Liability insurance covers damage you cause to someone else's car, property, or body
Liability insurance pays for injuries and property damage when you are found legally responsible for an accident. It does not cover damage to your own vehicle — that is what collision and comprehensive coverage do. Liability has two parts: bodily injury liability, which pays medical bills and lost wages for people you hurt, and property damage liability, which pays to repair or replace what you damaged.
The insurance company will defend you in court if someone sues, and will pay settlements or judgments up to your policy limits. If the damages exceed your limit, you are responsible for the rest. Most states require you to carry liability insurance before you can register a car, though the minimum amounts vary widely.
Key Takeaways
- Liability insurance pays for medical expenses, lost wages, and pain and suffering for people injured in an accident you caused.
- It also covers repair costs for other people's vehicles and property damage like fences, mailboxes, or storefronts.
- Your policy limit is the maximum the insurance company will pay; anything beyond that comes out of your pocket.
- Liability does not cover your own vehicle damage, rental car costs, or medical bills for you and your passengers — those require separate coverage.
Bodily injury liability: what medical costs it covers
Bodily injury liability pays medical expenses for anyone injured because of an accident you caused. This includes emergency room visits, surgery, hospital stays, physical therapy, and ongoing treatment. It also covers lost wages if someone cannot work during recovery, and pain and suffering damages awarded by a court.
The coverage applies to passengers in the other person's car, pedestrians, cyclists, and occupants of any vehicle involved. It does not cover you or your own passengers — they are covered under a different part of your policy called medical payments coverage or personal injury protection, depending on your state.
Bodily injury limits are written as two numbers, like 25/50, meaning $25,000 per person and $50,000 per accident. If three people are injured in one crash, the insurance company pays up to $25,000 to each person, but no more than $50,000 total. Once that total is reached, any additional claims come from your personal assets.
Property damage liability: vehicles, structures, and other belongings
Property damage liability covers the cost to repair or replace another person's vehicle, and also damage to fixed structures like fences, utility poles, storefronts, or parked cars. It pays for damage to personal property inside another vehicle, such as a phone or laptop, if that damage resulted from the accident.
Property damage limits are typically written as a single number, like 25 or 50, representing thousands of dollars. A $25,000 property damage limit means the insurance company will pay up to $25,000 for all property damage in one accident, regardless of how many vehicles or items are involved. If you cause $40,000 in damage with a $25,000 limit, you owe the remaining $15,000.
This coverage does not pay for damage to your own vehicle. It also does not cover damage to your own property, even if it was in your car at the time of the accident.
What liability insurance does not cover
Liability insurance does not pay for repairs to your own car, even if you caused the accident. Damage to your vehicle is covered under collision insurance (for crashes) or comprehensive insurance (for theft, weather, or vandalism). If you have only liability and cause an accident, your car stays damaged unless you pay out of pocket or file a claim under a different policy.
It also does not cover medical bills or lost wages for you and your passengers. Those are covered under medical payments coverage (available in all states) or personal injury protection (required in no-fault states). Liability is specifically for the other party's losses, not yours.
Liability does not cover rental car costs while your vehicle is being repaired, towing, roadside assistance, or uninsured motorist protection. These are separate add-ons you can purchase. It also does not cover intentional damage — if you deliberately hit someone or their property, the insurance company can deny the claim.
How liability limits work when damage exceeds your coverage
Your liability limit is a ceiling, not a may provide. If you cause an accident and the damages are greater than your policy limit, the insurance company pays only up to that limit. You are personally responsible for anything beyond it. This can mean wage garnishment, bank account levies, or a judgment against your home, depending on your state's laws.
For example, if your property damage limit is $25,000 and you cause $50,000 in damage to another car and a fence, the insurance company pays $25,000. The other party can sue you for the remaining $25,000. If they win, they can pursue collection through the court system.
This is why many insurance advisors recommend carrying higher limits than your state's minimum. Minimum liability limits in most states are $25,000 to $50,000 per person and $50,000 to $100,000 per accident, but a single serious injury can easily exceed those amounts. Raising your limit to $100,000 or $250,000 usually costs only a few dollars more per month.
Liability coverage when you are partially at fault
Liability insurance covers you even if you are partially responsible for an accident, but the amount the insurance company pays depends on your state's fault rules. In "at-fault" states, the person most responsible for the accident pays. In "no-fault" states, each person's own insurance pays their own losses regardless of who caused the accident.
In at-fault states, if you are found 30 percent at fault and the other person's damages are $10,000, your liability insurance pays $3,000 (30 percent of $10,000). The other person's insurance or their own coverage pays the rest. If you are found 100 percent at fault, your liability insurance covers the full amount up to your limit.
In no-fault states, the other person files a claim with their own insurance first, regardless of fault. Your liability insurance may still be involved if their damages exceed their coverage or if they sue you for pain and suffering above a certain threshold.
When liability insurance does not apply
Your liability insurance does not cover accidents that happen while you are using your car for commercial purposes, such as rideshare driving or food delivery, unless you have a commercial auto policy. Standard personal auto liability excludes business use.
It also does not cover accidents caused by someone else driving your car without permission, though the other person's own insurance may cover it. If you lend your car to a friend and they cause an accident, your liability insurance typically covers it, but the friend's insurance is considered secondary.
Liability does not apply to damage caused by mechanical failure, such as brake failure, unless you failed to maintain the vehicle and that negligence caused the accident. It also does not cover accidents that occur on private property where you have permission to be, though coverage usually applies on public roads and parking lots.
Frequently Asked Questions
Does liability insurance cover my medical bills if I am injured in an accident I caused?
No. Liability insurance covers the other person's medical bills, not yours. Your own medical expenses are covered under medical payments coverage or personal injury protection, which you can purchase as an add-on to your policy. These coverages pay regardless of who caused the accident.
What happens if I cause an accident and the damages are more than my liability limit?
The insurance company pays up to your limit, and you are responsible for the rest. The other party can sue you in court for the difference. If they win, they can pursue collection through wage garnishment, bank levies, or a judgment against your assets, depending on your state's laws.
Does liability insurance cover damage to my own car?
No. Liability covers damage you cause to other people's vehicles and property. Damage to your own car is covered under collision insurance (for crashes) or comprehensive insurance (for theft, weather, or vandalism). You must purchase these separately.
Will my liability insurance cover an accident if I was partially at fault?
Yes, but the amount depends on your state's rules. In at-fault states, your insurance pays a percentage based on your degree of fault. In no-fault states, each person's own insurance pays their losses first, regardless of who caused the accident.
Does liability insurance cover me if someone else is driving my car?
Yes, typically. Your liability insurance follows the car, so it covers accidents caused by someone driving your vehicle with your permission. The driver's own insurance is considered secondary. If the driver was using your car without permission, coverage may not apply.
