What Is Liability Insurance Insurance?
Liability insurance has two parts: bodily injury liability and property damage liability. Bodily injury liability pays for medical bills, lost wages, and legal costs if you injure someone in an accident you caused. Property damage liability covers repairs to another person's car, fence, mailbox, or other property you damage. Both parts include legal defense costs if you're sued.
Who Needs Liability Insurance Insurance?
Liability insurance is required by law in 48 states, so nearly everyone needs it to legally register and drive a car. Even in New Hampshire and Virginia where it's technically optional, you're personally liable for any damage you cause — one serious accident could cost you tens of thousands or more.
If you're legally required to have it, buy it — but don't stop at state minimums unless that's truly all you can afford. A good rule: choose bodily injury limits at least equal to your net worth or future earning potential, because you can be sued for the difference if you cause a serious accident.
How Much Does Liability Insurance Insurance Cost?
- Your coverage limits — choosing 100/300/100 instead of state minimums can double your premium, but minimums often leave you financially exposed.
- Where you live — urban areas with more traffic and higher accident rates cost more, and some states like Michigan or Louisiana have premiums double the national average.
- The type of car you drive — higher-value or high-performance vehicles can increase liability costs because damage you cause may be more expensive.
Frequently Asked Questions
Does liability insurance cover me if I borrow someone else's car?
Liability insurance generally follows the car, not the driver. If you borrow a friend's car and cause an accident, their liability insurance pays first — but if the damages exceed their limits, your own liability policy may kick in as secondary coverage. Always confirm the car owner has adequate insurance before driving, because you could still be held personally liable for costs beyond their policy limits.
Can I get liability-only insurance if I have a car loan?
No — lenders require collision and comprehensive coverage to protect their financial interest in the vehicle until the loan is paid off. Liability-only policies are typically only an option if you own your car outright. Once you've paid off the loan, you can drop collision and comprehensive if your car's value is low, but you must always keep liability coverage to drive legally in most states.
