The core coverage types explained
Auto insurance is sold in layers. Most drivers carry several coverage types on a single policy, each doing a different job. Knowing what each one covers, and what it does not, helps you make informed decisions rather than guessing when something goes wrong.
Liability coverage
Pays for injuries and property damage you cause to others in an at-fault accident. Does not cover your own vehicle or injuries.
Collision coverage
Pays to repair or replace your vehicle after a collision with another car or object, regardless of who is at fault.
Comprehensive coverage
Covers vehicle damage from non-collision causes such as theft, weather, fire, or animal strikes.
Deductible
The amount you pay out of pocket before your insurance covers the rest of a claim. A higher deductible generally means a lower premium.
Gap coverage
Pays the difference between your vehicle's market value and your remaining loan or lease balance if the vehicle is totaled.
Personal injury protection (PIP)
Covers medical expenses and sometimes lost wages for you and your passengers after an accident, regardless of fault. Required in no-fault states.
Liability coverage
Liability is the foundation of almost every auto policy in the US, and most states require it by law. It pays for injuries and property damage you cause to others in an accident where you are at fault. It does not pay for your own injuries or vehicle damage.
Liability limits are written as three numbers, such as 25/50/25. Those figures represent, in thousands of dollars: per-person bodily injury, per-accident bodily injury, and property damage. State minimums are often low enough that a serious accident can exceed them, leaving you responsible for the remainder.

Collision coverage
Collision pays to repair or replace your vehicle after an accident with another car or a stationary object, regardless of fault. If you hit a guardrail or are struck by another driver and that driver is uninsured, collision is what covers your car. It applies after you pay your deductible.
Comprehensive coverage
Comprehensive covers vehicle damage from causes other than a collision: theft, vandalism, falling objects, fire, flooding, and animal strikes. Like collision, it applies after your deductible. Lenders and leasing companies typically require both collision and comprehensive while you finance a vehicle.

Uninsured and underinsured motorist coverage
Uninsured motorist (UM) coverage pays for your medical bills and, in some states, vehicle damage when the at-fault driver carries no insurance. Underinsured motorist (UIM) coverage applies when the at-fault driver has insurance but their limits are too low to cover your costs. The Insurance Research Council has reported that a notable share of US drivers carry no insurance at any given time, making UM/UIM coverage worth serious consideration even where it is not mandatory.
Personal injury protection and medical payments
Personal injury protection (PIP) covers medical expenses for you and your passengers after an accident, without regard to fault. In no-fault states, PIP is required. Medical payments (MedPay) is a narrower version available in fault-based states that covers medical bills but typically not lost wages or other expenses PIP might include.
Gap coverage
If your vehicle is totaled, your insurer pays its current market value, which can be less than what you still owe on a loan or lease. Gap coverage pays the difference between the settlement and your outstanding balance. It is most relevant in the early years of financing, when depreciation outpaces payoff.
