Do I Need Insurance When I Buy A Car? 
It is recommended for sure and that really is up to the State , lender and the rules the auto dealer has in place . You should never drive any vehicle without insurance protection and in most cases is the law . That being said if you purchase a car and the party you are purchasing the car from does not require you to show proof of insurance or financial responsibility then you technically are just purchasing personal property in my opinion . I hope this helps and every states rules and regulations are different so please check .
