If your drivers license was suspended for a DUI (Driving Under the Influence) offense, the court may require you to get an ignition interlock device to prevent a vehicle from starting if your BAC exceeds 0.05%.
Ignition Interlock Device Requirements
- First DUI offense: Installation of interlock device for six months to one year upon drivers license restoration (judge’s discretion); BAC 0.15% or greater requires mandatory installation of ignition interlock device during license suspension and for 6 months to 1 year following restoration
- Second DUI offense: Mandatory installation of interlock device during license suspension and for 1 to 3 years following drivers license restoration
If the court sentences you to get an interlock device, you will receive a notice of suspension from MVC with instructions on how to obtain the device. Failure to have an ignition interlock installed when ordered by a judge could result in an additional one year driving privilege suspension.
