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. That threshold is nearly double Arizona’s standard DUI limit of 0.08 under ARS 28-1381.
Arizona recognizes three tiers of impaired driving by BAC. A standard DUI begins at 0.08. An Extreme DUI begins at 0.15. A Super Extreme DUI under ARS 28-1382(A)(2) applies at 0.20 or above and carries even steeper mandatory minimums. All three are Class 1 misdemeanors, the most serious misdemeanor classification in Arizona, though an Extreme DUI can escalate to Aggravated DUI, a felony, under certain conditions.
Aggravation factors that can elevate the charge include a suspended, canceled, revoked, or refused license at the time of arrest; two or more prior DUI convictions within 84 months; driving the wrong way on a controlled-access highway; or having a passenger under 15 in the vehicle. Arizona’s actual physical control standard also means a driver can face a charge in a parked vehicle if the circumstances suggest the vehicle posed a safety risk.
Mandatory Penalties for an Extreme DUI Conviction
The penalties for a first-offense Extreme DUI conviction are mandatory minimums, not judicial suggestions. A sentencing judge has limited room to reduce them.
First-offense minimums under ARS 28-1382(D) include:
- Jail: 30 consecutive days. Under ARS 28-1382(I), a judge may suspend all but 9 days if the defendant installs a certified ignition interlock device (IID) for 12 months, but this reduction is discretionary.
- Fines and surcharges: Approximately $2,500 to $3,000 or more in total
- License suspension: 90 days
- Driving record: 8 points added
- Mandatory alcohol screening, treatment, and Traffic Survival School
- Vehicle impoundment: 30 days may apply immediately upon arrest
A second Extreme DUI, or any Extreme DUI where the driver had a prior DUI conviction of any type within 84 months, carries a mandatory minimum of 120 days in jail, at least 60 served consecutively, a one-year license revocation, and fines and assessments generally starting around $3,250 or more. A third DUI within 84 months, regardless of BAC, may be charged as a Class 4 felony carrying a minimum of four months in state prison.
Collateral consequences extend well beyond the sentence. SR-22 insurance filings are required for at least three years, and premiums increase substantially. A conviction may affect professional licenses in law, medicine, real estate, and other regulated fields. The criminal record is permanent.
Defense Strategies in Extreme DUI Cases
An Extreme DUI charge is built on BAC evidence. That evidence isn’t immune to challenge. Depending on the facts of the case, several defense approaches may be available.
Rising BAC Defense
If alcohol was consumed shortly before driving, BAC may have still been below 0.15 while the driver was behind the wheel but risen above that threshold by the time of testing. A toxicology expert can calculate the estimated BAC at the actual time of driving, which may undercut the prosecution’s core evidence.
Breath Test Calibration and Margin of Error
Arizona breath test equipment carries a margin of error. A reading at or near the 0.15 threshold may be challengeable on calibration, maintenance records, and test administration.
Blood Draw Challenges
Blood draw evidence can be examined for warrant validity, the qualifications of the person who performed the draw, chain of custody, and laboratory testing methodology. Procedural failures at any stage may affect the admissibility or reliability of the result.
The Two-Hour Window
The state must prove the BAC was 0.15 or higher within two hours of driving. Delays between the traffic stop and the test create a factual window for challenge.
Actual Physical Control Disputes
When the driver wasn’t actively operating the vehicle, the prosecution must prove actual physical control. Relevant factors include whether the ignition was on, where the keys were located, and whether the vehicle posed a safety risk. These are contestable facts.
Constitutional Challenges
The lawfulness of the initial stop, proper administration of field sobriety tests, and whether the implied consent advisory was correctly delivered can all be examined. Body camera footage and inconsistencies in the police report may support suppression motions or raise reasonable doubt at trial.
How Extreme DUI Cases Move Through Scottsdale’s Courts
Misdemeanor Extreme DUI cases in Scottsdale are typically heard in Scottsdale City Court when the arrest is made by Scottsdale Police. Arrests by Arizona DPS or county officers may result in filing in a Maricopa County Justice Court serving the area, such as Desert Ridge, McDowell Mountain, or West Mesa Justice Courts.
Two proceedings run concurrently after an arrest. In the criminal case, the first appearance is an arraignment where the charges are formally presented and a plea is entered. In the MVD administrative process, the arresting officer typically issues a 15-day temporary driving permit. After that window closes, the administrative license suspension begins unless a hearing has been requested within 15 days of arrest. Retaining an attorney before arraignment allows both tracks to be addressed from the start.
