Second DUI in Arizona: Mandatory jail, 84‑month lookback & one‑year revocation explained
In Arizona, a second DUI within 84 months triggers mandatory jail, steep fines, a one‑year license revocation, and at least 12 months of ignition interlock under ARS 28‑1381, 28‑1382, and 28‑1387. If aggravating factors under ARS 28‑1383 apply (e.g., suspended license or a child passenger), the case becomes an Aggravated DUI felony.
What a second DUI really means in Arizona
Arizona treats a second DUI within 84 months as a mandatory‑minimum offense. For a standard DUI under ARS 28‑1381, the court must impose at least 90 days in jail (with a portion eligible for suspension upon completing alcohol screening and treatment), thousands in fines and assessments, a one‑year driver’s license revocation through MVD, and ignition interlock for at least 12 months. If the BAC is 0.15 or higher, ARS 28‑1382 (Extreme/Super Extreme) raises the minimum jail to 120–180 days. If you were driving while your license was suspended, or a child under 15 was in the vehicle, ARS 28‑1383 elevates the charge to Aggravated DUI (a felony) even if it’s only your second DUI event.
The “second within 84 months” lookback in ARS 28‑1387 counts prior DUI convictions based on offense dates, and qualifying out‑of‑state DUIs can act as priors if they are substantially similar to Arizona’s DUI laws. Misdemeanor second‑offense DUIs are prosecuted in city or justice courts (for example, Phoenix Municipal Court, Scottsdale City Court, Mesa Municipal Court, Glendale City Court, and Maricopa County Justice Courts). Felony Aggravated DUIs are filed in Superior Court, including Maricopa County Superior Court.
If you’re facing a second DUI in Phoenix, Scottsdale, Glendale, Mesa, or anywhere in Maricopa County, early intervention by a DUI lawyer in Arizona can affect release conditions, evidence preservation, and negotiations.
Arizona statutes, penalties & court procedures
Core statutes that govern second DUIs
• ARS 28‑1381: Impaired to the slightest degree and/or BAC 0.08+ within two hours of driving. Second‑offense misdemeanor penalties are enhanced and mandatory.
• ARS 28‑1382: Extreme DUI (0.15+) and Super Extreme (0.20+) with sharply higher mandatory jail on a second offense.
• ARS 28‑1383: Aggravated DUI felony for specified circumstances (e.g., DUI with a suspended/revoked license, a minor passenger under 15, or a third DUI within 84 months).
• ARS 28‑1387: Prior convictions & the 84‑month lookback; includes substantially similar out‑of‑state priors.
Second‑offense penalty ranges (typical statutory minimums)
| Charge Level | Mandatory Jail | Fines/Assessments | MVD Action | Ignition Interlock |
|---|---|---|---|---|
| Second Regular DUI (ARS 28‑1381) | At least 90 days (often 30 consecutive; remaining may be suspended with treatment) | Typically several thousand dollars after surcharges | One‑year revocation (separate from any Admin Per Se) | At least 12 months |
| Second Extreme DUI (0.15–0.199) (ARS 28‑1382) | At least 120 days | Higher mandatory assessments than regular DUI | One‑year revocation | At least 12 months |
| Second Super Extreme (0.20+) (ARS 28‑1382) | At least 180 days | Highest mandatory assessments among misdemeanors | One‑year revocation | At least 12 months |
| Aggravated DUI (felony) (ARS 28‑1383) | Prison exposure; probation with jail often includes 4+ months minimum | Felony fines/assessments; felony record | Longer revocation; points & felony implications | Interlock typically required |
Court process you should expect
• Arraignment: You enter a plea and receive initial release conditions. In misdemeanor second‑offense cases, arraignment occurs in city or justice courts (e.g., Phoenix Municipal Court or Glendale City Court). Felonies are arraigned in Superior Court.
• Pretrial conferences: The prosecutor discloses evidence (police reports, body‑cam, breath/blood results). Defense may request additional disclosure, independent blood testing, and expert review.
• Motion practice: Common issues include the legality of the traffic stop, arrest, and the two‑hour BAC requirement; compliance with Department of Health Services rules for breath/blood testing; and Miranda/invocation issues. Suppression can reduce or dismiss charges.
• Trial: Misdemeanor trials proceed to a judge or jury depending on charge; felonies are jury trials in Superior Court. Sentencing follows statutory minimums unless the defense obtains a reduction or alternative terms permitted by law.
License suspensions, revocations & interlock
Arizona imposes two separate tracks: court and MVD. First, an Admin Per Se (APS) or Implied Consent action may start immediately after arrest. A chemical test of 0.08+ typically triggers a 90‑day APS suspension unless you request a hearing with the ADOT Executive Hearing Office in time. A refusal carries a 12‑ or 24‑month Implied Consent suspension. Second, upon conviction for a second DUI within 84 months, MVD will revoke your driving privilege for one year. After a mandatory revocation period, many drivers may be eligible for a Special Ignition Interlock Restricted Driver License (SIIRDL) if statutory conditions are met. Interlock is generally required for at least 12 months after reinstatement; violations can extend that time. Timely requesting an MVD hearing preserves your right to challenge the suspension, cross‑examine officers, and address breath/blood reliability issues. Winning at MVD can avoid or shorten APS action but does not by itself dismiss the criminal case.
Defenses, evidence challenges & case outcomes
Second‑offense DUIs can be contested on the stop, the arrest, the testing process, and whether a prior truly qualifies within 84 months under ARS 28‑1387. Courts may suppress evidence if officers lacked reasonable suspicion or probable cause, or if breath/blood testing did not substantially comply with Arizona Department of Health Services regulations and approved methods. The “two‑hour” requirement in ARS 28‑1381(A)(2) also matters; when the state relies on retrograde extrapolation to estimate BAC within two hours of driving, cross‑examination and expert testimony can expose uncertainty, device error, or physiological variables.
Negotiated outcomes vary. In city and justice courts, cases have been reduced from Extreme to Regular DUI where evidentiary gaps exist, leading to shorter mandatory jail and reduced financial penalties. In Superior Court Aggravated DUI filings, proof problems with the suspended‑license status, lack of interlock proof, or insufficient child‑passenger evidence have led to dismissals or re‑filings as misdemeanors. While each case turns on its own facts, targeted motions practice and expert analysis often drive results.

What to do next
Request your MVD hearing immediately
Deadlines are short. A timely hearing request can pause the Admin Per Se or Implied Consent suspension and lets us cross‑examine the arresting officer and challenge breath/blood reliability before the ADOT Executive Hearing Office.
Secure dash‑cam, body‑cam & medical records
Video, dispatch logs, calibration records, and any hospital labs can make or break suppression motions. We move fast to preserve time‑sensitive evidence that can reduce or defeat second‑offense enhancements.
Undergo screening early
Arizona courts may suspend a portion of mandatory jail when you complete alcohol screening, education, and treatment. Early completion can also support negotiations and reduce exposure at sentencing.
Engage experienced counsel
Second‑offense DUIs are statute‑driven. A focused defense targets the traffic stop, two‑hour BAC issues, test compliance, and whether the prior qualifies under ARS 28‑1387. Begin strategy now to influence charging and plea posture.
Common mistakes to avoid
Frequently Asked Questions
No. A second DUI within 84 months is usually a Class 1 misdemeanor under ARS 28-1381 or 28-1382. It becomes a felony (Aggravated DUI under ARS 28-1383) if aggravating factors exist, such as driving while your license is suspended or having a child under 15 in the vehicle. A third DUI within 84 months also triggers Aggravated DUI.
Arizona’s lookback is generally measured offense date to offense date. Under ARS 28-1387, a prior DUI counts if it occurred within 84 months of the current offense and resulted in a qualifying conviction. Out-of-state DUIs can count if they are substantially similar to Arizona’s DUI statutes, so certified records and statute comparisons matter.
Two tracks apply. First, an Admin Per Se (90 days) or Implied Consent (12 or 24 months) suspension may start immediately unless you request a timely hearing with ADOT’s Executive Hearing Office. Second, upon conviction for a second DUI within 84 months, MVD will revoke your license for one year. Interlock is typically required for at least 12 months after reinstatement.
Under ARS 28-1382, a second Extreme DUI (0.15–0.199) carries a minimum of 120 days in jail, while a second Super Extreme (0.20+) carries a minimum of 180 days. These mandatory terms are higher than the 90-day minimum for a second regular DUI under ARS 28-1381 and are separate from fines, assessments, and MVD consequences.
