If you were charged criminally with impaired driving, driving with a blood alcohol level over the legal limit or failing or refusing to provide a breath sample, and you plead guilty or are found guilty after trial, you may be able to access Ignition Interlock almost immediately. Check with your lawyer to find out more about your options.
If you only received the Notice of Administrative Penalty (also known as the Immediate Roadside Sanction) under the SafeRoads regime, and you either do not fight it or are unsuccessful on your review in front of the SafeRoads Adjudicator, you will have to wait until 60 days after the Notice was issued before you can apply for admission into the Ignition Interlock program. You cannot actually operate a vehicle with Ignition Interlock until 90 days after the date of the issuance of the NAP.
