Ignition Interlock Device Program

An ignition interlock device (IID) is a breath alcohol analyzer connected to the ignition system of a vehicle. The driver must blow into the device, and if his or her breath alcohol level exceeds the accepted level set on the device, the vehicle will not start. In addition, at different times while driving, the driver will be prompted to blow into the device to ensure he or she is not under the influence.

The IID Program allows DC DMV to reduce the license revocation periods for first or subsequent alcohol-related offenses. If you participate in the IID Program, you can get a restricted DC DMV driver license (either a restricted REAL ID license or a restricted Limited Purpose license) and drive designated vehicles with installed IIDs. If you have a commercial driver license (CDL), you are not eligible to participate in the Ignition Interlock Device Program.

The restriction and conditions on your driver license and on your driving will remain in place for the period in which your driver license has been revoked. That period of time will be extended if you violate the IID Program rules or commit another driving-related violation.

General Information

If you would like to participate in the IID Program, you must fill out an Ignition Interlock Device Application, obtain High Risk (SR22) Insurance, and meet the eligibility requirements.

Eligibility (Current DC license holders)

To be considered for this program, you must:

  • Have held a DC DMV driver license immediately prior to revocation.
  • Has either been convicted in court of an alcohol-related offense or had your license revoked administratively because of an alcohol-related offense.
  • Not have any additional or pending license suspensions or revocations.
  • Have not been convicted of causing injury or death while operating a motor vehicle in any jurisdiction.
  • Have enrolled or completed a District of Columbia Department of Behavioral Health (DBH) approved substance abuse treatment program.
  • Have not previously unsuccessfully participated in this program or any similar program in another jurisdiction for 5 years prior to the date of the application.
  • Complete and submit the DC DMV Ignition Interlock Program Application and pay the associated DMV fees.
  • Obtain and maintain High Risk SR22 Insurance.
  • Meet any other criteria as required by the Director of the DMV.

Eligibility (New Resident converting out-of-state IID license)

If you are an out-of-state driver with an IID restriction who wishes to convert an out-of-state restricted IID license to a DC DMV IID restricted license, you must:

  • Meet the requirements to convert your license to a DC license.
  • Be currently enrolled (minimum of 30 days) in another state/jurisdiction’s certified IID program and have at least one vehicle with an installed IID for a minimum of 30 days before date of application.
  • Currently possess a valid out-of-state driver license with IID restriction (minimum of 30 days).
  • Provide a certified driving record (issued within the last 30 days) from the licensing jurisdiction.
  • Provide the vehicle registration and IID monthly reports reflecting activity and triggered events (30 days minimum reporting requirement).
  • Provide proof of substance abuse treatment enrollment or completion from the jurisdiction in which the infraction occurred.
  • Visit and obtain an IID from a DC DMV approved IID provider within 30 days of enrollment into the IID program. Vehicle must be registered in DC prior to visiting the IID approved provider.
  • Remain in the IID program for the duration of either (1) the original IID license restriction in the previous jurisdiction or (2) the IID license restriction that the driver would have received if the infraction occurred in the District of Columbia, whichever duration is longer. Once enrolled in the DC DMV IID Program, you will be required to follow the DC DMV requirements for the IID Program and may also be required to continue compliance with the requirements from the court or jurisdiction that initially required or allowed the installation of the IID.
  • Have not been convicted for causing injury or death while operating a motor vehicle in any jurisdiction.
  • Obtain and maintain High Risk SR22 Insurance.
  • Obtain a DC DMV driver license.
  • Title and register your vehicle in the District of Columbia.
  • Meet any other criteria as required by the Director of the DMV.
