How the Program Works in South Carolina

The DMV requires an interlock on any vehicle the person drives (except a moped or motorcycle) after a DUI, DUAC, felony DUI or child-endangerment conviction. For an implied-consent or 0.15 suspension, the interlock runs for the time remaining on the suspension, at least 3 months. The program is run by the Department of Probation, Parole and Pardon Services, which uses a point system that can extend the interlock period or suspend the restricted license. The driver pays for the device; indigent drivers may apply for help from the Ignition Interlock Device Fund.
