Car Insurance Coverage Types, Explained Plainly

An auto insurance policy is not one thing. It is a bundle of separate coverages, each with its own job, its own limit and sometimes its own deductible. Once you can name the pieces, a policy stops looking like a wall of fine print and starts looking like a short list of decisions. Here is each common coverage, what it pays for, and what it does not.

Liability coverage

Liability is the heart of the policy and the part nearly every state requires. It pays for harm you cause to other people when you are at fault. It comes in two parts:

• Bodily injury liability pays for other people's medical bills, lost wages and related costs if you injure them in a crash, along with your legal defense if you are sued.
• Property damage liability pays to repair or replace what you damage: another car, a fence, a mailbox, a storefront.

Liability never pays to fix your own car or treat your own injuries. Limits are usually written as three numbers, such as 50/100/50, which we explain in our Teaching on liability limits.

Collision coverage

Collision pays to repair or replace your own vehicle after it hits another vehicle or an object, such as a guardrail, a pole or a wall. It also typically applies if your car rolls over. It pays regardless of who caused the crash, minus your deductible. If another driver was at fault, your insurer may later try to recover what it paid from that driver's insurer, a process called subrogation.

Collision is optional under state law, but if you finance or lease the car, your lender or leasing company will almost always require it.

Comprehensive coverage

Comprehensive, sometimes called "other than collision", covers damage to your car from events that are not a crash with another car or object. Common examples include theft, vandalism, fire, hail, flooding, falling trees and hitting an animal such as a deer. Like collision, it has a deductible, it is optional by law, and lenders usually require it.

Uninsured and underinsured motorist coverage

Uninsured motorist coverage (UM) protects you when an at-fault driver has no insurance at all, and in many states when the at-fault driver is a hit-and-run driver who is never identified. Underinsured motorist coverage (UIM) helps when the at-fault driver has insurance, but not enough to cover your losses. Some states require these coverages, while others require insurers to offer them and let you decline in writing. Our uninsured motorist Teaching goes deeper.

Personal injury protection and medical payments

Personal injury protection (PIP) pays medical expenses for you and your passengers after a crash, no matter who was at fault. Depending on the state, it can also cover a portion of lost income and essential services you cannot perform while injured. PIP is required in states that use a "no-fault" system and is optional or unavailable in others.

Medical payments coverage (MedPay) is a simpler, usually smaller coverage that pays medical bills for you and your passengers regardless of fault. It is commonly offered in states that do not require PIP. It can help with health insurance deductibles and copays after an accident.

Optional add-ons

Most insurers offer extra coverages that you can add for an additional premium. The most common are:

• Rental reimbursement, which helps pay for a rental car while yours is being repaired after a covered claim, usually up to a daily and total limit.
• Roadside assistance, which can cover towing, jump starts, lockouts, flat tire changes and fuel delivery.
• Gap coverage, which can pay the difference between your car's value and what you still owe on a loan or lease if the car is totaled. See our gap insurance Teaching.
• New car replacement or better car replacement, offered by some insurers, which may pay toward a new vehicle instead of the depreciated value if a fairly new car is totaled.
• Custom equipment coverage for aftermarket parts, such as upgraded wheels or audio systems, which standard policies may cover only up to a small amount.

What a typical policy does not cover

It is just as calming to know the boundaries. Standard personal auto policies generally do not cover normal wear and tear, mechanical breakdown, or damage from poor maintenance. Personal belongings stolen from your car are usually a matter for homeowners or renters insurance, not auto insurance. Using your personal car to deliver food or drive for a rideshare service may not be covered without a specific endorsement, so ask before you start that kind of work.

Putting the pieces together

A simple way to think about it: liability protects other people from you, collision and comprehensive protect your car, and UM, UIM, PIP and MedPay protect you and your passengers. The add-ons smooth out the inconvenience. When you look at a quote, find each piece, note its limit and deductible, and ask yourself whether it fits your car, your finances and your daily driving. That is the whole practice.
