Liability coverage: what it is and what it does

What it generally means

Liability coverage helps pay for injuries and property damage you are found legally responsible for causing to other people in a covered accident, up to the limits in your policy.

Auto liability is commonly described with three limits, such as 25/50/20 in a hypothetical example: the most the policy would pay for one person's injuries, for everyone's injuries in one accident, and for property damage in one accident. The policy document — not any website — is the authority on how your own policy works.

What it generally covers

• Medical costs and related losses of people injured when you are found legally responsible for a covered accident, up to your bodily-injury limits
• Repair or replacement costs for other people's property — such as their vehicle, fence, or mailbox — up to your property-damage limit
• In many policies, legal defense costs if you are sued over a covered accident (the policy controls the details)

What it generally does not cover

• Injuries to you or damage to your own vehicle from the accident
• Costs above the limits you selected — you may be responsible for the difference
• Damage or injuries excluded by the policy, or losses caused by drivers or vehicle uses the policy does not cover

Every policy is different. Exclusions, limits, and definitions live in the policy itself, so treat any summary — including this one — as a starting point, not as your policy.

A simple example

Example only — not a rate, a recommendation, or an estimate of any real claim: Imagine you are found at fault in an intersection crash. The other driver's car needs repairs and they have medical bills. Your liability coverage would be the part of your policy that helps pay the other driver's repair costs and medical costs, up to the limits you chose. Your own car repairs would be a separate question, addressed by other coverages such as collision.

How state rules fit in

State minimums vary. See our Illinois requirements guide for how one state handles required liability and uninsured-motorist minimums.

Questions to ask an insurer or licensed agent

Bring these to any quote or policy conversation:

• What are my liability limits — per person, per accident, and for property damage — and what does each mean?
• What happens if a claim exceeds my limits, and how much of the difference would I owe?
• Which household members and permitted drivers does my policy cover?
• What situations or vehicle uses does my policy exclude?
• How do my state's required minimums compare with the limits I carry now?

• Uninsured / underinsured motorist: Can help when an at-fault driver has no insurance — or not enough of it.
