You can drive someone else’s car without your own insurance. The car owner’s insurance usually covers you if you have permission to drive. Since insurance follows the vehicle, their policy typically handles damage in an accident, but coverage depends on the policy’s terms and limits.
If you have auto insurance, it may provide secondary coverage, offering additional protection if the owner’s policy isn’t enough.
Be aware of permissive use clauses. Most policies allow occasional borrowing, but regular use without being listed could lead to denied claims, leaving the owner responsible for costs.
