S.C. Code Ann. § 56-16-180
Any license issued under this chapter may be denied, suspended, or revoked if the applicant or licensee or an agency of the applicant or licensee acting for the applicant or licensee is determined by the Department of Motor Vehicles to have:
(h) Given, loaned, or sold a dealer license plate to any person or otherwise to have allowed the use of any dealer license plate in any way not authorized by Section 56-3-2320. Any dealer license plate issued to a dealer or wholesaler pursuant to Section 56-3-2320 which is determined by the Department to be improperly displayed on any motorcycle or in the possession of any unauthorized person is prima facie evidence of a violation of this section by the dealer or wholesaler to whom the license plate was originally issued.
The Department shall notify the licensee or applicant in writing at the mailing address provided in his application of its intention to deny, suspend, or revoke his license at least twenty days in advance and shall provide the licensee an opportunity for a hearing pursuant to the Administrative Procedures Act of this State. A licensee desiring a hearing shall request it in writing within ten days of receiving notice of the proposed denial, suspension, or revocation of his dealer's or wholesaler's license.
Upon the denial, suspension, or revocation of a license, the licensee shall immediately return to the Department the license and all dealer license plates.
