Maryland Ignition Interlock DUI Laws

Interlock Process

At the time of your arrest, you will receive a paper license (DR15A) valid for 30 days. The DR15A allows you to drive only within this time period, so make sure to act quickly.

How do I get an interlock license?

  • Your paper license comes with instructions on how to regain driving privileges by obtaining a interlock restricted license or requesting a MVA hearing.

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

  • Have your interlock installed. You will receive proof of installation and a lease agreement.

  • Take your proof of installation to a Motor Vehicle Administration (MVA) office to obtain your restricted license.
