Liability coverage pays for damage or injury you cause to someone else in a car accident — not damage to your own car.
When you hit another vehicle, injure a pedestrian, or damage property with your car, liability coverage is what pays their medical bills, vehicle repairs, or legal costs if they sue. It does not cover your own injuries or your own car's damage. Most states require you to carry it by law, and your lender will require it if you have a loan or lease.
Liability coverage has two parts: bodily injury liability covers medical expenses and lost wages for people you hurt, and property damage liability covers repairs to vehicles, buildings, or other property. Your policy shows these as two separate limits — for example, 25/50/25 means $25,000 per person for injuries, $50,000 total per accident for injuries, and $25,000 for property damage.
Key Takeaways
- Liability coverage pays for injuries and property damage you cause to others, not damage to your own vehicle or medical bills for your own injuries.
- 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 damage you cause exceeds your liability limit, you can be sued personally for the difference, which may result in wage garnishment or asset seizure.
- Umbrella insurance adds extra liability protection beyond your car policy's limits and costs far less than raising your car insurance limits alone.
How liability coverage works after an accident
After you cause an accident, your insurance company investigates the claim. If you are found at fault, your insurer pays the other person's medical bills, vehicle repairs, and other damages up to your policy limits. They also handle the legal defense if the other person sues you.
The other person's insurance company may also file a claim against your policy — this is called a subrogation claim. Your insurer will negotiate with them to determine fault and settle the amount owed. You do not have to pay anything out of pocket as long as the total damage stays within your liability limits.
State minimum liability limits and why they matter
Every state sets a minimum liability limit you must carry. These minimums vary widely: 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), while others require 25/50/25 or higher. Your state's Department of Motor Vehicles or your insurer can tell you your state's exact requirement.
The problem is that state minimums are often far too low. A serious accident with multiple injuries or significant property damage can easily exceed these limits. If you cause $100,000 in damage but your property damage limit is only $25,000, you are personally responsible for the remaining $75,000. The injured person can sue you directly, and a court judgment can result in wage garnishment, bank account levies, or a lien on your home.
The difference between liability and collision or comprehensive coverage
Liability covers damage you cause to others. Collision coverage covers damage to your own car when you hit another vehicle or object, regardless of fault. Comprehensive coverage covers damage from theft, weather, vandalism, or hitting an animal — again, to your own car only.
If you cause an accident, your liability coverage pays for the other person's car. Your collision coverage (if you have it) pays for your own car's repairs. You can have liability without collision or comprehensive, but most lenders require all three if you are financing or leasing a vehicle.
What liability coverage does not cover
Liability does not cover your own medical bills or lost wages — that is what medical payments coverage or personal injury protection is for. It also does not cover damage to your own vehicle, theft of your car, or damage from weather or animals.
Liability also does not cover intentional damage, criminal acts, or accidents that happen while you are using your car for commercial purposes (like food delivery or rideshare) unless you have a commercial auto policy. If you use your personal car for business regularly, tell your insurer — they may require you to upgrade your policy or switch to a commercial plan.
How to choose the right liability limits for your situation
Start by checking your state's minimum requirement, but do not stop there. Consider your assets — your home, savings, investments, and future income. If you cause a serious accident and the judgment exceeds your liability limit, a court can garnish your wages or place a lien on your home for years.
A common rule is to carry liability limits equal to your net worth, or at least $100,000 per person and $300,000 per accident if your net worth is higher. If you have significant assets, umbrella insurance is the most cost-effective way to add protection. An umbrella policy adds $1 million or more in liability coverage for $150 to $300 per year, whereas raising your car insurance limits alone costs much more.
What happens if you cause an accident without enough liability coverage
If the damage you cause exceeds your liability limit, the injured person can sue you personally. They will likely win a judgment against you, and then they can pursue collection through wage garnishment, bank levies, or a lien on your home. This process can take years and significantly damage your credit.
Some states allow you to keep a portion of your home or wages safe from collection, but these protections vary. The safest approach is to carry enough liability coverage upfront so that a serious accident does not wipe out your assets. If you cannot afford higher limits on your car policy, umbrella insurance fills the gap cheaply.
Frequently Asked Questions
Does liability coverage pay for my own injuries if I cause an accident?
No. Liability covers injuries to other people, not you. Your own medical bills are covered by medical payments coverage or personal injury protection, which you purchase separately. If you do not have either, your health insurance or your own savings must cover your treatment.
What if the other person was partially at fault for the accident?
That depends on your state's fault rules. In "at-fault" states, the person most responsible pays. In "comparative fault" states, damages are split based on each person's percentage of fault. Your insurer handles this negotiation with the other person's insurer. You do not need to decide fault yourself.
Can I be sued if my liability coverage pays the full claim?
The other person can still sue you, but your insurer will defend you in court. Once your insurer pays out your policy limit, you become personally responsible for any additional damages. This is why carrying adequate limits matters — it protects your personal assets.
Does liability coverage apply if someone else drives my car?
Yes, as long as they have your permission. Your liability coverage follows the car, not the driver. If a friend borrows your car and causes an accident, your liability coverage pays for the damage they cause. Make sure anyone who regularly drives your car knows this and drives carefully.
What is the difference between per-person and per-accident liability limits?
Per-person limits cap what your insurer pays to any single injured person. Per-accident limits cap the total payout for all injured people in one accident. If you have 25/50 bodily injury limits and injure three people, your insurer pays up to $25,000 to each person, but no more than $50,000 total across all three.
