S.C. Code Ann. § 56-5-4160
(C) A person who operates a vehicle found to exceed the excess gross weight limitations imposed by Section 56-5-4130 or 56-5-4140 is guilty of a misdemeanor and, upon conviction, shall pay to the Department of Public Safety a fine based on the following scale:
(3) 6,001 pounds and over: ten cents per pound over weight limit, beginning with the first pound in excess.
The fine imposed pursuant to items (1) and (2) must be equal to one-half the rate for vehicles transporting raw farm or forest products from the farm or forest to the first market, or by fully enclosed motor vehicles designed specifically for collecting, compacting, and hauling garbage from residences or from garbage dumpsters, or by motor vehicles operating open top trailers used for hauling recyclables, scrap, and waste materials from sites without facilities for weighing, when operating for those purposes. If an operator is found to be in violation of both gross and axle limits, only one citation may be issued, the fine being for the greater of the two, for that load. No fine may be issued for violation of the vehicle registration statues if that vehicle is registered for the maximum allowable weight for that class of vehicle as provided in Section 56-5-4140.
If the operator of the vehicle, upon conviction, fails to remit the fine imposed by this subsection to the Department of Public Safety, the owner of the vehicle is responsible for remitting the fine. The court is prohibited from suspending any portion of this fine.

(F) Magistrates have jurisdiction of all contested violations of this section. All monies collected pursuant to Section 56-5-4160 must be forwarded to the Department of Public Safety as provided for in this section. A magistrate, within forty-five days, must forward all monies collected to the department for deposit in the account established in this section. The department shall use these monies to establish and maintain automated data bases, to upgrade and refurbish existing weigh stations, to purchase and maintain portable scales, to hire additional State Transport Police Officers, to purchase equipment for State Transport Police Officers, and to procure other commercial motor vehicle safety measures, and fund other commercial motor vehicle safety programs that the department considers necessary. The fine may be deposited with the arresting officer or a person the department may designate. The fine must be deposited in full or other arrangements satisfactory to the department for payment must be made before the operator is allowed to move the vehicle. If there is no conviction, the fine must be returned to the owner promptly.
"Conviction", as used in this section, also includes the entry of a plea of guilty or nolo contendere and the forfeiture of bail or collateral deposited to secure a defendant's presence in the court.
If the fine is not paid in full to the Department of Public Safety within forty-five days after conviction, the license and registration of the vehicle found to violate Section 58-23-1120 or Regulations 38-423 et seq. or exceed the limits imposed by Section 56-5-4130 or 56-5-4140 must be suspended. The owner of the vehicles immediately shall return the license and registration of the vehicle to the Department of Motor Vehicles. If a person fails to return them as provided in this section, the Department of Motor Vehicles may secure possession of them by a commissioned trooper or officer. The suspension continues until the fine is paid in full.
