What is liability insurance?
By Colson · Updated June 13, 2026
Liability insurance covers the cost of injuries or property damage you're legally responsible for — it pays others, not you. It's the core of auto and home policies and the part that protects your savings from a lawsuit after an accident.

In auto insurance, liability pays for the other driver's injuries and vehicle/property damage when you cause a crash, plus your legal defense. In home insurance, personal liability covers injuries to guests on your property or damage you cause to others. It does not cover your own injuries or property — that's what other coverages are for.
Understanding the limit numbers
Auto liability is written as three numbers like 100/300/100: $100,000 bodily injury per person, $300,000 per accident, and $100,000 property damage. State minimums are often much lower (e.g., 25/50/25), which can leave you personally liable for the rest after a serious crash.
How much liability you should carry
Carry enough to protect your net worth — a common recommendation is 100/300/100 for auto and at least $300,000 of home liability, with an umbrella policy on top if you have significant assets. Under-insuring liability to save a little is the riskiest place to cut.
Frequently asked questions
What does liability insurance not cover?
Your own injuries or property. Auto liability won't repair your car (that's collision/comprehensive), and home liability won't fix your house (that's dwelling coverage). It only pays for harm you cause to others.
What does 100/300/100 mean?
$100,000 bodily-injury coverage per person, $300,000 per accident, and $100,000 for property damage — a widely recommended auto liability level that protects your assets better than state minimums.
Is liability insurance required?
Auto liability is required in almost every state. Home liability isn't legally required but is included in standard homeowners and renters policies and strongly recommended.
