LifeSafer Ignition Interlock

South Carolina

How do I get an interlock license?

South Carolina’s Interlock Program is managed by the State’s Department of Probation, Parole, and Pardon. The Ignition Interlock Device (IID) Program receives a list of offenders from SCDMV who are qualified for the program. If you become eligible for the IIDP, you will be notified by the IIDP system letter that you are now eligible and may participate in the IIDP. Offenders become eligible once they have satisfied any required suspension period associated with their conviction.

This occurs when you are sentenced by a court after a trial or plea agreement.

When you are arrested for a DUI in South Carolina, the officer on the scene will issue you a temporary license which allows you to drive for 10 days in order to get your affairs in order. You can challenge your case during this time. If you do not, or if your challenge is unsuccessful, your license will be suspended on the 11th day for six months. After your suspension, you will receive a restricted license, which will allow you to drive to certain approved locations.

Ignition interlock devices are mandatory for all drivers convicted of SC DUI offenses. You may also be able to install an ignition interlock device in lieu of administrative suspension. An alcohol and drug safety action program is mandatory after a DUI conviction.

In South Carolina, the severity of your judicial sentence depends on your blood alcohol concentration (BAC) at the time of the arrest and the state has three BAC measurements. Like most states, it is against the law to drive with a BAC level over .08. If your BAC level is between .10 and .16, your penalties are more severe, and a BAC of .16 or higher results in the strictest penalties. A 4th DUI offense is a felony in South Carolina.
