S.C. Code § 56-9-350
The operator or owner of a motor vehicle involved in an accident resulting in property damage of four hundred dollars or more, or in bodily injury or death, must be furnished a written request form at the time of the accident, or as soon after the accident as possible, by the investigating officer for completion and verification of liability insurance coverage, the form to be in a manner prescribed by the Department of Motor Vehicles and the Department of Public Safety.
The completed and verified form must be returned by the operator or owner to the Department of Motor Vehicles within fifteen days from the date the form was delivered by the officer. Failure to return the form, verified in the proper manner, is prima facie evidence that the vehicle was uninsured.
The operator or owner of a motor vehicle involved in an accident resulting in property damage of four hundred dollars or more, or in bodily injury or death, which was not investigated by a law enforcement officer shall furnish to the Department of Motor Vehicles a written report and verification of liability insurance coverage, the proof to be in a manner prescribed by the Department.
