What Is Car Insurance?
Car insurance provides financial protection for drivers in case of vehicle damage, personal injury or theft. Without car insurance, drivers would be at risk of financial ruin every time they get behind the wheel, as severe collisions can cost hundreds of thousands of dollars in property damage and bodily injuries. Coverage is required in almost every state, and you get this protection from a car insurance company in exchange for paying an insurance premium.
The various types of car insurance coverage all work a bit differently, depending on which driver is found to be at fault, what type of damage is caused, and what state the accident occurs in.
What Does Car Insurance Cover?
Most minimum coverage car insurance policies cover injuries and property damage that you cause others. However, you can add optional types of insurance that cover things like your injuries and property damage, along with roadside assistance and rental reimbursement.
Bodily injury liability insurance
Bodily injury liability insurance covers any medical bills that other people might have after a collision where you’re at fault. It is required in most states.
Property damage liability insurance
Property liability insurance covers damage that you cause to other people’s property with your car. It is required in most states.
Medical payments (MedPay) coverage
Medical payments coverage helps pay for your medical bills after an accident. It is required in some states.
Personal injury protection (PIP) insurance
Personal injury protection insurance helps with your medical bills and certain other costs after an accident, regardless of who is at fault. It is required in some states.
Collision insurance
Collision insurance can help repair your vehicle after an accident with another car. Collision coverage combined with comprehensive insurance is often called “full coverage.” It is optional.
Comprehensive insurance
Comprehensive insurance covers non-accident related damage such as vandalism and fallen tree branches landing on your vehicle. It is optional.
Gap insurance
Gap insurance helps drivers pay off the rest of their car loan if their vehicle is totaled or stolen. It is optional.
Roadside assistance
Roadside assistance coverage reimburses you for services like towing and flat-tire replacement. It is optional.
Rental reimbursement
Rental reimbursement covers the cost of a rental car while your damaged car is being repaired after a collision. It is optional.
Uninsured motorist coverage
Uninsured motorist coverage pays for your medical and property damages when an uninsured driver is at-fault in an accident you’re involved in. Underinsured motorist coverage covers you when the at-fault driver is insured but does not have adequate coverage.
Classic car insurance
Classic car insurance covers vehicles that are at least 20 or 25 years old. It provides similar coverage to normal car insurance but often comes with a mileage limit which keeps the vehicle from everyday driving.
New-car replacement
New-car replacement insurance replaces your car with a new car of a similar make and model when your car is deemed totaled. It is optional.
Mechanical breakdown insurance
Mechanical breakdown insurance provides coverage for the major systems in your car like engine and transmission. It is sometimes referred to as car repair insurance. It is optional.
Rideshare insurance
Rideshare insurance increases a driver's coverage and lowers their deductible for accidents that occur when driving for ridesharing companies like Lyft and Uber. It is optional.
How Car Insurance Works When You Are At Fault
When you are at fault in an accident, the other driver will file a claim with your liability insurance to have their medical expenses and vehicle repairs paid for. If you also need your medical costs and property damage covered, you’ll have to file a claim with your own collision insurance, personal injury protection, or MedPay.
Before you can have your collision insurance cover your vehicle repairs, you’ll likely need to pay a deductible. Deductibles are the amount of money you have to pay before your insurer will cover the rest of a claim. Personal injury protection, uninsured motorist, and comprehensive insurance all usually have a deductible, as well.

How Car Insurance Works When You Are Not At Fault
When you are not at fault for an accident in most states, the at-fault driver’s liability insurance pays to cover your medical expenses and vehicle repairs.
No-fault states are the exception, requiring you to use your own car insurance (personal injury protection) to pay for your medical bills after an accident. The at-fault driver’s insurance will still pay for your vehicle repairs, though.
If the at-fault driver does not have any insurance, or if their liability insurance is not enough to cover your costs, you can file a claim with your own uninsured motorist insurance.

How Car Insurance Works When Fault Is Unclear
When you file a claim, either with your own insurance company or with someone else’s, the insurance company will send an adjuster to investigate the incident and make an official determination of fault. This process can sometimes take a while, so if you need your vehicle repairs covered before fault can be determined, you can still file the claim with your own collision insurance. If you are later found to not be at fault, your insurance company will try to recover those costs, including your deductible, from the other driver’s insurer through a process called subrogation.
If both drivers share fault in an accident, which insurance company pays for the claims is determined by the state’s negligence laws. In Virginia, for example, drivers who are even slightly found to be at fault cannot receive any compensation for their expenses from the other driver. California, however, allows drivers to collect damages based on their percentage of the shared fault.

How Much Car Insurance Do You Need?
Car insurance is required in 49 of the 50 states, and New Hampshire is the only exception. Anyone who owns and drives a car needs to prove that they have coverage in order to avoid costly penalties. If you’re caught driving without insurance, you can face fines, lose your license, or even go to jail. Some states do allow you to make a cash deposit in place of buying car insurance, but it usually has to be between $40,000 and $155,000.
Most states only require drivers to have liability insurance, while others require additional coverage like personal injury protection and uninsured motorist coverage. You only have to meet the state-minimum requirements, but it’s recommended that you buy as much coverage as you can comfortably afford since the minimum coverage limits typically don’t provide enough protection against severe accidents.
