Liability Coverage
Liability coverage helps pay for injuries or damage you cause to other people in an accident. It usually includes bodily injury liability and property damage liability. It protects your finances if you are at fault, but it does not pay to fix your own car.
Collision Coverage
Collision coverage helps pay to repair or replace your car after an accident, regardless of who caused it. It usually applies when you hit another vehicle or an object like a pole or guardrail. In most cases, you pay your deductible first, and then your insurance helps cover the rest.
Comprehensive Coverage
Comprehensive coverage helps pay for damage caused by things other than a crash. That can include theft, hail, fire, vandalism, falling objects, or hitting an animal. It covers different risks than collision coverage, even though the two are often bundled together.
Deductible
A deductible is the amount you pay out of pocket before your insurance starts paying on a covered claim. For example, if your deductible is $500, you pay that part first. A higher deductible often means a lower premium, but it also means more cost to you when you file a claim.
Premium
A premium is the price you pay for your insurance policy. You may pay it monthly, every six months, or once a year. The amount depends on things like your car, driving record, location, age, and the coverage you choose.
Policy Limit
A policy limit is the maximum amount your insurance company will pay for a covered claim. Different types of coverage can have different limits. If costs go above your limit, you may have to pay the difference yourself.
Uninsured Motorist Coverage
Uninsured motorist coverage helps protect you if a driver with no insurance causes an accident. Depending on your state and policy, it may help pay for injuries, lost wages, and sometimes vehicle damage. It can be especially helpful when the at-fault driver cannot cover the costs.
Underinsured Motorist Coverage
Underinsured motorist coverage helps when the other driver has insurance, but not enough to pay for all of your losses. It can help cover the gap after the at-fault driver’s limits are used up. This coverage may help with medical bills and other covered expenses.
Gap Insurance
Gap insurance helps pay the difference between what your car is worth and what you still owe on your loan or lease if the car is totaled or stolen. This matters because cars can lose value faster than loan balances go down. Without gap insurance, you could still owe money on a car you no longer have.
Rental Reimbursement
Rental reimbursement helps pay for a rental car while your vehicle is being repaired after a covered claim. It usually comes with daily and total dollar limits. It is optional coverage, but it can be useful if you depend on your car every day.
