Enrollment in the Ignition Interlock Device Program is mandatory after your _______ DWI conviction.
Enrollment in the Ignition Interlock Device Program is mandatory after your third DWI conviction. An ignition interlock device will be installed on your vehicle. The ignition interlock device will prevent your vehicle from starting if it detects that your blood alcohol concentration (BAC) is 0.02% or above. (An average 180-pound man will reach a BAC of 0.03% by consuming one shot of 80-proof liquor, one 12-ounce can of beer, or five ounces of wine before his body starts to break down the alcohol.)
