Car liability insurance pays for damage or injuries you cause to someone else in an accident

Liability insurance is the part of your car insurance that covers medical bills, lost wages, pain and suffering, and property damage when you are found responsible for an accident. It does not cover damage to your own vehicle — that is what collision and comprehensive coverage do. Most states require you to carry liability insurance before you can legally drive, and your lender will require it if you have a loan or lease on the car.

Liability comes in two pieces: bodily injury liability covers injuries to other people, and property damage liability covers damage to their vehicle or other property. When you buy a policy, you choose limits for each — typically written as numbers like 25/50/25, which means $25,000 per person for injuries, $50,000 total per accident for injuries, and $25,000 for property damage.

Key Takeaways

  • Liability insurance pays for injuries and property damage you cause to others, not damage to your own car.
  • Your state sets a minimum liability limit you must carry, but that minimum is often too low to protect your assets if you cause a serious accident.
  • If the damages exceed your policy limit, you can be sued personally for the difference, which can lead to wage garnishment or liens on your home.
  • Raising your limits from the state minimum to $100,000 or $300,000 costs relatively little but protects you from catastrophic financial loss.

State minimum liability limits and why they matter

Every state sets a minimum amount of liability insurance you must carry. These minimums vary widely — some states require as little as $15,000 per person for bodily injury, while others require $25,000 or more. You can find your state's requirement on your insurance declaration page or by calling your insurer, but the point is that the legal minimum is almost never enough.

A single serious accident can easily cost $100,000 or more in medical bills, lost income, and pain and suffering. If you cause that accident and your policy limit is only $25,000, the injured person can sue you personally for the remaining $75,000. That lawsuit can result in wage garnishment, a lien on your home, or a judgment that follows you for years. Liability insurance protects your personal assets — your savings, your house, your future income — by paying those claims up to your chosen limit.

Bodily injury liability versus property damage liability

Bodily injury liability covers medical expenses, rehabilitation, lost wages, and pain and suffering for people injured in an accident you cause. This includes passengers in the other vehicle, pedestrians, and cyclists. It does not cover you or your own passengers — that is what your medical payments coverage or uninsured motorist protection does. The first number in your policy limit (like the 25 in 25/50/25) is the per-person maximum, and the second number is the total maximum the insurer will pay for all injured people in one accident.

Property damage liability covers repairs or replacement of the other person's vehicle, fence, building, or other property you damage. It does not cover your own vehicle. This limit is usually lower than your bodily injury limit because vehicle damage alone is typically less expensive than injuries, though a single accident can still cause tens of thousands of dollars in damage.

What liability insurance does not cover

Liability insurance does not pay for damage to your own car, medical bills for you or your passengers, or injuries from uninsured drivers. If you hit a parked car and damage your own bumper, your liability coverage pays for the other car but not yours — you would need collision coverage for that. If you are injured in an accident you caused, your own medical payments coverage or health insurance pays your bills, not your liability policy.

Liability also does not cover intentional damage, criminal acts, or damage from racing or reckless driving in some policies. If you cause an accident while driving under the influence, your insurer may still pay the claim (because the other person is not at fault), but they can sue you to recover what they paid, and your rates will increase significantly.

How liability limits affect your premium and your risk

The higher your liability limits, the more you pay in premium, but the difference is usually smaller than people expect. Raising your limits from the state minimum (say, 25/50/25) to a more protective level (like 100/300/100) might add $10 to $30 per month to your bill, depending on your age, driving record, and location. Raising limits to $250,000 or $500,000 per person adds even less because the insurer's risk increases slowly once you are already well-protected.

The real trade-off is between a slightly higher premium now and the risk of losing your home or having your wages garnished later. Most financial advisors recommend carrying limits equal to your net worth or higher — if you own a house, have savings, or earn a decent income, the state minimum is not enough. An umbrella policy (also called excess liability) is a cheap way to add another $1 million in coverage on top of your car policy, usually for $150 to $300 per year.

How a liability claim works after an accident

After an accident, the other person may contact your insurance company or hire a lawyer. Your insurer will investigate the accident, determine whether you were at fault, and if so, negotiate a settlement with the other person or their lawyer. If the claim is within your policy limit, your insurer pays it and the case closes. You do not have to pay anything out of pocket (except your deductible, which only applies to collision or comprehensive claims, not liability).

If the claim exceeds your policy limit, your insurer pays up to the limit and stops. The injured person can then sue you personally for the rest. This is called a judgment against you, and it can result in wage garnishment, a lien on your home, or a bank account levy. Your insurer will not defend you in that lawsuit because you are no longer their customer — you are now the defendant. This is why carrying adequate limits matters so much.

Umbrella insurance as extra protection

An umbrella policy (or excess liability policy) sits on top of your car insurance and pays claims that exceed your car policy limits. If you cause an accident that results in a $500,000 judgment and your car policy limit is $100,000, your umbrella policy pays the remaining $400,000 (up to its limit, usually $1 million). Umbrella policies are inexpensive — typically $150 to $300 per year for $1 million in coverage — because they only pay when your underlying car policy is exhausted.

Umbrella policies also cover some claims that car insurance does not, such as libel, slander, or injuries on your property. If you own a home, have significant assets, or worry about being sued, an umbrella policy is one of the cheapest ways to protect yourself. You can buy one from the same insurer as your car policy or from a different company.

Frequently Asked Questions

Does liability insurance cover damage to my own car?

No. Liability insurance only covers damage you cause to someone else's vehicle or property. Damage to your own car is covered by collision insurance (if you hit another vehicle or object) or comprehensive insurance (if your car is stolen, vandalized, or damaged by weather). You choose whether to buy these coverages; they are not required by law.

What happens if I cause an accident and my liability limit is too low?

If the damages exceed your policy limit, the injured person can sue you personally for the difference. A judgment against you can result in wage garnishment, a lien on your home, or a bank levy. This is why carrying limits higher than your state's minimum is important — it protects your personal assets.

Can I be sued if I have liability insurance?

Yes, you can still be sued even with liability insurance. However, your insurer will defend you and pay the judgment up to your policy limit. If the judgment exceeds your limit, you are responsible for the rest. This is why adequate limits and umbrella coverage matter.

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

Your state requires it by law. If you have a loan or lease, your lender requires it as a condition of the loan. Even if neither applied, liability insurance protects your personal assets if you cause an accident, so it is worth carrying regardless.

How much liability insurance should I carry?

Most financial advisors recommend carrying limits equal to your net worth or higher. If you own a home or have savings, the state minimum is usually too low. A common recommendation is $100,000 per person and $300,000 per accident for bodily injury, plus $100,000 for property damage, with an umbrella policy for additional protection.
