What Liability Coverage Does in Your Car Insurance Policy

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

Liability coverage is the part of your car insurance that covers the other person's medical bills, vehicle repairs, or property damage if you're found responsible for an accident. It does not cover your own injuries or your own car. Most states require you to carry it, and your lender will require it if you have a loan or lease on your vehicle.

Liability coverage has two parts: bodily injury liability, which covers medical expenses and lost wages for people you injure, and property damage liability, which covers damage to someone else's vehicle, fence, building, or other property. You choose how much coverage you want in each category, and those limits determine the maximum the insurance company will pay.

If you cause an accident and the other person sues you, your insurance company will defend you in court and pay the settlement or judgment up to your policy limits. If the damages exceed your limits, you may be responsible for the difference.

Key Takeaways

• Liability coverage pays for injuries and property damage you cause to others, not damage to your own vehicle or injuries to yourself.
• You choose your coverage limits (for example, $25,000 per person for bodily injury), and the insurance company pays up to that amount.
• Most states legally require minimum liability coverage, and lenders require it on financed or leased vehicles.
• If damages exceed your policy limits, you may be personally responsible for the remaining costs.
• Liability coverage includes legal defense costs if the other person sues you.

How liability limits work and what the numbers mean

Liability limits are written as three numbers, like 25/50/25. The first number is the bodily injury limit per person, the second is the bodily injury limit per accident, and the third is the property damage limit per accident. So 25/50/25 means the insurance company will pay up to $25,000 for one person's injuries, up to $50,000 total for all injuries in one accident, and up to $25,000 for property damage.

Each state sets a minimum liability requirement. Some states require as little as 15/30/5 (meaning $15,000 per person, $30,000 per accident for injuries, and $5,000 for property damage). Other states require higher minimums. You can carry more than the minimum, and many people do because medical bills and vehicle repairs often exceed state minimums.

If you cause an accident that injures three people and each person's medical bills are $30,000, a 25/50/25 policy would pay $25,000 to each of the first two people and $0 to the third person, because the per-accident limit of $50,000 is reached. The third person could sue you personally for the remaining $30,000.

Bodily injury liability versus property damage liability

Bodily injury liability covers medical treatment, surgery, hospital stays, rehabilitation, lost wages, and pain and suffering for people you injure. It also covers funeral expenses if someone dies. The coverage applies whether the injured person is in another vehicle, a pedestrian, or a cyclist.

Property damage liability covers repairs or replacement of the other person's vehicle, their home, a fence, a mailbox, a storefront, or any other property you damage. It does not cover your own property or your own vehicle, even if you hit something stationary like a pole or a parked car.

You set these two limits independently. Some people choose higher bodily injury limits because medical costs are unpredictable and can be very high, while keeping property damage limits lower. Others do the reverse. Your choice depends on your assets and how much risk you want to carry yourself.

What liability coverage does not cover

Liability coverage does not pay for damage to your own vehicle, no matter who caused the accident. If you hit another car and your bumper is damaged, your liability coverage will pay for the other car's damage but not yours. To cover your own vehicle, you need collision coverage or comprehensive coverage, which are separate add-ons.

Liability coverage does not cover your own medical bills or lost wages if you are injured in an accident you caused. For that, you need medical payments coverage or personal injury protection, depending on your state and policy.

Liability coverage also does not explore if you intentionally cause damage, if you are driving someone else's car without permission, or if you are using your vehicle for commercial purposes like rideshare or delivery (unless you have a commercial auto policy). Some policies exclude coverage for racing or off-road driving.

State minimum liability requirements and why they vary

Every state except New Hampshire requires drivers to carry liability insurance or post a bond. The minimum amounts vary widely. Some states require 15/30/5, others require 25/50/25, and a few require higher amounts. You can look up your state's requirement on your state's insurance commissioner website or ask your insurance agent.

Minimum requirements exist because legislatures want to may support that if you cause an accident, the other person has some way to recover costs. However, minimums are often too low to cover serious injuries. A single hospitalization can easily cost $100,000 or more, so carrying only the state minimum leaves you exposed to a lawsuit for the difference.

If you do not carry the required liability coverage in your state, you can face fines, license suspension, vehicle registration suspension, or court-ordered SR-22 filing (a document proving you have insurance). The penalties vary by state and by how long you drove uninsured.

How liability coverage pays out after an accident

After an accident, you report it to your insurance company. The company assigns a claims adjuster who investigates the accident, reviews police reports, interviews witnesses, and examines vehicle damage to determine who was at fault. If you are found at fault, the adjuster works with the other person's insurance company or attorney to settle the claim.

If the other person's damages are within your policy limits, your insurance company pays the claim directly. If the damages exceed your limits, your insurance company pays up to your limit, and you are responsible for the rest. The other person can sue you in small claims court or civil court to recover the difference, and they can garnish your wages or place a lien on your home or other assets.

Your insurance company also pays for your legal defense if the other person sues you. This includes attorney fees, court costs, and settlement negotiations. The defense is provided at no extra cost to you as part of your liability coverage.

Umbrella insurance and when it makes sense

Umbrella insurance is a separate policy that covers liability claims above your auto insurance limits. For example, if you have 100/300/100 auto liability coverage and you cause an accident that results in $500,000 in damages, your auto policy pays $300,000 and your umbrella policy pays the remaining $200,000 (up to your umbrella limit).

Umbrella policies typically start at $1 million in coverage and cost $150 to $300 per year. They cover not only car accidents but also liability claims from your home (like someone injured on your property) and other sources. Umbrella insurance makes sense if you have significant assets to protect, if you cause an accident that could result in a large judgment, or if you want extra peace of mind.

To buy umbrella insurance, you usually need to carry higher auto liability limits first — often 250/500/100 or higher. Your insurance agent can explain whether umbrella coverage makes sense for your situation.

Frequently Asked Questions

Does liability coverage pay for my own injuries if I cause an accident?

No. Liability coverage only pays for the other person's injuries and property damage. Your own medical bills are covered by medical payments coverage or personal injury protection, which you must add separately. If you cause an accident and are injured, you would need to file a claim under your own coverage, not the liability portion.

What happens if I cause an accident and don't have liability insurance?

You become personally responsible for all damages. The other person can sue you for medical bills, vehicle repairs, lost wages, and pain and suffering. If they win a judgment, they can garnish your wages, place a lien on your home, or seize other assets. You also face state penalties including fines, license suspension, and mandatory SR-22 filing.

Can I choose my liability limits, or does my state set them?

Your state sets the minimum, but you can choose to carry more. Most states allow you to select from several limit options. Carrying more than the minimum is common because state minimums often do not cover serious injuries or major property damage. Your insurance agent can help you choose limits that match your assets and risk tolerance.

Does liability coverage explore if someone else is driving my car?

Yes, as long as they have your permission. Your liability coverage follows the vehicle, not the driver. If a friend borrows your car and causes an accident, your liability insurance pays for the other person's damages. However, if someone steals your car or drives it without permission, your liability coverage does not explore.

What's the difference between liability coverage and collision coverage?

Liability pays for damage you cause to someone else. Collision pays for damage to your own vehicle from hitting another car or object. Property damage liability covers the other car; collision covers yours. You need both if you want full protection for your vehicle, though only liability is required by law.
