Normally if you borrow a person's vehicle their liability insurance is extended to you. If you are stopped in a friend's car for a traffic violation then showing the car owner's insurance card typically is enough proof of insurance for law enforcement officers.

If the car you are driving was uninsured there would be penalties though. If you are stopped by a SC law enforcement officer and are unable to provide proof that the vehicle you are operating is insured, you may be issued a citation and be subject to a fine or imprisonment.

If issued a citation, you will be required to provide proof of insurance for the vehicle that you were operating at the time within thirty (30) days to avoid an indefinite suspension of your driver’s license.

If you fail to maintain proof of insurance on the motor vehicle you are guilty of a misdemeanor and may face suspension action by the SC Department of Motor Vehicles. Penalties can include the owner’s driver license and vehicle registration being suspended and he or she may have to pay $5.00 for each day the vehicle was uninsured, up to $200.00, plus an additional $200.00 reinstatement fee.

To make certain that while driving someone else's vehicle that the owner's insurance card is enough to show to the police if pulled over for a traffic violation contact the SC DMV or local police station.
