Ignition Interlock in Phoenix, Arizona
If a Maricopa County court or the Arizona MVD has ordered an ignition interlock, you are looking at a certified device for 12 to 24 months depending on your charge. Arizona runs interlock as a single statewide program — the rules in downtown Phoenix are the same as everywhere else in the state. What changes outcomes is who sets it up and who watches your logs.
Phoenix cases, statewide rules
Whether your DUI ran through the Phoenix Municipal Court, a Maricopa County justice court, or Superior Court, the interlock order traces back to the same Arizona statutes — it is not a Phoenix-specific rule that a local installer can interpret for you. A device company in the Valley will mount the unit and collect the monthly lease. It will not read your data for false readings, and it will not stand between you and a violation that could extend your term. That gap is exactly what AES fills.

The four things every Phoenix interlock client asks about — answered for the whole state, because the program is uniform.
How long is my term?
12, 18, or 24+ months depending on whether your Maricopa County case was a first offense, an extreme DUI, or an aggravated charge — and when the clock actually starts.
Check the termWhat does it cost?
Install, the monthly lease, the calibration visits, removal — plus the violation fees and lockout charges that quietly add up if no one is watching your logs.

Mouthwash, breath chemistry, and a cold start can all read as a positive. There is a short window to dispute it — and AES, not the installer, is who pushes back.
Protect yourselfWhen can I take it off?
Removal is not automatic at the calendar mark. A clean compliance record near the end of the term is what gets the device off — and one late violation can reset it.

AES coordinates your install with a certified Arizona partner, handles the required screening, and monitors your interlock logs so a false violation does not quietly add months to your term. The device company answers to itself. AES answers to you.
