Liability insurance pays for damage or injury you cause to someone else with your car
Liability insurance covers the cost of injuries and property damage you're legally responsible for after an accident. If you hit another car, a pedestrian, or someone's fence, your liability coverage pays their medical bills, vehicle repairs, or other losses — up to your policy limit. It does not cover damage to your own vehicle or injuries to you.
Every state except New Hampshire requires you to carry liability insurance before you can legally drive. The minimum amounts vary by state, but most require at least $25,000 per person for injuries and $50,000 per accident. These minimums are often too low to cover serious accidents, which is why many insurers and financial advisors recommend higher limits.
Liability insurance has two parts: bodily injury liability, which covers medical expenses and lost wages for people you injure, and property damage liability, which covers repairs or replacement of vehicles, buildings, or other property. Your policy shows these as separate numbers — for example, 50/100/50 means $50,000 per person for injuries, $100,000 total per accident for injuries, and $50,000 for property damage.
Key Takeaways
- Liability insurance is required in every state except New Hampshire and covers injuries and property damage you cause to others, not damage to your own vehicle.
- Your policy limits determine the maximum the insurance company will pay, and state minimums are often lower than the actual cost of serious accidents.
- Bodily injury liability covers medical bills and lost wages for injured people, while property damage liability covers vehicle and building repairs.
- If you cause an accident and your liability limit is too low, you can be sued for the difference and may face wage garnishment or asset seizure.
How liability insurance works after an accident
When you cause an accident, the other person can file a claim with your insurance company. Your insurer investigates the accident, determines whether you're legally responsible, and if so, pays the injured party up to your policy limit. You do not pay the claim yourself — the insurance company handles it directly.
If the damages exceed your policy limit, you become personally responsible for the rest. For example, if you cause a $150,000 accident but your liability limit is $50,000, your insurance pays $50,000 and you owe the remaining $100,000. The injured party can sue you in court to recover that amount, and if they win, they can garnish your wages or place a lien on your home or other assets.
Your insurance company also provides a lawyer to defend you if you're sued, as long as the claim falls within your policy coverage. This legal defense is included in your liability coverage at no extra cost.
State minimum liability limits versus recommended coverage
State minimums exist to ensure every driver can pay for at least some damage they cause, but they often fall short of real-world accident costs. A serious injury accident involving hospitalization, surgery, or permanent disability can easily exceed $100,000. A multi-car highway pileup can reach $500,000 or more.
Most insurance agents recommend carrying limits of at least $100,000 per person and $300,000 per accident for bodily injury, plus $100,000 for property damage. These higher limits cost only $10 to $30 more per month than state minimums but protect you from a lawsuit that could take years to resolve and damage your financial future.
If you have significant assets — a home, savings, investments, or a steady income — higher liability limits are especially important. A court judgment against you can follow you for years, and creditors can pursue collection even after your insurance limit is exhausted.
What liability insurance does not cover
Liability insurance does not pay for damage to your own vehicle, medical bills for you or your passengers, or lost wages if you're injured. Those losses are covered by separate types of insurance: collision coverage pays for your vehicle damage regardless of fault, and medical payments coverage (or personal injury protection in some states) covers medical expenses for you and your passengers.
Liability also does not cover intentional damage, accidents while committing a crime, or damage caused while using your car for commercial purposes like rideshare or delivery without a commercial policy. If you use your car for work, tell your insurer — they may require a commercial or rideshare endorsement.
Accidents caused by mechanical failure, weather, or an animal in the road are still your responsibility to report, but they're usually covered under comprehensive coverage rather than liability. Liability only applies when you're found legally at fault.
How liability limits are written on your policy
Insurance companies use a three-number format to show your liability limits. A policy labeled 25/50/25 means $25,000 per person for bodily injury, $50,000 total per accident for bodily injury, and $25,000 for property damage. The first two numbers are bodily injury limits; the third is property damage.
When you buy a policy, you choose these limits. Higher limits cost more, but the difference is usually modest. Jumping from the state minimum (often 25/50/25) to a more protective level (100/300/100) typically adds $15 to $40 per month depending on your age, driving record, and location.
Some insurers offer umbrella or excess liability policies that sit on top of your auto liability coverage. These kick in only after your auto liability limit is exhausted and can cover $1 million or more in additional protection for $100 to $300 per year. They're worth considering if you own a home or have other assets to protect.
Liability insurance and uninsured or underinsured drivers
If another driver causes an accident but has no insurance or insufficient liability limits, your own liability coverage does not help you — it only covers damage you cause to others. Instead, you'd rely on uninsured motorist coverage or underinsured motorist coverage, which are separate add-ons that protect you when the other driver cannot pay.
Many states require insurers to offer these coverages, though you can decline them in writing. If you live in a state with a high rate of uninsured drivers, carrying uninsured motorist coverage is a practical way to protect yourself without relying on the other driver's insurance.
Frequently Asked Questions
What happens if I cause an accident and don't have liability insurance?
You face criminal penalties including fines, license suspension, and possible jail time depending on your state and whether anyone was injured. You're also personally liable for all damages, meaning the injured party can sue you and garnish your wages or seize assets. Many states require you to carry proof of insurance or file an SR-22 form for several years after an uninsured accident.
Can I get liability insurance with a bad driving record?
Yes, but you'll pay higher premiums. Accidents, speeding tickets, and DUIs increase your rate because insurers view you as higher risk. Some insurers specialize in high-risk drivers, though their rates are significantly more expensive. Your rate usually improves after three to five years without new violations.
Does my liability insurance cover rental cars?
Usually yes, but check your policy. Most auto insurance covers you when you're driving a rental car, though the rental company may require you to decline their collision damage waiver. Some policies exclude rentals or limit coverage, so call your insurer before renting to confirm you're covered.
What's the difference between liability and collision coverage?
Liability covers damage you cause to others; collision covers damage to your own vehicle regardless of fault. Liability is required by law; collision is optional but recommended if you have a loan or lease. You can have liability without collision, but not the reverse.
Will my liability insurance go up after an accident?
Usually yes, especially if you're found at fault. Most insurers increase rates by 20 to 40 percent after an at-fault accident, though the increase varies by company and your driving history. The rate increase typically lasts three to five years. Shopping around after an accident can sometimes find a company that rates you lower.
