Modifies provisions relating to ignition interlock device requirements for certain intoxication-related traffic offenses

HB 645 modifies license suspension rules for drivers convicted of certain traffic offenses involving intoxication. It allows drivers to avoid a 30-day license suspension if they install and maintain a functioning ignition interlock device (IID) in their vehicle, instead requiring a 90-day restricted driving period. The bill mandates proof of IID installation to prevent suspension, with failure to maintain the device or file required documentation leading to extended restrictions or resuspension. This directly affects drivers with DUI-related convictions who would otherwise face license penalties under existing point systems.
