Liability insurance is the foundation of every auto insurance policy in the United States. It’s the type of coverage that virtually every state requires, and for good reason. When you cause an accident, liability insurance pays for the other person’s injuries and property damage.
Understanding how liability insurance works can save you from financial disaster. Without adequate coverage, a single accident could leave you personally responsible for hundreds of thousands of dollars in damages.
What Is Liability Insurance?
Liability insurance protects you financially when you’re at fault in an accident. It covers two main areas: bodily injury liability and property damage liability. These are often listed together in a format like 25/50/25, which represents the coverage limits in thousands of dollars.
Bodily injury liability pays for medical expenses, lost wages, pain and suffering, and legal fees for people you injure in an accident. Property damage liability covers the cost of repairing or replacing the other driver’s vehicle and any other property you damage, such as fences, buildings, or utility poles.
How Liability Limits Work
Liability limits are expressed as three numbers. Using the example of 100/300/100, here’s what each number means. The first number (100) is the maximum amount your insurer will pay per person for bodily injury — in this case, $100,000. The second number (300) is the maximum total your insurer will pay for all bodily injuries in a single accident — $300,000. The third number (100) is the maximum for property damage — $100,000.
If the costs of an accident exceed your liability limits, you’re personally responsible for the remaining amount. This is why many financial advisors recommend carrying higher limits than the state minimum, especially if you have significant assets to protect.
State Minimum Requirements
Every state except New Hampshire requires drivers to carry minimum liability insurance. However, state minimums are often dangerously low. For example, some states require as little as 15/30/5, which means only $5,000 in property damage coverage — barely enough to cover a fender bender with a newer vehicle.
Financial experts generally recommend carrying at least 100/300/100 in liability coverage. If you have substantial assets like a home or savings, you may want even higher limits or an umbrella policy for additional protection.
What Liability Insurance Does NOT Cover
It’s important to understand that liability insurance only pays for other people’s losses — not yours. It won’t cover your own medical bills if you’re injured in an accident you caused. It won’t pay to repair your own vehicle. And it doesn’t cover intentional acts or damage caused while committing a crime.
For protection of your own vehicle and medical expenses, you’ll need additional coverage types such as collision, comprehensive, and medical payments or personal injury protection.
How Much Does Liability Insurance Cost?
Liability insurance is typically the least expensive part of your auto insurance policy. The exact cost depends on factors like your driving record, age, location, and the coverage limits you choose. Higher limits cost more, but the increase is usually modest compared to the additional protection you receive.
For example, doubling your liability limits from 50/100/50 to 100/300/100 might only add $50 to $100 per year to your premium — a small price to pay for significantly better financial protection.
