Can You Drive Your Friend's Car? Whose Insurance Pays If There's a Crash

Almost everyone has borrowed a car or lent one. It feels harmless, which is why it goes wrong so often. Here is who pays, what it can cost you, and the cases where your insurance may not cover the driver at all.

"Insurance follows the car" and what it means

When someone drives your car with your permission, your auto policy generally treats them as covered. This is called permissive use. The owner's policy is primary, meaning it pays first. The borrower's policy, if they have one, is secondary, meaning it can step in if the damage is larger than your limits.

That works in your favor if your friend has no insurance. It works against you when the friend causes a crash, because your policy is the one that takes the hit.

If your friend crashes your car

Say a friend borrows your car to pick up tacos and backs into a pole. Here is what usually happens:

• You pay your collision deductible. If you have collision coverage, your policy repairs your car minus your deductible. If you don't have collision, you pay for the repair yourself.
• If they hit someone else, your liability coverage pays the other driver's damage and injuries first, up to your limits.
• The claim goes on your policy. Whether your rates rise depends on the insurer and the claim. A claim paid on your policy can raise your premium even though you weren't driving. Experian says both the owner and the borrower may pay more if both policies pay. Jerry says an increase can range from a few dollars a month to more than 50%, and that it usually lasts about three years. Treat those as examples and not promises, since insurers set their own surcharges.
• If the damage is larger than your limits, the borrower's own policy may cover the rest. Experian gives an example: a crash causes $60,000 in damage, the owner's liability limit is $40,000, and the borrower's policy may cover the remaining $20,000. If the borrower has no policy, they could be personally responsible for that part. In some cases the owner can be sued too.

Your friend isn't automatically required to pay your deductible. You can ask them to, and it's smart to agree on that in writing before the keys change hands. If they refuse, small claims court is an option in many places, but that's a separate process from your insurance claim.

When your policy might not cover the driver

"Permission" doesn't guarantee coverage. These are the usual exceptions:

• An excluded driver. If you or an earlier policyholder named someone as an excluded driver, they have no coverage under your policy, even with your permission. You may be responsible for the damage, and your insurer may still raise your rate.
• Someone who borrows the car regularly. Permissive use is meant for occasional borrowing. A roommate or partner who uses your car often, or lives with you, may need to be listed on your policy. Some sources use about 12 uses a year as a rule of thumb, but insurers set their own rules, so ask yours.
• Driving without permission. If someone takes the car without asking, the owner's policy generally doesn't cover them. Permission can be implied, though, and if you handed over the keys without limits, an insurer might treat it as permission. If a friend takes your car and you didn't agree, report it and get a police report.
• A driver who isn't licensed or has a suspended license. Many policies exclude these drivers, and you could be personally liable for costs above your limits.
• Deliveries or rideshare. Standard personal policies exclude commercial use. If a borrower uses your car to drive for a delivery or rideshare app, your insurer may deny the claim.
• Peer to peer car sharing. If you rent your car out through a platform, your personal policy generally doesn't cover it unless the platform's own protection applies.
• Lending to someone you know is unsafe. Under negligent entrustment, an owner can be held liable for lending a car to someone they knew or should have known was unfit to drive, such as a person who was drunk or had a record of reckless driving or no license. Some states limit this, and the rules differ.

Some states also restrict or ban named driver exclusions, so check your state's rules before you assume an exclusion will hold. Our post on getting your own policy at 17 goes through how exclusions work state by state.

If you borrow a friend's car

The same rules apply in reverse:

• Ask first, and make sure the car is insured. If it isn't, you could be responsible for everything.
• Your friend's policy pays first. Your own policy may cover you as excess, if you have one. If you caused the crash and your policy pays anything, your rates could go up too.
• Know what your policy covers. Many personal policies extend liability coverage to cars you borrow, but not cars you use regularly or that live at your home. A non owner policy is liability only, so it doesn't pay to repair the car you're driving.
• Don't borrow the same car every week. If it's become routine, ask to be added to the owner's policy or get a policy of your own.

If you borrow cars often but don't own one, a non owner policy can fill the liability gap.

College students and roommates

This comes up constantly on campus, where one car often gets shared among friends:

• Add regular drivers. If a roommate or friend uses your car often, ask your insurer about adding them.
• Check the cost first. MoneyGeek puts a non owner policy at about $200 to $500 a year, and adding a listed driver at about $150 to $1,200 a year. Those are broad ranges, so ask for a real quote.
• Raise your liability limits if you lend your car. State minimums are low. A serious crash can cost much more than $25,000 for one person.
• Write down the rules. Who can drive, whether they pay the deductible, and whether anyone else can drive it.

A short checklist before you lend your car

• 1. Check that the driver has a valid license.
• 2. Confirm your policy is active and you have collision coverage if you want repairs covered.
• 3. Make sure they're not an excluded driver on your policy.
• 4. Tell them whether others can drive the car, and not to use it for deliveries or rideshare.
• 5. Agree on who pays the deductible if something happens.
• 6. If it's regular, add them to the policy.

The bottom line

Insurance usually follows the car, so lending yours means your policy is on the hook first, and you can end up with the deductible, the claim, and possibly a higher rate. Our post on why a rate can go up after a small claim explains how that part works. Check for excluded drivers, regular use and commercial use before you hand over the keys. If you borrow someone else's car, ask first and don't count on your own policy to pay for the damage.
