S.C. Code Ann. § 50-9-1150: Notice of suspension; appeals.

(A) Upon determination that a person has accumulated sufficient points to warrant suspension of privileges, the department shall notify him in writing that his privileges are suspended, and the person shall return the license and any tags in the person's name to the department no later than ten days following the effective date of the suspension.

(B) The notice of the suspension must be given by the department by depositing the notice in the United States mail with postage prepaid addressed to the person at the address contained in the records of the department. The giving of notice by mail is complete twenty days after the deposit of the notice. A certificate by the director of the department, or his designee, that the notice has been sent as required in this section is presumptive proof that the requirements as to notice of suspension have been met even if the notice has not been received by the addressee.

(C) A person whose privileges have been suspended may appeal the decision of the department under the Administrative Procedures Act.
