Liability coverage pays for injuries and property damage you accidentally cause to other people, up to your policy's limits, and it also pays for your legal defense if you're sued over a covered incident. It does not pay for your own injuries or your own property. Auto liability coverage is legally required in nearly every state, and liability protection is also a core part of homeowners and renters policies.
How it works
When you're at fault for an accident, the injured party (or their insurer) makes a claim against your liability coverage. Your insurance company investigates, negotiates, defends you in court if necessary, and pays covered damages up to your limits. Anything above your limits comes out of your own assets — which is why limits matter more than almost any other number on your policy.
Example: you rear-end another car and are clearly at fault. The other driver's medical bills come to $40,000 and their vehicle repairs to $10,000. If you carry liability limits of $100,000 per person for bodily injury and $50,000 for property damage, your insurer pays both amounts in full and you pay nothing beyond your premium. If you carried only a $25,000 bodily injury limit, you could be personally responsible for the remaining $15,000 of medical bills.
On auto policies, liability splits into two parts: bodily injury liability and property damage liability. On home policies, personal liability coverage works similarly for incidents like a guest injured on your property or damage your child or dog causes to others.
Why it matters for your policy
Liability limits are the worst place to economize. The premium difference between state-minimum limits and substantially higher limits is often modest, while the difference in protection is enormous — a single serious injury accident can exceed minimum limits many times over, exposing your savings, wages, and other assets.
A good rule of thumb: carry liability limits at least high enough to cover your net worth, and consider an umbrella policy once you have meaningful assets, since umbrella coverage adds another layer of liability protection above your auto and home limits at a relatively low cost. The most common mistake we see is drivers buying state-minimum limits to save a small amount per month without realizing what they've left exposed.

Frequently asked questions
Does liability coverage pay for my own car or injuries?
No. Liability coverage only pays other people for damage and injuries you cause. Your own vehicle is covered by collision and comprehensive coverage, and your own injuries by medical payments coverage, personal injury protection, or your health insurance, depending on your policy and state.
How much liability coverage do I need?
More than the state minimum in almost every case. A common starting point is 100/300/100 — $100,000 per person and $300,000 per accident for bodily injury, plus $100,000 for property damage — and higher if you have significant assets or income to protect. An umbrella policy is worth considering once your net worth exceeds your underlying limits.
Is liability coverage required by law?
For auto insurance, nearly every state requires minimum liability limits to register and drive a car, though the required amounts vary by state. Homeowners liability coverage isn't required by law, but mortgage lenders require a homeowners policy, and liability protection comes standard within it.
