What Is an Extreme DUI Under Arizona Law?
Under ARS 28-1382(A)(1), a driver commits an Extreme DUI when their blood alcohol concentration (BAC) is 0.15 or higher but below 0.20 within two hours of driving or being in actual physical control of a vehicle. Actual physical control concerns whether the person could operate the vehicle under the surrounding circumstances. The Extreme DUI threshold is nearly double Arizona’s standard DUI limit of 0.08 under ARS 28-1381.
Arizona recognizes three BAC tiers. A standard DUI begins at 0.08, the Extreme tier begins at the threshold above, and ARS 28-1382(A)(2) applies at 0.20 or higher. These offenses are Class 1 misdemeanors. Separate circumstances can lead to Aggravated DUI, which is a felony charge.
The two-hour measurement period is part of what the State must prove. The prosecution must connect a qualifying test result to the relevant conduct during that period, not merely show that a later test exceeded the threshold.
Mandatory Penalties for an Extreme DUI Conviction
ARS 28-1382 establishes mandatory minimum jail terms for Extreme DUI convictions. The applicable sentence depends in part on the BAC tier and whether the person has a qualifying prior DUI violation within 84 months.
Consequences addressed by the Extreme DUI statutes include:
- First Extreme DUI: A first conviction involving a BAC of at least 0.15 but below 0.20 requires at least 30 straight days in jail.
- Ignition interlock reduction: A judge may suspend all but nine jail days if the person equips a vehicle for 12 months with a certified ignition interlock device, a breath-testing unit connected to the vehicle.
- Repeat Extreme DUI: A second violation involving a BAC below 0.20 within 84 months carries at least 120 days in jail, including 60 consecutive days.
- Administrative suspension: A license suspension imposed by ARS 28-1385 lasts at least 90 days and proceeds separately from criminal sentencing.
These are statutory minimums. The full criminal sentence depends on the charged BAC tier, prior record, and other facts established in the case.
Super Extreme DUI Penalties in Arizona
Super Extreme DUI is a separate BAC-based charge defined by ARS 28-1382(A)(2). It applies when the State alleges a BAC of 0.20 or higher within two hours after driving or controlling a vehicle.
Its distinct statutory requirements include:
- First offense: A first Super Extreme DUI conviction requires at least 45 straight days in jail and carries a minimum fine of $500.
- Interlock reduction: A judge may suspend all but 14 jail days if the person equips a vehicle with a certified interlock device for 12 months.
- Second violation: A second violation within 84 months requires at least 180 days in jail, including 90 consecutive days.
The difference between a test result below 0.20 and one at or above 0.20 directly affects the mandatory minimum sentence. That makes the accuracy, timing, and handling of BAC evidence central to the defense analysis.
Defense Strategies in Extreme DUI Cases
An Extreme DUI prosecution depends heavily on BAC evidence and its connection to the operation or control of a vehicle. We examine whether the State can prove every required element, including the legality of the stop and the reliability of the testing process. The available challenges depend on the evidence in the individual case.
Rising BAC
If alcohol was consumed shortly before driving, the BAC could have been below 0.15 while the person was driving and risen before testing. The timing of consumption, driving, and testing must be examined against the State’s two-hour burden.
Breath Test Records
Breath test evidence can be reviewed for calibration and maintenance records, test administration, and compliance with required procedures. A reading near a statutory threshold deserves particular scrutiny because the charged BAC tier changes the mandatory minimum sentence.
Blood Draw Evidence
We examine whether the blood draw was legal and review the chain of custody, sample handling, and laboratory methodology. The analysis can include whether the tested sample is reliably connected to the person and the reported result.
The Two-Hour Window
The State must prove that the charged alcohol concentration existed within two hours after the person drove or controlled the vehicle. Delays between driving, the stop, the blood draw, and laboratory testing are part of that analysis.
Actual Physical Control
When the person wasn’t actively driving, the surrounding circumstances become important. The vehicle’s location, access to the keys, and whether the engine was running can be disputed based on the evidence.
Traffic Stop & Evidence Collection
The legality of the initial stop and the collection of evidence afterward can be challenged when the facts support it. We review police reports and body camera footage, along with field sobriety testing and the procedures used to obtain breath or blood evidence.

How Extreme DUI Cases Move Through Scottsdale’s Courts
Non-aggravated misdemeanor Extreme DUI cases arising in Scottsdale fall within Scottsdale City Court jurisdiction. Felony-level charges proceed in Maricopa County Superior Court. The exact court track depends on the offenses filed, not solely on the BAC allegation.
The criminal case begins with an arraignment, where the charges are formally presented and a plea is entered. Later stages can include disclosure of the State’s evidence, motions addressing contested evidence, negotiations, and trial preparation.
The MVD administrative matter proceeds on a separate track and addresses driving privileges rather than guilt on the criminal charge. Action in one proceeding doesn’t automatically resolve the other, so we address the court case and the administrative license issue as distinct matters from the beginning.
