Can You Drive Any Car On A Fully Comprehensive Insurance? 
Insurance follows the car . If you are involved in an accident the insurance on that car will be the primary coverage for a claim . Your policy may provide secondary coverage if the claims exceeds the limits of the policy covering the car . If you are driving a car that is rented you will be covered to the limits of your policy . The key is that the insurance is on the car not you , the driver . Make sure that the car is insured first .
