Can You Drive Someone Else's Car Without Insurance?

You usually don’t need your own insurance to drive someone else’s car if you have their permission and their car is insured. Most auto policies include permissive use, which means the car owner’s insurance provides financial protection when you borrow the vehicle occasionally. Because insurance follows the car, their liability coverage applies if you cause an accident.  

Permissive use only applies for infrequent borrowing. If you drive the car regularly, live in the same household or use it for work or deliveries, insurers may require you to be listed on the policy. Violating any of the following permissive use exclusions means that coverage can be denied in a claim:  

• Household members: Anyone living with the car owner must be listed on the policy
• Regular users: Drivers who use the same car 12 or more times per year need to be added to the policy
• Excluded drivers: Drivers with poor records or suspended licenses are not covered
• No permission: Driving the car without the owner's consent voids all coverage and counts as vehicle theft
• Commercial or rideshare use: Using someone else's car for deliveries or rideshare driving falls outside their policy's permissive use coverage entirely, even with permission. A separate rideshare or commercial policy is required.

Non-owner car insurance covers you when you regularly drive vehicles you don't own and the owner's policy doesn't extend to you. It provides personal liability protection for those situations.

Borrowing a car means the owner's insurance applies to you under their liability, collision and comprehensive coverages, provided you have their express permission. Their liability coverage pays for injuries or damage you cause to others and carries no deductible. Collision coverage, if the owner has it, pays for damage to the car, no matter who caused the crash. Comprehensive covers theft or vandalism that happens while you have the vehicle.   

The owner's policy acts as your primary coverage. If the damages exceed the owner's coverage limits, your own policy (if you have one) would then provide secondary coverage. If neither policy has high enough coverage limits to pay for the damages, the extra cost comes out of your pocket.

Your exposure scales with how low the owner's liability limits are. For example, if you cause a $150,000 accident and the owner's bodily injury limit is $50,000, the remaining $100,000 isn't covered by their policy. If you don't carry your own insurance to absorb that difference, you can be personally sued for it.  

The example above isn't exaggerated: the most typical state minimum liability requirement is just $25,000 per person and $50,000 per accident, which a single serious hospitalization can exceed. Florida requires no bodily injury coverage at all. 

Before assuming you're fully covered as a borrower, it's worth asking whether the owner carries more than their state's minimum.

You need your own car insurance when you drive someone else's car more than 12 times per year, live in the same household as the owner or frequently borrow different vehicles. Permissive use coverage only applies to occasional borrowing and excludes household members and regular users.

You can drive someone else's car without your own insurance if their policy includes permissive use and you have their permission. The rules shift for household members, regular users and excluded drivers. Coverage can even be voided in some cases.

When you borrow a car, the owner's policy typically pays first, as primary insurance. It covers damages up to its limits, collision coverage for damage to the borrowed car and comprehensive coverage for non-collision incidents like theft or vandalism. Your own policy, if you have one, kicks in second. It covers any remaining liabilities or damages the owner's primary policy doesn't fully pay.

Before borrowing any vehicle, confirm the owner has active insurance and check that you're not excluded from the policy. Know your state's requirements too. Borrowing cars more than once a month? Look into non-owner insurance.

Drivers who've been uninsured have fewer options than standard shoppers. They often need high-risk driver coverage. A DUI or suspended license means higher premiums and fewer choices, and the same holds for drivers who went without coverage for six months or longer.
