  • Standard DUI (first or second offense) - Interlock device required for 12 months
  • Extreme DUI (first or second offense) - Interlock device required for 12 months
  • Super extreme DUI (first offense) - Interlock device required for 18 months
  • Super extreme DUI (second offense) - Interlock device required for 24 months
  • Aggravated DUI - Interlock device required for 24 months
How Does the Interlock Device Work?

An ignition interlock device is a tool that measures the blood alcohol content (BAC) of an individual. If you are required to use an interlock device, you will need to arrange for installation through an MVD-authorized company and provide proof of installation to MVD. The device is placed inside the vehicle of a person who has been convicted of DUI as a safety measure. The device requires the person to blow into it to register their BAC before they can start the engine of their vehicle. If the device records a person's BAC as being over the legal limit (in this case, 0.08%), then it will prevent the vehicle from starting. This renders the person unable to drive while under the influence. If no alcohol is detected, the engine will start and once started, the device will require another breath sample at random intervals while you are driving as well. MVD monitors the interlock device and receives periodic usage reports from the interlock installer, including any violations or device tampering. If they determine there has been a failure to comply with the interlock requirements, the length of time for your interlock requirement can be extended.
