- Insurance generally follows the car, not the driver. If you drive someone else’s car with permission, the vehicle owner’s insurance is typically responsible first for claims.
- Your own policy can provide secondary coverage if damages exceed the owner’s liability limits, including uninsured/underinsured motorist coverage or medical payments.
- Permission matters. Coverage may be denied if you drive the car without the owner’s explicit consent (non‑permissive use).
- Some policies exclude permissive drivers. Certain insurers may not extend full coverage to non‑named drivers — check for exclusions or limitations before you borrow a car.
- Non‑owner car insurance exists for people who frequently borrow vehicles they don’t own and want their own liability coverage.
If you’re thinking about borrowing a friend’s car or letting someone drive yours, one question likely comes up: Who’s actually covered if something goes wrong?
While it might seem like insurance follows the driver, the truth is more complex — and making the wrong assumption could cost you. Here’s what to know before you get behind the wheel of someone else’s vehicle.
How does auto insurance works when you drive someone else’s car?
When you drive a vehicle you don’t own, whether you’re covered depends primarily on insurance policy structure and permission. In the U.S., auto insurance coverage generally follows the car first and the driver second. This means:
- The owner’s insurance policy is usually the primary coverage for liability and many other coverages if you have the owner’s consent to drive.
- If damages exceed the owner’s liability limits, your own auto policy (if you have one) may act as secondary coverage to help cover remaining costs.
Permission is the key: What “permissive use” means?
Most personal auto policies include a concept called permissive use — that is, the owner has given you permission to drive their car.
- Permissive use typically allows the owner’s insurance to cover an accident while you’re driving.
- If you drive without permission (non‑permissive use), that owner’s coverage may not apply, and you could be personally liable for damages.
Always ask the owner beforehand and confirm that their insurer will extend coverage to you.
What your own auto insurance does when borrowing a car
Even though the owner’s policy is primary, your own car insurance can still matter:
- If the accident costs more than the owner’s liability limits, your liability coverage may help cover the difference.
- Your uninsured/underinsured motorist coverage may apply if the at‑fault driver lacks adequate coverage.
- Some policies include non‑owned vehicle coverage or endorsements that extend collision and comprehensive coverage to borrowed cars — but this varies by insurer.

When insurance might not cover you
There are several situations where insurance could be limited or denied when driving someone else’s vehicle:
- No permission: Driving without the owner’s consent can void the owner’s coverage.
- Policy exclusions: Some policies exclude coverage for drivers who regularly borrow the vehicle but aren’t listed on the policy.
- Lapsed or inadequate coverage: If the owner’s policy is inactive or doesn’t include certain coverages, you might be undercovered. Checking both policies before driving helps reduce surprises.
Alternatives: Non‑owner car insurance
If you frequently borrow other people’s vehicles, consider non‑owner car insurance.
- This type of policy provides liability coverage when you drive vehicles you don’t own.
- It doesn’t insure a specific car, so collision and comprehensive typically won’t apply — but it can fill gaps if you drive someone else’s car often.
Non‑owner coverage can help protect you from large out‑of‑pocket liability costs and keep continuous coverage on your record.
Frequently Asked Questions: Borrowing vehicles
If I borrow a friend’s car, whose insurance pays first in an accident?
Generally, the owner’s insurance policy pays first (primary coverage) if you have the owner’s permission. Your own policy may act as secondary coverage if needed.
Am I covered if I drive someone’s car without permission?
No — if you drive without the owner’s consent (non‑permissive use), the owner’s insurance likely won’t cover you, and you could be responsible for all damages.
Will my own insurance increase if I crash a borrowed car?
If the owner’s insurance is used for the claim, their rates may increase. Your own rates could be affected if your policy is secondary on the claim or if you frequently drive other cars.
Does my insurance always cover me in another person’s vehicle?
Not always. It depends on the specific terms of both your own and the owner’s policy, including coverage limits and any exclusions. Always verify coverage before driving.
What is non‑owner car insurance and should I get it?
Non‑owner insurance provides liability coverage when you drive vehicles you don’t own. It’s a good option if you frequently borrow cars and want added financial protection beyond the owner’s policy.
