As you shop for the best non-owner car insurance policy, consider the cost, limits, and customer experience. Here’s how to find the right fit.

What is non-owner car insurance in California, and who needs it?

Non-owner coverage is car insurance for drivers without a car. It provides protection when you drive someone else’s vehicle. The coverage is more limited than other policies since it covers only liability for property damage and injuries. The car owner’s coverage kicks in after an accident, so you don’t need extra coverage as a non-owner.

For example, let’s say you borrow a friend’s car regularly. Your friend’s insurance policy has a $30,000 limit for property damage. While you’re driving, you cause an accident that results in $50,000 of damages to the other driver’s car. Your friend’s insurance would cover $30,000 of the damage, and your non-owner policy would cover the remaining $20,000.

Drivers must have insurance coverage in California, and in most cases, non-owner insurance is one way to meet the legal requirement.1 But it isn’t optional when you need SR-22 insurance and don’t own a car, since non-owner insurance is the only way to make sure you have continuous coverage.
