S.C. Code § 12-28-1740
If a person is found operating a motor vehicle in violation of the shipping paper requirements in Sections 12-28-1505, 12-28-1540, 12-28-1545, and 12-28-1575, the vehicle and its cargo are subject to impoundment, seizure, and subsequent sale and forfeiture, in accordance with the general laws of this State respecting seizure and forfeiture. The failure of the operator of a motor vehicle to have on board when loaded a terminal-issued bill of lading with a destination state machine-printed on its face pursuant to Section 12-28-1505 or which fails to meet the descriptive annotation requirements of Sections 12-28-1540, 12-28-1545, and 12-28-1575, if applicable, is presumptive evidence of a violation sufficient to warrant impoundment and seizure of the vehicle and its cargo.
