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

Liability coverage is the part of your auto insurance that covers medical bills, lost wages, and property damage when you are found responsible for an accident. It does not cover your own vehicle or your own injuries — that is what collision, comprehensive, and medical payments coverage do. Liability is what protects your personal assets if someone sues you after an accident you caused.

Every state except New Hampshire requires you to carry some minimum amount of liability coverage before you can legally drive. The minimums are low — often $25,000 per person and $50,000 per accident for bodily injury, plus $25,000 for property damage — but they are rarely enough to cover a serious accident. If you cause a crash that injures multiple people or damages an expensive vehicle, you can quickly exceed those limits and owe the difference out of your own pocket.

Key Takeaways

  • Liability coverage pays for the other person's medical bills, vehicle repairs, and legal costs if you cause an accident, but your state's minimum requirement is usually too low to protect your assets in a serious crash.
  • Bodily injury liability covers medical expenses and lost wages for people you injure; property damage liability covers damage to their vehicle or other property.
  • If you cause an accident and your liability limit is exceeded, you are personally responsible for the remaining costs, which can include wage garnishment and asset seizure.
  • Most insurance agents recommend carrying limits at least three to five times your state's minimum, and higher if you have significant savings or own a home.

How bodily injury and property damage liability work together

Liability coverage has two parts. Bodily injury liability pays for medical treatment, rehabilitation, lost income, and pain-and-suffering damages for people you injure. Property damage liability pays to repair or replace the other person's vehicle, fence, building, or other property you damage. Insurance companies list these as separate limits — for example, 25/50/25 means $25,000 per person for bodily injury, $50,000 total per accident for bodily injury, and $25,000 for property damage.

The bodily injury limits apply per person and per accident. If you hit two people and injure both, the per-person limit applies to each one separately, but the total you pay for both cannot exceed the per-accident limit. Property damage has only one limit — the total you will pay for all property damage in that accident.

Your insurance company pays the claim first, then defends you in court if the other person sues. Once your liability limit is exhausted, the insurance company stops paying, and you are responsible for anything beyond that amount. This is why the difference between a $50,000 limit and a $300,000 limit can mean the difference between a manageable claim and financial ruin.

Why state minimums are not enough protection

State minimum liability limits exist to ensure every driver carries some coverage, not to ensure that coverage is adequate. A serious accident — one involving multiple injuries, a high-income earner, or permanent disability — can generate medical bills, lost-wage claims, and pain-and-suffering awards that easily exceed $100,000. A single person's lifetime medical care for a spinal injury or brain damage can run into the millions.

If your liability limit is $50,000 and the court awards $200,000 in damages, you owe the $150,000 difference. The other person's attorney can pursue wage garnishment, place a lien on your home, or seize your bank accounts to collect. This can continue for years or even decades in some states.

Insurance companies and financial advisors generally recommend carrying bodily injury limits of at least $100,000 per person and $300,000 per accident, with property damage of $100,000. If you have a home, savings, or a stable income, higher limits — $250,000 per person and $500,000 per accident — are often worth the small increase in premium.

What liability coverage does not pay for

Liability coverage does not cover damage to your own vehicle, medical bills for your own injuries, or lost wages if you cannot work because of your injuries. Those are covered by collision coverage (for crash damage to your car), comprehensive coverage (for theft, weather, and vandalism), and medical payments coverage or personal injury protection (for your own medical bills regardless of fault).

Liability also does not cover intentional damage, criminal acts, or accidents that happen while you are using your car for commercial purposes — such as rideshare driving or food delivery — unless you have added commercial coverage. It does not cover damage caused by a mechanical failure you knew about and ignored, though this is rarely an issue in practice because insurers almost always pay and then investigate.

If you cause an accident while driving under the influence, your insurance will still pay the liability claim, but the insurance company may drop you afterward, and you will face criminal charges separately. Liability coverage is separate from legal defense for criminal matters.

How your premium changes based on liability limits

Increasing your liability limits usually costs far less than most drivers expect. Moving from your state's minimum to $100,000 per person and $300,000 per accident might add $10 to $30 per month to your premium, depending on your age, driving record, location, and the insurance company. Moving to $250,000 and $500,000 might add another $10 to $20 per month.

The cost difference is small because serious accidents are rare, and the insurance company's risk of paying out a large claim is low. The real expense for the insurer is in handling claims and defending lawsuits, not in the size of the payout itself. This is why the jump from $50,000 to $100,000 costs less than you might think, but the jump from $100,000 to $1,000,000 costs proportionally more.

Some insurers offer umbrella coverage as a separate policy that sits on top of your auto liability limits. An umbrella policy with $1,000,000 in coverage typically costs $150 to $300 per year and kicks in only after your auto liability limit is exhausted. This is a cost-effective way to get high protection if you own a home or have significant assets.

What happens if you cause an accident and your limit is exceeded

When you cause an accident, the other person files a claim with your insurance company. Your insurer investigates, determines fault, and pays up to your liability limit. If the damages exceed your limit, the other person's attorney will typically send you a demand letter asking you to pay the difference. If you cannot pay, they can file a lawsuit against you personally.

If the court rules against you, a judgment is entered on your record. The other person can then use that judgment to garnish your wages, place a lien on your home, or seize bank accounts. The timeline and methods vary by state, but the process can continue for many years. Some states allow wage garnishment of 25 percent of your disposable income, and liens on property can prevent you from selling or refinancing your home.

This is why carrying adequate liability limits is not optional if you have assets to protect. The cost of higher limits is negligible compared to the cost of a judgment against you.

How to choose the right liability limits for your situation

Start by assessing your assets. If you rent, have little savings, and earn a modest income, your state's minimum might be acceptable — though $50,000 is still risky. If you own a home, have a 401(k) or savings account, or earn a stable income, you have assets worth protecting, and higher limits make sense.

Consider your driving habits and risk factors. If you drive frequently, commute in heavy traffic, or have a history of accidents or violations, higher limits reduce your exposure. If you drive rarely and in light traffic, your accident risk is lower, but the cost of higher limits is still small enough that it is worth carrying them.

Talk to your insurance agent about your specific situation. They can tell you what limits are common in your area, what your premium would be at different levels, and whether an umbrella policy makes sense for you. Many agents recommend at least $100,000 per person and $300,000 per accident as a baseline, with higher limits if you own a home.

Frequently Asked Questions

Does my liability coverage pay if someone else was partially at fault?

Yes. Your insurance pays based on the degree of fault assigned to you, not on whether the other person was also negligent. In a state that uses comparative negligence, if you are found 60 percent at fault and the damages are $100,000, your insurance pays $60,000. The other person's own insurance covers their share of their damages.

What if I hit a parked car and do not know who owns it?

Your liability coverage still applies. Report the accident to your insurance company and leave a note on the parked car with your contact information and policy number. Your insurer will handle the claim when the owner contacts them. If you leave the scene without reporting it, you may face hit-and-run charges in addition to the insurance claim.

Does liability coverage apply if someone is injured in my car but I was not in an accident?

No. If a passenger is injured because you swerved to avoid an obstacle, or if someone is injured while getting in or out of your car, that is typically covered by medical payments coverage or personal injury protection, not liability. Liability applies only when you cause damage or injury to someone else's person or property.

Can my liability coverage be denied if the accident was my fault?

Your insurance company cannot deny a claim simply because you were at fault — that is the entire point of liability coverage. However, they can deny a claim if you were committing a crime, driving without a valid license, or using your car for an excluded purpose like commercial delivery without commercial coverage.

What is the difference between liability and uninsured motorist coverage?

Liability covers damage you cause to others. Uninsured motorist coverage covers damage caused to you by a driver who has no insurance. These are separate protections, and you need both. Uninsured motorist is optional in most states but strongly recommended.
