What Liability Insurance Covers When You Cause a Car Accident

Liability insurance pays for damage or injury you cause to someone else

Liability insurance covers the cost of injuries and property damage you cause to another person when you're at fault in a car accident. It does not cover damage to your own vehicle, your own medical bills, or injuries to your passengers — those are handled by other types of coverage. Liability is the most basic form of car insurance and is required by law in every state.

When you cause an accident, your liability insurance pays the other driver's medical expenses, lost wages, pain and suffering, and the cost to repair or replace their vehicle. It also covers their legal fees if they sue you. The insurance company handles the claim and the settlement, so you don't pay out of pocket.

Each state sets a minimum amount of liability coverage you must carry. These minimums are written as three numbers — for example, 25/50/25 — which represent the dollar limits for bodily injury per person, bodily injury per accident, and property damage per accident. A state minimum of 25/50/25 means the insurer 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.

Key Takeaways

• Liability insurance covers injuries and property damage you cause to others, but not damage to your own car or your own medical bills.
• Every state requires a minimum amount of liability coverage, and the minimum varies by state — check your state's requirement before buying a policy.
• Your insurer pays the other driver's medical bills, vehicle repairs, and legal costs if they sue, up to your policy limit.
• If the damage or injuries exceed your policy limit, you may be responsible for the remaining amount out of your own pocket.

Bodily injury liability covers medical costs and lost income

Bodily injury liability is the part of your liability coverage that pays for injuries to other people. It covers hospital bills, surgery, physical therapy, prescription medications, and ongoing treatment. It also covers lost wages if the injury prevents them from working, and pain and suffering damages if they pursue a lawsuit.

The first number in your coverage limit applies to each person injured. If your policy is 25/50/25 and you injure two people, the insurer will pay up to $25,000 for each person's injuries — $50,000 total. If one person's injuries cost $35,000, your policy pays $25,000 and you are responsible for the remaining $10,000.

Bodily injury liability also covers death. If someone dies from injuries you caused, the insurer pays funeral expenses and any wrongful death claims the family files, up to your per-person limit.

Property damage liability covers vehicle repairs and other damage

Property damage liability covers the cost to repair or replace the other driver's vehicle, as well as damage to their property. This includes their car, fence, mailbox, storefront, or any other structure or object you damage in the accident.

The limit for property damage is a single number — the third number in your coverage ratio. A policy of 25/50/25 has a $25,000 property damage limit. If you hit a parked car and cause $18,000 in damage, your insurer pays the full amount. If you cause $30,000 in damage, your insurer pays $25,000 and you owe the remaining $5,000.

Property damage liability does not cover damage to your own vehicle. If you cause an accident and your car is damaged, you need collision coverage to pay for repairs to your own car.

State minimum coverage limits vary widely

Every state requires liability insurance, but the minimum amount differs. Some states set minimums as low as 15/30/5 (Alabama, Kentucky, Mississippi), while others require 50/100/25 (Connecticut, Delaware, Maine) or higher. A few states allow drivers to meet the requirement through other means, such as a bond or proof of financial responsibility, but liability insurance is the standard method.

The state minimum is the least amount you can legally carry. Many drivers choose higher limits because the state minimum may not cover the full cost of a serious accident. If you cause injuries that cost $75,000 and your policy limit is 50/100/25, your insurer pays $50,000 and you are liable for the remaining $25,000. The other driver can sue you personally to recover that amount, and a court can garnish your wages or place a lien on your home.

You can find your state's minimum liability requirements through your state's insurance commissioner or department of motor vehicles website.

What happens when you exceed your policy limit

If the cost of injuries or property damage exceeds your policy limit, you are personally responsible for the difference. The other driver can sue you in civil court to recover the amount your insurance did not pay. If they win the lawsuit, the court can order you to pay through wage garnishment, bank account levies, or a lien on your home or other property.

This is why many insurance experts recommend carrying limits higher than your state's minimum. A policy of 100/300/100 costs more than the state minimum but provides more protection if you cause a serious accident. The additional cost is usually modest — often $10 to $30 per month — compared to the risk of a lawsuit that could affect your finances for years.

Some policies include umbrella coverage, which provides additional liability protection above your car insurance limits. Umbrella policies typically start at $1 million in coverage and cost $150 to $300 per year. They cover liability claims that exceed your car insurance limits, protecting your personal assets.

Liability does not cover your own injuries or vehicle damage

Liability insurance is designed to protect the other person, not you. It does not pay for your own medical bills, lost wages, or pain and suffering, even if you are injured in the accident you caused. It also does not cover damage to your own vehicle.

To cover your own injuries, you need medical payments coverage (also called med pay) or personal injury protection (PIP), depending on your state. These coverages pay your hospital bills and lost wages regardless of who caused the accident. To cover damage to your own car, you need collision coverage (for accidents) or comprehensive coverage (for theft, weather, or vandalism).

If you are hit by an uninsured or underinsured driver, uninsured/underinsured motorist coverage pays for your injuries and vehicle damage when the other driver's insurance is insufficient or nonexistent.

How liability claims are handled

When you cause an accident, you report it to your insurance company. The insurer assigns a claims adjuster who investigates the accident, reviews police reports, interviews witnesses, and obtains repair estimates. The adjuster determines fault and the cost of damages, then negotiates a settlement with the other driver or their insurer.

If the other driver sues you, your insurance company provides a lawyer to defend you at no cost to you. The insurer pays any settlement or judgment up to your policy limit. You do not have to appear in court unless the case goes to trial, and you do not pay legal fees out of pocket.

If the settlement or judgment exceeds your policy limit, your insurer pays only up to the limit. You are responsible for any amount above that. This is why understanding your coverage limits and choosing appropriate limits for your situation matters.

Frequently Asked Questions

Does liability insurance cover damage to my own car?

No. Liability insurance covers damage you cause to someone else's vehicle or property. To cover damage to your own car, you need collision coverage (for accidents) or comprehensive coverage (for theft, weather, or other non-collision damage). These are separate coverages you purchase in addition to liability.

What if I cause an accident but the other driver was partially at fault?

This depends on your state's fault rules. In "at-fault" states, the driver who caused the accident pays. In "no-fault" states, each driver's own insurance pays for their injuries regardless of who caused the accident. Your insurer will investigate and determine fault based on police reports, witness statements, and evidence from the scene.

Can I be sued personally if my liability limit is too low?

Yes. If damages exceed your policy limit, the other driver can sue you personally to recover the remaining amount. A court can order wage garnishment, bank levies, or a lien on your property. This is why many people carry limits higher than their state's minimum.

Does my liability insurance cover my passengers if they're injured?

No. Your liability insurance covers injuries you cause to people in other vehicles or pedestrians. Injuries to your own passengers are covered by medical payments coverage (med pay) or personal injury protection (PIP), which you purchase separately.

What's the difference between liability and umbrella insurance?

Liability insurance is your primary coverage and pays up to your policy limit. Umbrella insurance provides additional coverage above your liability limit — typically starting at $1 million — and costs $150 to $300 per year. It protects your personal assets if a lawsuit exceeds your car insurance limits.
