Final answer:
When cancelling insurance coverage and not maintaining liability insurance on a vehicle, it is the responsibility of the owner to surrender the license plate(s) and registration certificate(s) to the local SCDMV office.
Step-by-step explanation:
When cancelling insurance coverage, it is the responsibility of the vehicle owner to surrender the license plate(s) and registration certificate(s) to their local SCDMV office if liability insurance is not being maintained on their vehicle. This is because liability insurance is required by most states to legally operate a vehicle. By surrendering the license plate(s) and registration certificate(s), the owner notifies the SCDMV that the vehicle is no longer insured and will not be on the road.
