Ignition interlock device requirements
- First DUI offense: Installation of interlock device for six months to one year upon 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 restoration
- Third DUI offense: Mandatory installation of interlock device during license suspension and for 1 to 3 years following restoration
