What Is Liability Insurance for Your Car?

Liability insurance pays for injuries and property damage you cause to others in an at-fault accident. It's legally required in nearly every state, and it covers the other driver's bills—not your own vehicle or medical expenses.

What Is Liability Insurance Insurance?

Liability insurance consists of two components: bodily injury liability and property damage liability. Bodily injury liability pays for the other party's medical bills, lost wages, pain and suffering, and legal fees if you're sued after an at-fault accident. Property damage liability covers repairs or replacement of the other driver's vehicle, plus any other property you damage—fences, mailboxes, storefronts, or guardrails. Your insurer will defend you in court and pay settlements or judgments up to your policy limits.

How Much Does Liability Insurance Insurance Cost?

  • Coverage limits directly affect cost—increasing from 25/50/25 to 100/300/100 can add $200 to $400 per year to your premium.
  • At-fault accidents and traffic violations in the past three to five years can increase liability premiums by 20% to 50% or more.
  • Your state's minimum requirements set the baseline cost—states with higher mandated limits have higher average premiums.
  • Urban drivers pay more than rural drivers due to higher accident frequency and costlier claims in densely populated areas.
  • Credit-based insurance scores influence rates in most states, with lower scores correlating to higher liability premiums.
  • Annual mileage affects risk exposure—drivers logging over 15,000 miles per year typically face higher liability costs than those driving under 7,500 miles.
