Liability, Collision and Comprehensive: The Three Core Coverages

Three different jobs

Auto insurance policies are usually assembled from several coverage types, but three form the core of most policies. They're easy to blur together, but each protects against something different.

Liability coverage

Liability covers costs you're responsible for when you cause an accident that injures someone else or damages their property. It typically splits into:

• Bodily injury liability — medical costs, lost wages and related expenses for people you injure
• Property damage liability — repair costs for another person's vehicle or property

Liability does not pay for your own vehicle's damage or your own injuries — it protects the other party, and it's the coverage most states require by law at some minimum level.

Collision coverage

Collision pays to repair or replace your own vehicle after a collision with another vehicle or object, regardless of who caused it — a fence, a guardrail, or another car. It's optional in most states, but often required by a lender or lessor while a loan or lease is active.

Comprehensive coverage

Comprehensive covers damage to your own vehicle from causes other than a collision — theft, vandalism, fire, weather events, falling objects, or hitting an animal. Like collision, it's typically optional unless a lender requires it.

Other coverages you'll see

Policies often include more than these three. Uninsured/underinsured motorist coverage protects you when the at-fault driver has no insurance or too little of it, and personal injury protection (PIP) or medical payments coverage helps with your own and your passengers' medical costs regardless of fault. Some states require one or more of these, so what's mandatory depends on where you live.

How they fit together

A common setup is liability (often required) plus collision and comprehensive (often required while financed or leased, optional once a vehicle is paid off). Whether to keep collision and comprehensive on an older, lower-value vehicle once it's paid off is a personal call, often weighed against the vehicle's current value and what the coverage costs.
