IID without regisetered vehicle

[Leslie Fisher]

What is the name of your state (only U.S. law)? Arizona
I am looking at being convicted for a first time DUI. Arizona requires you to get a IID installed in your vehicle for one year upon conviction. I do not have a vehicle and was driving someone elses vehicle upon the time of the offense. So what happens? Do I not have to get one?, does one have to go into the vehicle I was driving at the time of the offense? PLease Help with any info you may have

Your license is essentially restricted so that you must be driving a car with an interlock.
The interlock must be installed in whatever vehicle you intend to drive. Doesn't matter what you were driving at the time of your arrest.
