Driving Someone Else’s Car: What You Need to Know About Insurance

Driving someone else’s car can be convenient, but it raises important questions about insurance coverage. Whether you’re borrowing a friend’s vehicle for a short trip or using a family member’s car regularly, understanding how insurance applies in these situations is crucial. This guide will explore the nuances of insurance coverage when driving someone else’s car, including liability, potential risks, and necessary precautions.

Insurance Basics for Driving Another Person’s Car
Primary Insurance Coverage
  • Owner’s Insurance: Typically, the insurance policy of the car owner is the primary coverage. This means that if you have an accident while driving someone else’s car, their insurance policy will generally cover the damages, assuming you have permission to drive the vehicle.
  • Liability Coverage: The car owner’s insurance should cover liability for any injuries or property damage you cause to others while driving their vehicle.
Secondary Insurance Coverage
  • Driver’s Insurance: If you have your own car insurance policy, it may act as secondary coverage. This can provide additional protection if the damages exceed the limits of the owner’s policy.
  • Non-Owner Car Insurance: If you frequently drive cars that you do not own, you might consider a non-owner car insurance policy. This type of policy provides liability coverage and sometimes includes uninsured/underinsured motorist coverage.

Potential Scenarios and Coverage

Borrowing a Friend’s Car

Occasional Use
  • Covered by Owner’s Policy: If you occasionally borrow a friend’s car, their insurance policy should cover you as a permissive driver. However, it’s crucial to confirm this with the car owner and their insurance provider.
Regular Use
  • Adding You as a Driver: If you regularly drive your friend’s car, it might be wise for the car owner to add you as a listed driver on their policy. This ensures that the insurance company is aware of your regular use, reducing the risk of denied claims.

Family Members’ Cars
Immediate Family
  • Household Policy: If you live with family members, their insurance policy typically covers you as an occasional driver. Parents’ insurance usually extends to their children, even if they are not listed drivers, provided they live in the same household.
  • Adult Children: If you are an adult child living at home, your parents should add you to their policy to avoid potential coverage issues.
Extended Family
  • Extended Coverage: For extended family members not living in the same household, it’s essential to check with the insurance provider. Coverage might still apply for occasional use, but it’s less clear-cut than immediate family situations.

Rental Cars
Rental Car Insurance
  • Rental Coverage: When renting a car, the rental company typically offers insurance options, including liability, collision, and comprehensive coverage. Check with your personal car insurance provider to see if your policy extends to rental cars.
  • Credit Card Coverage: Some credit cards offer rental car insurance as a benefit, covering collision damage and theft. This is often secondary to your primary insurance.

Risks and Considerations

Coverage Limits

Liability Limits
  • Owner’s Policy Limits: The owner’s insurance policy limits apply first. If the costs of an accident exceed these limits, you could be personally liable for the excess.
  • Supplemental Coverage: Your own insurance (if applicable) may cover additional costs, but it’s essential to understand the specifics of both policies.

Exclusions and Denials
Unauthorized Use
  • Permission Required: If you drive someone’s car without their permission, the insurance company may deny coverage for any claims arising from an accident.
  • Excluded Drivers: Some policies have excluded drivers—specific individuals not covered by the insurance. Ensure you are not an excluded driver under the car owner’s policy.

Commercial Use
  • Personal vs. Commercial: Using a personal vehicle for commercial purposes (e.g., ridesharing) without appropriate coverage can result in denied claims. Check for a rideshare endorsement or commercial policy.

Steps to Ensure Proper Coverage

Confirm Coverage Details

Discuss with Car Owner
  • Verify Policy: Before driving someone else’s car, discuss the insurance policy with the owner to confirm that you are covered as a permissive driver.
  • Understand Limits: Understand the coverage limits and whether they are sufficient for your needs.

Communicate with Insurance Providers
Notify Insurers
  • Primary Insurer: If you regularly drive another person’s car, notify both your insurer and the car owner’s insurer to ensure there are no coverage gaps.
  • Policy Adjustments: Consider any necessary adjustments, such as adding you as a listed driver on the owner’s policy.

Consider Additional Coverage
Non-Owner Insurance
  • Liability Coverage: If you frequently drive cars you don’t own, a non-owner insurance policy can provide liability coverage and protect against uninsured motorists.


Driving someone else’s car involves navigating insurance coverage that primarily depends on the car owner’s policy. While occasional use is generally covered, regular use might require additional steps, such as adding you as a listed driver. Always communicate with both the car owner and insurance providers to confirm coverage details and ensure there are no surprises in the event of an accident. By understanding these intricacies, you can drive with confidence and peace of mind.
