Ignition Interlock Device Requirements in Arizona

What is it?


An Ignition Interlock Device (an I.I.D.) is a device that is connected to your car’s ignition and installed on your car’s dashboard. It analyzes your breath before it allows you to start your car. Basically, it means that, before you start your car, you have to blow into it. If the IID detects alcohol on your breath, it won’t let you start your car.


Even after you’ve started your car, the IID will randomly require you to provide another breath sample. If you don’t breathe into the IID, or, if the IID detects alcohol on your breath, it will record this as a violation, warn you, and then initiate an alarm until you turn off your car or provide a sufficient breath sample.


Of course, the car will not automatically stop once started for safety reasons.


How much does it cost?


An IID will end up costing you around $1,000 annually after installation and monthly rental fee. Some companies charge a bit less, and others charge a bit more. Some companies charge per violation your IID records. Some companies even charge a removal fee. Either way, you must rent your IID from an Arizona Motor Vehicle Division (AZMVD) approved company.


Will I have to have an one installed, even if this is my first DUI conviction?



I know.


Unfortunately, with Arizona’s harsh stance on DUI convictions, even though a DUI conviction may be your first, you will still be required to install an IID in their cars.


Upon receiving your DUI conviction, and once your driving privileges have been restored, the state will issue to you what is called a Special Ignition Interlock Restricted Driver’s License (“SIIRDL”) under A.R.S. §28-1401.


While you have a SIIRDL, you will generally be restricted to driving only to and from work, school, approved medical appointments, probation proceedings, alcohol/drug counseling, and to IID calibration appointments.
