If you are arrested and convicted of a DUI in Arizona, you may be subject to new ignition interlock device laws. These Arizona DUI laws determine that you cannot be trusted to operate a motor vehicle without some sort of assurance that you are sober. A device is attached to your automobile (at your expense) that will test you for alcohol before you can start the ignition. If the device detects alcohol in your system, the car will not start and you will not be able to operate it until you are sober. This device is believed to prevent accidents due to drunk driving.

What is an Ignition Interlock Device?

The ignition interlock device is a cell phone sized device that is connected to your car's ignition system. Before you may start the ignition, you are required to give a breath sample. If any alcohol is detected, the ignition will not start. If you are alcohol free, you may start the car. You will then be asked to periodically breathe into the machine to ensure that you are sober enough to drive, to ensure that you're not drinking as you drive.

The ignition interlock device laws in Arizona are based on the report by the International Council on Alcohol, Drugs and Public Safety that says that the devices, when combined with a monitoring and service program, have resulted in a forty to ninety percent decrease in repeat DUI offenders as long as the device remains on the automobile.

Who Receives the Ignition Interlock Device?

You may be required to install an ignition interlock device after a second DUI offense in Arizona.

If the Arizona ignition interlock device law mandates that you are eligible to receive the device following license suspension or revocation, you must first complete the ninety day revocation period.  You must also contact MVD to verify eligibility, and you must not have any other motor vehicle offenses or outstanding withdrawal actions on your driving record.  You must have the certified ignition interlock device (CIID) installed on your vehicle and then provide proof of the installation to MVD with a "proof of installation" form; you must complete any required rehabilitation programs; and you must pay all the required fees, as well as submit proof of future financial responsibilities.

Special Ignition Interlock Restricted Driver's License (SIIRD)

After completing all the requirements, you will be issued a Special Ignition Interlock Restricted Driver's License (SIIRD), which will contain the words "Ignition Interlock" so that law enforcement officers will know that your car is equipped with such a device if you are ever pulled over. This restricted driver's license is only valid during the suspension period and can be used to travel to and from certain locations.

Ignition Interlock Driving Restrictions

The ignition interlock device law in Arizona states that, while you have the SIIRD license, you may only drive to and from your place of employment and residence during specified times. You may also drive to and from any educational facility according to your educational schedule. You may drive to and from any rehabilitation programs and/or treatment facilities while you have the restricted license and you may also travel to and from any doctor's office or any ignition interlock service facilities.

Certified Ignition Interlock Device Installers

Your certified ignition interlock device may only be installed by a certified installer. You can get a list of certified installers from MVD. Also, your IID must be calibrated every thirty days for the first three months that it's installed on your automobile, and then every other month until the duration of your installation requirement. 

If you are facing a second DUI offense in Arizona, an ignition interlock device is a likely possibility. Contact Hock Law Group for more information about ignition interlock device laws in Arizona and a free initial consultation on your case.
