000 total for all injuries in a single accident. If you injure three people and the total medical bills are $150,000, the insurance pays $100,000 and you owe $50,000.

How property damage liability works

Property damage liability covers damage to other people's vehicles, buildings, fences, utility poles, and other property you damage in an accident. If you back into someone's parked car, this coverage pays for their repairs. If you lose control and hit a storefront, it pays for the building damage. It does not cover your own vehicle — that's collision coverage.

Property damage claims are usually simpler than bodily injury claims because the damage is concrete and measurable. The insurance company gets repair estimates, pays the other person's repair shop directly, or reimburses them for repairs already completed. Property damage limits are typically a single number — $25,000, $50,000, or $100,000 — representing the maximum the insurance company will pay per accident.

Property damage liability also covers damage you cause while driving someone else's car with permission. If you borrow a friend's car and cause an accident, your liability coverage (not theirs) is primary, and their coverage is secondary. This is why it's important to tell your insurance company about regular borrowing — some policies exclude occasional drivers.

What liability insurance does not cover

Liability insurance does not cover damage to your own vehicle, medical bills for your own injuries, or lost wages from your own recovery. If you cause an accident, your own collision coverage pays for your car repairs, and your own medical payments coverage (if you have it) or health insurance pays for your injuries. Liability is strictly for the other person's losses.

Liability also does not cover intentional damage, criminal acts, or accidents that happen while you're using your car for commercial purposes (like delivery driving or rideshare). If your policy excludes commercial use and you cause an accident while working for a delivery app, the insurance company may deny the claim. Some insurers offer commercial or rideshare endorsements that extend liability to those uses.

Liability does not cover uninsured or underinsured motorists. If someone without insurance hits you, your uninsured motorist coverage pays for your injuries and car damage — not their liability coverage, because they don't have any. Uninsured and underinsured motorist coverage is separate from liability and is required in most states.

Minimum liability limits versus higher limits

State minimum liability limits are often too low to cover serious accidents. A $25,000 bodily injury limit sounds like a lot until someone spends three days in the hospital — emergency care, surgery, and imaging can easily exceed that in a single day. A serious injury with long-term care, lost wages, and pain and suffering can cost hundreds of thousands of dollars. If your policy limit is $25,000 and the judgment is $200,000, you owe the remaining $175,000 out of pocket.

Increasing your liability limits from the state minimum to $100,000/$300,000 or $250,000/$500,000 typically costs $10 to $30 more per month, depending on your age, driving record, and location. That small increase in premium protects you from losing your savings, home, or future wages in a lawsuit. Many insurance agents recommend carrying limits at least equal to your net worth, and higher if you have significant assets.

Umbrella insurance is another option if you have substantial assets. An umbrella policy sits on top of your car and home liability coverage and covers claims that exceed those limits. A $1 million umbrella policy typically costs $150 to $300 per year and protects you if you cause a catastrophic accident.

How fault is determined and who pays

Liability insurance only pays if you are found at fault for the accident. Fault is determined by police reports, witness statements, traffic laws, and sometimes accident reconstruction. In some states, fault is all-or-nothing: you're either responsible or you're not. In other states, comparative fault allows both drivers to share responsibility — if you're found 30% at fault and the other driver 70% at fault, your liability insurance pays 30% of their damages.

Your insurance company will not pay a claim if you're not at fault. If the other driver caused the accident, their liability insurance should pay for your damages. If they don't have insurance or their insurance denies the claim, you would use your own uninsured or underinsured motorist coverage. This is why having both liability and uninsured motorist coverage is important — liability protects you when you cause an accident, and uninsured motorist protects you when someone else causes one.

If you're found partially at fault in a comparative fault state, your liability insurance still pays the other person's damages up to your limit, but your own collision coverage will not pay for your vehicle damage (because you were partially responsible). You may have to pay your collision deductible out of pocket.

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 injured person or their lawyer can sue you for the full amount, and a court judgment can lead to wage garnishment, bank account levies, or a lien on your home. In some states, a judgment can follow you for 10 to 20 years.

If you cannot pay a judgment, the injured person may pursue collection through the court system. They can garnish your wages, seize money from your bank account, or place a lien on your home. Some states allow you to protect a certain amount of your wages or home equity from collection, but those protections are limited. A serious accident with multiple injured people can result in a judgment far larger than your assets.

This is why carrying liability limits higher than your state's minimum is important. The cost difference is small, but the protection is enormous. If you have significant assets, an umbrella policy is a relatively inexpensive way to protect them.

Frequently Asked Questions

Does liability insurance cover me if I'm driving someone else's car?

Your liability coverage typically follows you when you drive someone else's car with permission. Your policy is primary, and their policy is secondary. However, some policies exclude regular drivers or have restrictions on borrowed vehicles, so check your policy or call your insurance company to confirm.

What if the other person doesn't have insurance and I'm found at fault?

Your liability insurance still pays for their damages up to your limit. Your uninsured motorist coverage does not apply because you caused the accident. Uninsured motorist coverage only pays when someone without insurance hits you.

Can I be sued for more than my liability limit?

Yes. Your liability insurance pays up to your policy limit, but if the judgment is higher, you owe the difference. The injured person can pursue collection through wage garnishment, bank levies, or a lien on your home. This is why higher limits and umbrella insurance matter.

Does liability insurance cover damage to my own car?

No. Liability only covers damage you cause to other people's property and injuries to other people. Damage to your own vehicle is covered by collision insurance (if you have it). Your own medical bills are covered by medical payments coverage or your health insurance.

What's the difference between bodily injury and property damage liability?

Bodily injury liability covers medical bills and lost wages for people you injure. Property damage liability covers damage to other people's vehicles and property. Both are part of your liability coverage, and both have separate limits.
