S.C. Code Ann. § 56-1-80
(A) Every application for a driver's license or permit must:
(C) Whenever an application is received from a person previously licensed or permitted in another state, the Department of Motor Vehicles may request a copy of the applicant's record from the other state. When received, the record becomes a part of the driver's record in this State with the same effect as though entered on the operator's record in this State in the original instance. Every person who obtains a driver's license or permit for the first time in South Carolina and every person who renews his driver's license or permit in South Carolina must be furnished a written request form for completion and verification of liability insurance coverage.
The completed and verified form or an affidavit prepared by the department that neither he, nor a resident relative, owns a motor vehicle subject to the provisions of this chapter, must be completed and delivered to the department at the time the license or permit is issued or renewed.
