Ignition Interlock Devices

In Arizona, a DUI conviction results in you having to use an Ignition Interlock Device (IID) on all of your personal vehicles for a certain period of time.  An IID is a device that connects to the ignition and power system of a vehicle and is designed to prevent the vehicle from being started if the driver’s alcohol level is above a certain level.

How Ignition Interlock Devices Work

After a driver turns on the power of the vehicle, the IID unit will give a warning instructing him to blow into the IID sensor.  The device then analyzes the driver’s BAC, and if the results are below a 0.03, they are allowed to start the vehicle.  If the driver registers above the maximum level,  the IID locks him out and will not allow the car to be started.  When the driver is back below the maximum level, he can then start the vehicle.

Whenever the car is started, the IID records all the information so it can be sent to Arizona Motor Vehicle Division.  It will automatically record the date, time, test result, and BAC.  Of course, if the driver makes any attempts to circumvent the system or otherwise tamper with it, that information is recorded as well.  This information is sent to MVD, and if negative information is reported, you may end up having to keep the IID on your vehicle beyond the normal time-frame.

Once the vehicle is started, the IID will require the driver to provide breath samples at random times while driving.  This was implemented as people were having their friends blow into the device in order to start the car, and then driving themselves.

What is the Cost?

There are various companies that provide the IID devices, and they are all listed on the Arizona MVD website.  The installation fees vary, and some companies have no installation fee at all.  The monthly fee is usually around $75.00 per month.  All of these fees are the responsibility of the driver and are mandatory upon a conviction in Arizona.

What Are the Service Requirements?

The Arizona IID program requires that you bring the IID in for routine inspection monthly for  the first three months, and then every 60 days after that.  You also need to bring the device in for inspection anytime it registers a BAC over 0.03.  If you fail to bring in the device for service when you are required to do so, the IID will shut down your car, and you will not be allowed to start the vehicle until the unit is serviced.
