What Car Insurance Covers and How It Works

Car insurance is a contract between you and an insurance company that pays for damage or injury caused by a car accident, theft, or weather

When you buy car insurance, you pay a monthly or annual premium. In return, the insurance company agrees to pay certain costs if you have an accident, your car is stolen, or specific events damage your vehicle. The insurance company does not pay for everything — the policy spells out what it covers, what it does not, and how much you have to pay out of pocket before the company pays anything.

Most states require you to carry at least a minimum amount of liability insurance before you can legally drive. Liability insurance pays for damage or injury you cause to someone else. If you have a loan on your car, your lender will require you to carry collision and comprehensive coverage as well. If you own your car outright, those types are optional.

Key Takeaways

• Liability insurance pays for damage or injury you cause to another person or their property, and most states legally require it.
• Collision and comprehensive coverage pay for damage to your own car from accidents, theft, weather, or vandalism, but only if you choose to buy them.
• You choose a deductible — the amount you pay out of pocket — and a coverage limit, which is the maximum the insurance company will pay.
• Your premium depends on your age, driving record, the type of car, where you live, and how much coverage you buy.

The main types of car insurance coverage and what they pay for

Liability insurance covers damage or injury you cause to someone else. It has two parts: bodily injury liability pays for medical bills and lost wages if you injure another person; property damage liability pays to repair or replace their vehicle or other property. If you cause a serious accident, liability claims can be expensive, so most people buy more than the state minimum.

Collision insurance pays to repair or replace your car if you hit another vehicle or object — a tree, a telephone pole, a guardrail. It pays regardless of who caused the accident. If your car is worth very little, collision coverage may cost more than the car is worth, so many owners of older cars skip it.

Comprehensive insurance pays for damage to your car from events other than collisions: theft, vandalism, weather (hail, flooding, wind), hitting an animal, or a falling object. Like collision, it is optional unless you have a loan on the car.

Uninsured and underinsured motorist coverage pays for your medical bills and car damage if you are hit by a driver who has no insurance or not enough insurance to cover your costs. The rules about whether this is required vary by state.

How deductibles and coverage limits work

When you buy a policy, you choose a deductible — the amount you pay toward a claim before the insurance company pays the rest. Common deductibles are $250, $500, $1,000, or $2,500. A higher deductible means a lower monthly premium, but you pay more out of pocket if you have a claim. A lower deductible means a higher premium, but less money out of your pocket when you need to file a claim.

You also choose a coverage limit — the maximum amount the insurance company will pay for a single claim. For liability, limits are usually written as three numbers, like 25/50/25, which means $25,000 per person for bodily injury, $50,000 total per accident for bodily injury, and $25,000 for property damage. If your claim exceeds your limit, you pay the difference yourself.

For collision and comprehensive, the coverage limit is usually the actual cash value of your car — what it would sell for today, not what you paid for it. If your car is worth $8,000 and you cause $10,000 in damage, the insurance company pays $8,000 minus your deductible.

What affects your insurance premium

Insurance companies use several factors to calculate your monthly or annual premium. Your age and driving record are major ones — younger drivers and those with accidents or traffic violations pay more. The type of car matters: a sports car costs more to insure than a sedan, and a car with expensive parts costs more than one with cheap parts.

Where you live affects your premium because some areas have more accidents, theft, or weather damage. Urban areas often cost more than rural ones. Your credit score can also play a role — in most states, insurers can use credit information to set rates. How much coverage you buy, your deductible, and whether you bundle car insurance with home or renters insurance can lower your premium.

How to file a claim when you have an accident

If you are in an accident, call your insurance company as soon as safely possible. Have your policy number ready. The company will ask for details about what happened, where, and when. Take photos of the damage to your car and the other vehicle if there is one. Get the other driver's name, phone number, address, insurance company, and policy number. If there are witnesses, get their contact information too.

The insurance company will assign an adjuster to inspect the damage and estimate the cost of repairs. You can take your car to a repair shop of your choice — the insurance company does not get to pick it. Once the adjuster approves the estimate, the repair shop can begin work. The insurance company pays the repair shop directly, and you pay your deductible.

The difference between actual cash value and agreed value

Most car insurance policies pay based on actual cash value, which is what your car would sell for on the used car market today. This amount goes down every year as your car ages. If your car is totaled, the insurance company pays the actual cash value minus your deductible, even if you still owe money on a loan.

Some insurance companies offer agreed value coverage, usually for classic or collector cars. You and the insurance company agree in advance on what the car is worth, and that is what they pay if it is totaled. This costs more but protects you if the car has special value beyond what the market would pay.

Frequently Asked Questions

Do I have to buy collision and comprehensive insurance?

Only if you have a loan or lease on your car — your lender requires it to protect their investment. If you own your car outright, both are optional. Many people with older cars skip them because the premium costs more than the car is worth.

What happens if I let my insurance lapse?

Driving without insurance is illegal in every state. If you are caught, you face fines, license suspension, and possibly jail time depending on the state. If you cause an accident while uninsured, you are personally responsible for all costs, which can include the other person's medical bills and car damage.

Can I lower my insurance premium?

Yes. Raise your deductible, drop collision or comprehensive if you own your car outright, bundle with home or renters insurance, ask about discounts for good driving or safety features, and shop around — rates vary widely between companies for the same coverage.

What is a grace period if I miss a payment?

Most insurance companies give you 10 to 30 days after your payment is due before they cancel your policy. Check your policy documents for the exact number. If you miss the important date, your coverage ends and you are driving illegally.

Does my insurance cover me if someone else drives my car?

Usually yes, as long as they have your permission. Your insurance follows the car, not the driver. However, if you regularly let someone else drive your car, tell your insurance company — they may adjust your rate or ask you to add that person to the policy.
