S.C. Code Ann. § 56-1-650

(A) A state that is a member of the Drivers License Compact shall report to another member state of the compact a conviction for any of the following: (1) manslaughter or homicide resulting from the operation of a motor vehicle as provided by Sections 56-1-280 and 56-5-2910; (2) driving a motor vehicle while under the influence, as provided by Section 56-5-2930; (3) any felony in the commission of which a motor vehicle is used, as provided by Section 56-1-280; (4) failure to stop and render aid in the event of a motor vehicle accident resulting in the death or personal injury of another, as provided by Section 56-5-1210. (B) If the laws of a member state do not describe the violations listed in subsection (A) in precisely the words used in that subsection, the member state shall construe the descriptions to apply to offenses of the member state that are substantially similar to the ones described. A state that is a member of the Drivers License Compact shall report to another member state of the compact a conviction for any other offense or any other information concerning convictions that the member states agree to report. (C) For a conviction required to be reported under subsection (A), a member state shall give the same effect to the report as if the conviction had occurred in that state. For a conviction that is not required to be reported under subsection (A), the provisions of Section 56-1-320 shall govern the effect of the reported conviction in this State. For a conviction that is not required to be reported under subsection (A), notice of the conviction must be received by the Department of Motor Vehicles for purposes of suspension or revocation within one year of the date of conviction. The department shall not post to an individual's driver's record any conviction that is not received by the department within the one-year period for offenses governed by this subsection. For purposes of this title, this means all convictions which occurred after June 4, 1995, which are not required to be reported pursuant to subsection (A). The department may not refuse to issue or renew a resident's driver's license when the individual's privilege to drive is suspended or revoked for an out-of-state conviction which was not reported to the department within one year of the date of conviction, as required in this subsection.
