Auto insurance policies are bundles of several different coverages, each protecting you against a different kind of loss. Understanding what each one does makes it much easier to choose the right policy and avoid paying for protection you do not need — or skipping something you do. Here is a plain-English breakdown of the main coverage types.
Liability coverage (required almost everywhere)
Liability is the foundation of every policy and is required in nearly every state. It pays for damage and injuries you cause to other people — it does not cover your own car or injuries. It comes in two parts:
- Bodily injury liability — covers other people’s medical costs when you are at fault
- Property damage liability — covers damage you cause to other vehicles or property
Liability limits are often written as three numbers (for example, 100/300/100), representing thousands of dollars of coverage per person injured, per accident, and for property damage. Carrying only your state’s minimum limits is risky; a serious accident can easily exceed low limits and leave you paying the rest yourself.
Collision coverage
Collision pays to repair or replace your own car after an accident, regardless of who is at fault — whether you hit another vehicle, an object, or roll your car. If you have a loan or lease, your lender almost always requires it. If you own an older, low-value car outright, it may not be worth the cost.
Comprehensive coverage
Comprehensive covers damage to your car from things other than a collision. Think of it as protection against the world:
- Theft and vandalism
- Fire, hail, floods, and other weather events
- Falling objects and hitting an animal
- Broken glass and windshield damage
Collision and comprehensive together are what people usually mean by “full coverage.” Both are subject to a deductible you choose.
Uninsured and underinsured motorist coverage
This protects you when the other driver is at fault but has no insurance, or not enough to cover your costs. Given how many drivers on the road are underinsured, it is valuable protection and is required in some states.
Medical payments and personal injury protection (PIP)
These coverages help pay medical bills for you and your passengers after an accident, regardless of fault. PIP is broader and may also cover lost wages and other expenses; it is required in no-fault states and optional in others. Medical payments (MedPay) is a simpler version focused on medical bills.
Common add-ons worth knowing
Beyond the core coverages, many carriers offer optional extras:
- Roadside assistance for towing, jump-starts, and lockouts
- Rental car reimbursement while your car is being repaired
- Gap insurance, which covers the difference between what you owe on a loan and the car’s value if it is totaled
- New-car replacement coverage for recently purchased vehicles
