License Reinstatement

South Carolina now requires Ignition Interlock Devices for all drivers with an arrest date after May 19, 2024 who want to continue to maintain driving privileges after a DUI. Here’s how it works, according to the South Carolina Department of Probation, Parole, and Pardon Services:

  1. You’ll receive a letter from the state notifying you of eligibility for the Interlock Device program. Note that you’ll have to complete the Alcohol and Drug Safety Action Program (ADSAP) before having your device installed.
  2. Have your Interlock Device (called a Breath Alcohol Ignition Interlock Device, or BAIID, in South Carolina) installed at a service center by a state-approved provider like Smart Start. Be aware that you’ll have to have the BAIID serviced at least once every 60 days.
  3. Obtain an installation certificate for your BAIID. Bring the certificate to a South Carolina DMV office, present it, and apply for an Ignition Interlock Restricted License. You may not drive to the DMV office yourself, and you’ll only be allowed to drive vehicles equipped with a BAIID while the restriction is in place. 

Getting your South Carolina driver’s license back requires following steps specific to your DUI program. Contact the SCDMV at 803-896-5000 to determine your eligibility for reinstatement, and keep the SCDMV’s links handy to pay your reinstatement fees and verify your eligibility for a payment plan.
