Liability coverage pays for damage or injuries you cause to someone else in an accident
Liability insurance is the part of your car insurance that covers the other person's medical bills, vehicle repairs, or property damage if you're found at fault in an accident. It does not cover your own injuries or your own car. Most states require you to carry it by law, and your lender will require it if you have a loan or lease on your vehicle.
When you cause an accident, liability coverage steps in to pay the other driver's hospital bills, lost wages, pain and suffering claims, and the cost to fix or replace their vehicle. It also covers legal defense if they sue you. Without it, you would be personally responsible for those costs, which can easily exceed $100,000 in a serious accident.
Liability has two parts: bodily injury liability covers injuries to people, and property damage liability covers damage to vehicles and 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 insurance pays for injuries and property damage you cause to others, not damage to your own vehicle or injuries to yourself.
- Most states legally require you to carry liability insurance, and lenders require it on financed or leased vehicles.
- Your policy shows two limits: bodily injury liability (per person and per accident) and property damage liability (per accident).
- The minimum required coverage varies by state but is often too low to protect your personal assets if a serious accident occurs.
- Liability does not cover medical payments to you, uninsured drivers, or collision damage to your own car — those require separate coverage.
How liability limits work and why the minimum may not be enough
Every state sets a minimum liability limit you must carry. These minimums are usually low — often $25,000 per person for bodily injury and $50,000 total per accident. A single serious injury can cost far more than that. Hospital stays, surgery, ongoing physical therapy, and lost wages can easily reach $100,000 or $200,000. If the injured person sues you and wins a judgment larger than your policy limit, you could be responsible for the difference.
Many insurance companies and financial advisors recommend carrying limits higher than your state's minimum — often $100,000 per person and $300,000 per accident for bodily injury, with $100,000 for property damage. The cost difference between minimum and higher limits is usually small, often $10 to $30 per month. If you have significant assets (a house, savings, investments), higher limits protect those assets from being seized to pay a judgment.
You can also add umbrella insurance, which sits on top of your car insurance and covers claims that exceed your liability limits. A $1 million umbrella policy typically costs $150 to $300 per year and covers not just car accidents but also injuries that happen on your property.
What liability does not cover
Liability insurance does not pay for your own medical bills or vehicle damage. If you're injured in an accident you caused, your own health insurance or medical payments coverage (a separate add-on) would cover your treatment. If your car is damaged, collision coverage or comprehensive coverage would pay for repairs, depending on what caused the damage.
Liability also does not cover damage caused by an uninsured or underinsured driver. If someone without insurance hits you, uninsured motorist coverage steps in to cover your injuries and vehicle damage. These are separate coverages you add to your policy.
If you cause an accident while driving someone else's car with their permission, their liability insurance typically covers it, not yours. If you cause an accident while driving for work (like food delivery or rideshare), your personal auto policy may not cover it — you may need commercial or rideshare coverage instead.
How a liability claim actually works
After an accident, the other driver (or their insurance company) files a claim with your insurer. Your insurance company investigates — they'll look at the police report, photos, witness statements, and medical records. If they determine you're at fault, they'll offer to settle the claim or defend you in court if the other party sues.
Your insurer pays the settlement or judgment directly to the other party, up to your policy limits. You don't write the check yourself. However, if the judgment exceeds your limits, you are personally responsible for the overage. This is why higher limits matter: they protect your wages and assets from being garnished or seized.
The claims process usually takes weeks to months, depending on the severity of injuries and whether the other party is willing to settle. Your insurer will assign you a claims adjuster who handles communication with the other party and their medical providers.
Liability and fault: what determines who pays
Liability coverage only pays if you're found at fault for the accident. Fault is determined by the police report, witness statements, traffic laws, and sometimes expert reconstruction of the accident. In some states, you can be found partially at fault — for example, 70% at fault and 30% at fault. In those states, your liability coverage pays only your percentage of the damages.
If you're found not at fault, your liability insurance doesn't pay anything. The other driver's liability insurance would cover your damages instead. This is why it's important to report accidents to police and document everything — the police report and evidence help establish who was at fault.
If liability is unclear or disputed, your insurance company may still defend you in court even if they eventually have to pay a settlement. That's part of what your liability premium covers.
State minimum liability requirements vary widely
Every state requires liability insurance, but the minimum amounts differ. Some states require as little as $15,000 per person for bodily injury. Others require $50,000 or more. A few states allow you to self-insure (prove you have enough money to cover claims) instead of buying a policy, but this is rare and usually only available to large businesses or wealthy individuals.
If you move to a different state or travel across state lines, your policy follows you and meets that state's minimum requirements. However, if you're caught driving without insurance, you face fines, license suspension, and potentially jail time, depending on the state.
You can check your state's specific minimums through your state's Department of Insurance or your insurance agent. Your policy documents will also show what your state requires and what you're currently carrying.
Frequently Asked Questions
Does liability insurance cover damage to my own car?
No. Liability only 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, vandalism). These are separate add-ons you purchase.
What happens if I cause an accident and don't have enough liability coverage?
If the judgment exceeds your policy limits, you're personally responsible for the difference. The other party can sue you directly, garnish your wages, or place a lien on your home or other assets. This is why carrying limits higher than your state's minimum is important if you have assets to protect.
Does my liability insurance cover me if I'm driving someone else's car?
Usually, yes — your policy typically covers you when you drive with the owner's permission. However, if you regularly drive someone else's car, they should add you as a named driver to their policy. If you're driving for work (delivery, rideshare), your personal policy may not cover it, and you'll need commercial or rideshare coverage instead.
Can I be sued even if my insurance pays the claim?
Yes. If the judgment exceeds your policy limits, the other party can sue you personally for the overage. Your insurance company will defend you in court, but they're only obligated to pay up to your policy limits. Umbrella insurance protects you from personal liability beyond those limits.
What's the difference between bodily injury and property damage liability?
Bodily injury liability covers medical bills, lost wages, and pain and suffering for people injured in an accident you cause. Property damage liability covers repairs or replacement of vehicles and other property. Your policy shows separate limits for each because injuries are usually more expensive than vehicle damage.
