Am I Required to Have an Interlock Device?

(Last Updated On: October 30, 2018)

Arizona Interlock Device

When a person is convicted of regular misdemeanor DUI, extreme DUI, super extreme DUI or aggravated DUI, the law requires the installation of an interlock device on any vehicle to be operated by that person.

An interlock device connects a Breathalyzer to the vehicle?s ignition system.

The device will prevent the vehicle from starting unless the driver blows into the device and the person’s alcohol concentration is below a preset level.

The costs for installation and maintenance shall be paid by the driver, and the court may order it to be used from one to three years.

The driver will also be required to show proof of compliance and proof of inspection for accuracy at least once each calendar year.

Failure to provide compliance and calibration records may require the driver to maintain the interlock device for an additional year.
