Illinois Ignition Interlock DUI Laws

Interlock Process

If this is your 2nd or higher offense in Illinois, you will be applying for a Restricted Driving Permit (RDP). Multiple DUI arrests will require either a formal or informal hearing. Informal hearings will be at regional Drivers Services facilities. Formal hearings are requested in writing with a $50 filing fee.

How do I get an Illinois Restricted Driving Permit with an Ignition Interlock?

  • If your license was suspended as a result of a conviction, you must apply for a restricted driving permit at the IL court in which you were convicted.

  • Complete any alcohol/drug education and/or treatment programs as ordered by the court.

  • Call LifeSafer Ignition Interlock at 800-634-3077 to schedule your ignition interlock installation. Ask about money-saving offers and discounts!
