General Information

Ignition Interlock Program

What is an “Interlock?” An Ignition Interlock is a device that is installed on motor vehicles to prohibit individuals from operating a vehicle while under the influence of alcohol. It requires your breath sample before the engine will start and you are periodically required to provide breath samples while driving. If the device detects an elevated alcohol concentration level, the vehicle will not start.

You will be required to have an Ignition Interlock Device and make application for an Ignition Interlock Restricted License if you have been convicted of Driving under the Influence of Alcohol.

  • 1st DUI conviction with a BAC of .15 or above
  • 2nd or subsequent DUI conviction regardless of the BAC level

Circumventing or disconnecting the device will result in additional legal action, driving penalties and additional ignition interlock required time. Anyone assisting with device tampering and/or circumvention may also be subject to criminal and/or suspension action.

Ignition Interlock Restricted License

Once you have received notification from the Department of an ingnition interlock requirement, you will need to do the following:

  • Have a Wyoming approved ignition interlock device installed in any vehicle you plan on driving. The device must be installed in Wyoming at an approved Sevice Center by a Wyoming Certified technician. The driver must provide a copy of the ignition interlock device installation certificate to the Department;
  • File SR-22 insurance with the Department;
  • Apply for a special “IIR” restricted driver’s license.
  • Pay the $50 reinstatement fee, regular driver license fee and the $100 ignition interlock administrative fee.
