In the state of Michigan, a driver who commits a DUI offence has their license mandatorily suspended for a period of 6 months. The suspension period could be in excess of that if the offender registered a BAC of .17 or greater. It is, however, possible to have your driving privileges reinstated if you appeal to the Driver Appeal and Assessment Division. If your appeal is successful, you may be required to have an ignition interlock device installed in your motor vehicles. The installation of such a device may be mandatory in cases where a driver registers a BAC of .17 or higher.

In the case of repeat offenders, a driver’s license will be revoked. Once the revocation period has expired, such an offender can apply for a restricted license, which will require the installation of an ignition interlock device. The interlock device must be installed for a period of 1 year or longer, and it must be monitored monthly, If the offender drives for work, their employer will be notified of this requirement, but will not be required to install an ignition interlock device on the work vehicles. Failing to meet the requirements of the ignition interlock program may result in your license plates being confiscated or your vehicle being impounded or immobilized.
