Ignition Interlock Restriction Information (IID)

Any person convicted of a DUI alcohol violation will be ignition interlock restricted. If you are under 21 at the time of arrest, it is for three (3) years; if 21 and older, it is for 18 months.

A breath alcohol ignition interlock device (IID) is a constant monitoring device that, when installed in a motor vehicle, prevents the motor vehicle from being started without first sampling the operator’s breath alcohol concentration. If the operator’s breath alcohol concentration is greater than a predetermined concentration level, the device prevents the motor vehicle from being started.

When a driver is ignition interlock restricted, they must not drive any vehicle, including motorcycles, without an ignition interlock device installed.

The driver license record is updated to show the ignition interlock restriction, and the driver is notified by mail of the restriction.  Law enforcement has access to see the ignition interlock restriction and will issue a citation when they make contact with a driver who is driving a vehicle without an ignition interlock device installed.

Effective March 12, 2024, Utah Administrative Rule R708-31 for the Ignition Interlock program, requires all Ignition Interlock restricted drivers to have a camera installed into their vehicle with their current ignition interlock device.  All restricted drivers will need to have this completed by October 31, 2024 to maintain compliance with the updated rules. Please contact your provider for further information.

IID Suspension Times

If convicted for operating or being in actual physical control of a motor vehicle in Utah without an ignition interlock device, your driving privilege will be revoked for a period of one (1) year from the conviction date.  An ignition interlock device suspension may be cleared by one (1) of the following:

  • Payment of reinstatement fee and receipt of electronic notification from an ignition interlock system provider showing proof of the installation of an ignition interlock system on your vehicle or the vehicle you will be operating.
  • Payment of a reinstatement fee and, if you do not own a vehicle or will not be operating a vehicle owned by another individual, electronic verification that you do not have a vehicle registered in your name in Utah and receipt of employer verification.
  • Payment of a reinstatement fee and, if you are not a resident of Utah, verify you do not own a vehicle in Utah by electronic verification that you are licensed in another state of residence, or you are in the process of obtaining a license in your state of residence.

If the IID is removed prior to the ending date of the ignition interlock restriction period, the license will be re-suspended until an IID is installed and an additional reinstatement fee is paid.

Effective May 3, 2023, upon receipt by the division of any notice of a breath violation or failure to calibrate/monitor the ignition device, results in a 60-day extension to the ignition interlock restricted driver for each violation.
