S.C. Code Ann. § 56-1-245

If a driver's license is suspended or revoked because the licensee is determined by the Department of Motor Vehicles to have no motor vehicle liability insurance, the department shall waive the reinstatement fee imposed pursuant to Section 56-1-390 if the licensee had motor vehicle liability coverage when his license was suspended or revoked. The director shall document his reasons for waiving the fee in the records of the department.
