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 costs when you are at fault in an accident. If you hit another car, injure a pedestrian, or damage someone's property with your vehicle, your liability coverage pays their medical bills, vehicle repairs, or property damage—up to the limits you chose when you bought your policy.
Every state except New Hampshire requires you to carry some minimum amount of liability coverage before you can legally drive. The state sets the floor; you can buy more. Your insurer will not pay anything for damage to your own vehicle or injuries to you under liability coverage—that is what collision and comprehensive coverage do. Liability only covers the other party.
Key Takeaways
- Liability coverage pays for the other person's medical bills, lost wages, pain and suffering, and vehicle repairs when you cause an accident.
- Every state sets a minimum liability limit you must carry, but that minimum is often too low to protect your own assets if you cause a serious accident.
- Liability has two parts: bodily injury liability (medical and wage costs) and property damage liability (vehicle and building damage).
- If the damage you cause exceeds your liability limit, you can be sued personally for the difference, which is why many people buy more than the state minimum.
Bodily injury liability covers medical costs and lost income
Bodily injury liability pays for injuries to people in the other vehicle, pedestrians, or cyclists you hit. This includes emergency room visits, surgery, hospital stays, physical therapy, and ongoing medical treatment. It also covers lost wages if the injured person cannot work during recovery, and pain and suffering damages awarded by a court or agreed to in a settlement.
The limit you choose appears as two numbers on your policy—for example, 100/300. The first number is the per-person limit (the most your insurer will pay to any one injured person), and the second is the per-accident limit (the most your insurer will pay total for all injuries in one accident). If you hit a car with four people and cause injuries totaling $400,000, a 100/300 policy would pay only $300,000 total, leaving you personally responsible for the remaining $100,000.
Property damage liability covers vehicle repairs and other damage
Property damage liability covers the cost to repair or replace the other person's vehicle, and also damage to their home, fence, mailbox, or any other property you damage with your car. If you back into a parked car and cause $8,000 in damage, your property damage liability pays it. If you lose control and hit a house, it pays for the repairs.
Property damage liability has a single limit—the maximum your insurer will pay for all property damage in one accident. Common limits are $25,000, $50,000, or $100,000. Unlike bodily injury, there is no per-person breakdown; the limit is a total pool. If you cause $60,000 in damage to two vehicles and a fence, and your limit is $50,000, you owe the remaining $10,000 out of pocket.
State minimums versus what you actually need
Every state sets a minimum liability limit you must carry to register your vehicle. These minimums vary widely. Some states require as little as 15/30/5 (meaning $15,000 per person, $30,000 per accident for bodily injury, and $5,000 for property damage). Others require 25/50/25 or higher. You can look up your state's requirement on your state insurance commissioner's website or ask your insurer.
The state minimum is a legal floor, not a safety recommendation. A serious accident—especially one involving multiple vehicles or a pedestrian—can easily generate medical bills and repair costs far above the minimum. If you cause $200,000 in damage and your policy limit is $50,000, the injured party can sue you personally for the remaining $150,000. That lawsuit can result in wage garnishment, a lien on your home, or a judgment that follows you for years. Many insurance agents recommend carrying at least 100/300/100 or higher, depending on your assets and income.
What liability coverage does not pay for
Liability coverage does not pay for damage to your own vehicle, injuries to you, or medical payments to your passengers. Those are covered by collision insurance (your vehicle damage), comprehensive insurance (theft, weather, vandalism), and medical payments coverage (your passengers' injuries). Liability also does not cover intentional damage—if you deliberately hit someone's car, your insurer will likely deny the claim and may cancel your policy.
Liability also does not cover criminal acts, violations of traffic laws that you caused on purpose, or accidents that happen while you are committing a crime. If you are driving under the influence and cause an accident, your insurer will still pay the other party's claim (because they are not at fault), but they may pursue a separate claim against you or cancel your policy after paying.
How a liability claim works after an accident
After an accident, you report it to your insurer. You provide your policy number, a description of what happened, the other driver's contact and insurance information, and the names and contact details of any witnesses. Your insurer assigns a claims adjuster to investigate. The adjuster may contact the other driver, review police reports, inspect vehicle damage, and gather medical records if injuries are involved.
If the other party's damages are clearly within your policy limit and liability is clear, your insurer will typically negotiate a settlement with the other driver's insurer or their attorney. If the other party is seriously injured or if liability is disputed, the process can take months. Your insurer will defend you in court if the other party sues, up to your policy limit. Once the claim is settled or a judgment is entered, your insurer pays the agreed amount or court award, and the claim closes.
Umbrella coverage for protection beyond your liability limit
Umbrella insurance is a separate policy that covers claims above your car insurance liability limits. If you cause a $500,000 accident and your car liability limit is $300,000, umbrella coverage kicks in and pays the remaining $200,000 (minus any deductible). Umbrella policies typically start at $1 million in coverage and cost $150 to $300 per year.
Umbrella coverage is not required, but it is worth considering if you own a home, have significant savings, or earn a high income. A lawsuit judgment can attach to your assets for years, so umbrella coverage protects what you have built. Your insurer will require you to carry a minimum car liability limit (usually 100/300/100) before they will sell you an umbrella policy.
Frequently Asked Questions
What happens if I cause an accident and do not have liability coverage?
You are breaking the law in every state except New Hampshire. You can be fined, your license can be suspended, and you can be sued personally for all damages. The injured party can pursue a judgment against your wages, bank accounts, and property. You should carry at least your state's minimum liability coverage at all times.
Does my liability coverage pay if someone sues me after an accident?
Yes. Your insurer will provide a lawyer to defend you in court, and they will pay any judgment or settlement up to your policy limit. If the judgment exceeds your limit, you are responsible for the difference. This is why many people carry more than the state minimum.
Can my insurer refuse to pay a liability claim?
Yes, if you were not at fault for the accident, if you intentionally caused the damage, or if you were committing a crime when the accident occurred. Your insurer can also deny a claim if you did not disclose material information when you bought the policy. If your claim is denied, you have the right to appeal or file a complaint with your state insurance commissioner.
If I am partially at fault, does my liability coverage still pay?
It depends on your state's fault rules. In "at-fault" states, your insurer pays only if you are found more than 50% responsible. In "no-fault" states, your own insurance pays your medical bills regardless of who caused the accident, and liability coverage only applies if damages exceed your no-fault coverage limits. Ask your insurer which rule applies in your state.
Should I buy more than the state minimum liability coverage?
Most insurance professionals recommend it. State minimums are often $15,000 to $25,000 per person, which is not enough to cover a serious injury or multiple vehicles. A $100,000 per-person limit costs only slightly more and protects your assets if you cause a major accident. If you own a home or have savings, umbrella coverage is also worth considering.
