Understanding Arizona’s Super Extreme DUI — Charges, Penalties & Court Paths in Maricopa County
A super extreme DUI in Arizona is a Class 1 misdemeanor under ARS § 28-1382(A)(2) for driving with a 0.20+ BAC within two hours of driving or being in actual physical control. It carries mandatory jail (45 consecutive days, reducible to 14 with IID per § 28-1382(I)), substantial fines, a 90‑day MVD suspension, and 12‑month ignition interlock.
What Arizona calls a “super extreme DUI”
Arizona’s “super extreme DUI” applies when the State proves your blood alcohol concentration was 0.20 or higher within two hours of driving or being in actual physical control. The statute is ARS § 28-1382(A)(2). This is still a misdemeanor (Class 1) unless aggravating factors under ARS § 28-1383 elevate it to a felony.
Two-hour window evidence matters. Prosecutors must link the test result back to the time of driving. That often requires retrograde extrapolation and expert testimony. Challenges can focus on timing, the quality of the blood or breath test, and whether you were in “actual physical control” at all, an element Arizona courts treat fact‑specifically based on the totality of circumstances.
Because Arizona mandates jail for super extreme DUI, defense work concentrates on attacking BAC reliability, limiting admissibility, negotiating charge reductions (to extreme under § 28‑1382(A)(1) or to impaired under § 28‑1381(A)(1)/(A)(2)), and structuring sentences to reduce days in custody via ignition interlock eligibility or a court‑authorized home detention program where available.
Penalties & collateral impact
For a first‑time super extreme DUI, ARS § 28‑1382 imposes at least 45 consecutive days in jail. If you equip an ignition interlock device (IID) as ordered, the court may suspend all but 14 days of jail under § 28‑1382(I). Fines, assessments, and surcharges add up to several thousand dollars, plus jail costs and IID fees.
Driving consequences flow through the Arizona Department of Transportation (ADOT) and MVD. A test over the legal limit triggers an administrative per se suspension under ARS § 28‑1385: 90 days (with eligibility for a restricted permit after 30 days in many cases). A refusal under ARS § 28‑1321 causes a 12‑month (or 24‑month for a prior) suspension. For super extreme convictions, MVD requires at least 12 months of IID under ARS § 28‑3319.
Collateral effects include higher insurance (SR‑22 filings), employment issues for commercial drivers (CDL disqualification under federal and state rules), and immigration or professional licensing considerations. Courts may order alcohol screening, classes, community restitution, and compliance monitoring. Some city and county courts authorize home detention or continuous alcohol monitoring under ARS §§ 9‑499.07 and 11‑251.15 after a portion of jail is served; availability and terms vary by court and offense history.
Local courts & case flow
Most super extreme DUI cases in the Phoenix metro are filed in limited‑jurisdiction courts: Phoenix Municipal Court, Scottsdale City Court, Tempe Municipal Court, or a Maricopa County Justice Court, depending on where the stop occurred. If the case is aggravated under ARS § 28‑1383 (e.g., suspended license, third within 84 months, or a child under 15 in the vehicle), it is a felony handled in Maricopa County Superior Court.
The typical misdemeanor timeline includes arraignment, pretrial conferences, motion practice (e.g., suppression of blood results for a defective warrant, or exclusion for calibration noncompliance), settlement conferences, and trial. Arizona Rule of Criminal Procedure 8 sets speedy‑trial limits; Rule 15 governs discovery; Rule 16 covers pretrial motions and evidentiary hearings. Outcomes vary—from dismissals and not‑guilty verdicts to pleas that reduce jail exposure or charges.
Blood‑draw evidence is frequently litigated. The Arizona Supreme Court in State v. Valenzuela, 239 Ariz. 299 (2016), applying Missouri v. McNeely, 569 U.S. 141 (2013), held that implied consent does not substitute for a warrant or voluntary consent. If the State cannot prove a valid warrant, exigency, or voluntary consent, blood‑test evidence may be suppressed. Breath testing requires foundational proof of proper instrument certification, operator permits, and calibration records.
Arizona statutes, penalties & procedure
Core DUI statutes
• ARS § 28‑1381(A)(1) & (A)(2): Impaired to the slightest degree, or 0.08+ BAC. Class 1 misdemeanor.
• ARS § 28‑1382(A)(1) & (A)(2): Extreme (0.15–0.199) and super extreme (0.20+). Class 1 misdemeanors with enhanced mandatory minimums.
• ARS § 28‑1383: Aggravated DUI (e.g., license suspended, third in 84 months, child under 15) — felony with prison exposure and ignition interlock after reinstatement.
• ARS § 28‑1385: Administrative per se license suspensions for BAC tests at or above the legal limit.
• ARS § 28‑1321: Implied‑consent testing & refusal suspensions.
• ARS § 28‑3319: Ignition interlock requirements and periods following DUI convictions.
Mandatory minimums and ranges
First‑offense super extreme under § 28‑1382(A)(2): not less than 45 consecutive days in jail. Under § 28‑1382(I), courts may suspend a portion of this on proof of alcohol screening and installation of a certified IID, leaving a minimum of 14 days to serve. Courts also impose fines, assessments, and surcharges, alcohol screening/treatment, and may order community restitution.
Second‑offense super extreme (within 84 months) carries substantially higher penalties, including a longer mandatory jail term, higher financial penalties, extended IID, and longer license impacts. If aggravating elements under § 28‑1383 are present, felony sentencing rules apply, and cases proceed in Superior Court with potential prison time.
Home detention and continuous alcohol monitoring are authorized by statute for participating municipalities and counties (see ARS §§ 9‑499.07, 11‑251.15). Each court sets program eligibility and required in‑jail percentages; policies differ among Phoenix, Scottsdale, Tempe, and Justice Courts. Always confirm current availability and terms with the assigned court.
Court procedures and defenses
After arraignment, your attorney seeks disclosure (Rule 15), including body‑cam, calibration and maintenance logs, operator permits, toxicology records, and the search‑warrant packet. Suppression motions target illegal stops, lack of probable cause, involuntary “consent,” or defective warrants (see State v. Valenzuela). Motions in limine challenge retrograde extrapolation if drinking continued post‑driving or timing assumptions are weak.
Field sobriety tests (HGN, walk‑and‑turn, one‑leg stand) are scrutinized for NHTSA compliance and medical confounders. Breath testing requires proof of approved devices and procedures; blood testing requires validated methods, proper anticoagulants/preservatives, intact chain of custody, and uncertainty budgets that account for instrument error. Negotiations can pursue reductions to extreme or standard DUI, structured jail with IID credits, or alternative monitoring consistent with statute and local policy.

What to do next
Protect your license immediately
After a police‑served suspension notice, you have a short window to request a hearing with MVD under ARS § 28‑1385 or to seek a restricted permit later. Missing deadlines can forfeit your ability to challenge or delay a suspension.
Preserve evidence and witnesses
Save receipts, text messages, rideshare logs, and names of witnesses who saw your drinking timeline. These can undermine the State’s “within two hours” theory or support a rising‑BAC defense. Surveillance video from bars or businesses is often overwritten quickly—act fast.
Engage counsel to challenge BAC
Retain a defense team to obtain calibration logs, chain‑of‑custody records, and the blood‑draw warrant. Suppression or exclusion can significantly change sentencing exposure, including eligibility to reduce jail through IID under § 28‑1382(I).
Plan for court & compliance
Complete alcohol screening early, explore treatment, and price IID vendors. In Phoenix, Scottsdale, Tempe, and Maricopa County Justice Courts, proactive steps can influence offers and judicial discretion within Arizona’s mandatory framework.
Common mistakes to avoid
Frequently Asked Questions
A super extreme DUI under ARS § 28-1382(A)(2) is a Class 1 misdemeanor unless aggravating factors under ARS § 28-1383 apply (e.g., driving on a suspended license, a third DUI within 84 months, or a child under 15 in the vehicle). With aggravators, the case becomes an aggravated DUI felony and moves to Superior Court.
The statute requires at least 45 consecutive days in jail for a first offense under ARS § 28-1382(A)(2). However, ARS § 28-1382(I) allows the court to suspend a portion of that time if you complete alcohol screening and install a certified ignition interlock device, reducing the minimum to 14 days in many courts.
An administrative per se suspension under ARS § 28-1385 typically starts at 90 days for a test over the legal limit, with possible restricted privileges after 30 days. A refusal under ARS § 28-1321 triggers a 12-month suspension. Following a conviction for extreme or super extreme DUI, MVD generally requires at least 12 months of ignition interlock under ARS § 28-3319.
Yes, suppression is possible. Following Missouri v. McNeely (2013) and State v. Valenzuela (2016), police generally need a warrant or voluntary consent for a blood draw. If the State cannot prove a valid warrant, exigency, or consent, or if chain of custody, lab methods, or calibration are defective, results can be excluded.
