Ignition Interlock Device (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.

Subsequent offenses have longer IID restriction requirement time frames.

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 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.
