A DUI case in Arizona typically takes 60 to 120 days for a first-offense misdemeanor under ARS 28-1381, three to seven months for Extreme or Super Extreme charges under ARS 28-1382, and eight months to over a year for Aggravated DUI felonies under ARS 28-1383. Actual timelines depend on the court venue, whether suppression motions are filed, and whether the case proceeds to a jury trial.

What Determines How Long Your Arizona DUI Case Will Take
Arizona DUI case timelines are shaped by four primary variables: the charge level, the assigned court, the complexity of the evidence, and whether the defense pursues contested motions or proceeds toward a negotiated resolution. Each variable can add weeks or months to the overall timeline, and understanding them helps you plan around work, family, and financial obligations while your case is pending.
Charge level sets the baseline. Misdemeanor DUI under ARS 28-1381 carries the shortest average timeline because city and municipal courts handle high volumes and move cases through pretrial conferences on compressed schedules. Tempe Municipal Court, for example, typically sets initial pretrial conferences within 30 to 45 days of arraignment. Phoenix Municipal Court follows a similar pace but manages a significantly larger docket, which can push settings out by an additional two to three weeks. Extreme and Super Extreme DUI charges under ARS 28-1382 often require more defense preparation time for expert review of blood alcohol concentrations and calibration records, extending timelines by 30 to 60 days beyond a standard misdemeanor.
Aggravated DUI under ARS 28-1383 moves the case into Maricopa County Superior Court, a felony forum with mandatory procedures that substantially lengthen timelines. Grand jury proceedings or preliminary hearings occur early in the process, formal disclosure deadlines replace the informal exchange common in municipal courts, and pretrial motion practice is more extensive. A felony DUI defendant should expect a minimum of eight months from indictment to resolution, with contested cases regularly stretching past one year.
Evidence complexity is the next driver. Blood-draw cases require the state crime lab to process samples, and turnaround times at the Scottsdale DPS Crime Lab or contract laboratories can add 30 to 90 days before disclosure is complete. If the defense requests independent retesting of a blood sample, that process adds its own lead time for shipping, analysis, and reporting. Breath-test cases generally move faster because Intoxilyzer 8000 results are available immediately, though challenges to calibration, maintenance logs, and operator certification still require discovery and review.
The decision to file suppression motions is often the single largest variable in case duration. A motion to suppress evidence based on an unlawful traffic stop, an improper arrest, or a coerced blood draw under State v. Butler, 232 Ariz. 84 (2013), and State v. Valenzuela, 239 Ariz. 299 (2016), requires written briefing, subpoenaing the arresting officer, and scheduling an evidentiary hearing. That process typically adds 60 to 90 days to the case timeline. However, successful suppression can lead to charge reduction or dismissal, making the additional time a strategic investment rather than a delay.
At Oliverson Law DUI & Criminal Defense, founder Derek Oliverson draws on 17+ years of courtroom experience and more than 5,000 cases handled across Arizona courts. His background as a former police officer, prosecutor, and judge means he understands scheduling patterns, judicial preferences, and the procedural nuances that influence case pace in each venue. Attorney David Tangren, a former Pima County prosecutor, brings additional trial and negotiation experience that helps set realistic timelines from the first consultation.
DUI Timelines by Charge Level and Arizona Court
The following breakdown reflects typical timelines observed in Maricopa County courts. Individual cases may resolve faster or take longer depending on circumstances, but these ranges give defendants a realistic planning framework.
| Charge | Statute | Court | Typical Timeline | If Tried to Jury |
|---|---|---|---|---|
| Standard DUI (1st offense) | ARS 28-1381 | City/Municipal Court | 60, 120 days | 5, 8 months |
| Standard DUI (2nd in 84 months) | ARS 28-1381 | City/Municipal Court | 90, 150 days | 6, 9 months |
| Extreme DUI (BAC 0.15+) | ARS 28-1382 | City/Municipal Court | 90, 180 days | 6, 9 months |
| Super Extreme DUI (BAC 0.20+) | ARS 28-1382 | City/Municipal Court | 120, 210 days | 7, 10 months |
| Aggravated DUI (felony) | ARS 28-1383 | Superior Court | 8, 14 months | 12, 18+ months |
Misdemeanor cases in Tempe Municipal Court follow a structured calendar: arraignment within 30 days of citation or arrest, followed by pretrial conferences every 30 to 45 days. If a plea is reached at pretrial, sentencing typically occurs the same day or within two weeks. Phoenix Municipal Court operates on a similar structure but with heavier caseloads that can extend the gap between settings. Mesa Municipal Court and Scottsdale City Court each have their own scheduling practices, but most misdemeanor DUIs in these venues resolve within four months absent contested motions.
Maricopa County Justice Courts handle misdemeanor DUI arrests that occur in unincorporated areas or on state highways within the county. These courts generally set cases on 30- to 45-day intervals, and total resolution time mirrors that of city courts. However, travel distance and limited hearing availability in some precincts can create logistical delays.
Felony Aggravated DUI cases in Maricopa County Superior Court follow a distinct procedural track. After arrest, the state has until the preliminary hearing or grand jury return to formally charge, typically within 10 to 30 days. A Superior Court arraignment follows, then a series of case management conferences, disclosure deadlines, and motions. Arizona Rule of Criminal Procedure 8.2(a) requires that a defendant not released from custody be tried within 150 days, while released defendants must be tried within 270 days, absent excludable delay. These speedy-trial clocks can be extended by defense continuances, pending expert analysis, or motion practice, which is why contested felony DUI cases regularly exceed one year.
The MVD implied-consent process under ARS 28-1321 runs on a parallel administrative track. After a DUI arrest, you generally have 15 days to request a hearing with the ADOT Executive Hearing Office. That hearing is usually scheduled within 60 days. While the MVD process does not directly extend the criminal timeline, preparing for both proceedings simultaneously during the first 30 to 60 days can affect strategy and scheduling decisions in the criminal case.

Steps to Keep Your Case Moving Efficiently
Act on the MVD Deadline Immediately
File your MVD hearing request within the 15-day window under ARS 28-1321. Missing this deadline results in an automatic administrative suspension, which cannot be undone regardless of how the criminal case resolves. Handling this early also lets your attorney coordinate both tracks efficiently.
Retain Counsel Before Arraignment
Engaging a DUI lawyer before your first court date allows early discovery requests for body-camera footage, breath machine calibration logs, and blood-draw records. In Tempe Municipal Court and Phoenix Municipal Court, early disclosure review can identify dispositive issues that shorten the case by months rather than prolonging it through multiple pretrial conferences.
Provide Your Attorney with a Complete Timeline
Write down everything you remember about the stop, field sobriety tests, chemical testing, and any statements you made. Include timestamps, locations, and officer names. A detailed client timeline lets your lawyer identify suppression opportunities early and build the defense strategy that produces the fastest path to the strongest outcome.
Respond to Attorney Requests Promptly
Defense attorneys need signed authorizations, medical records, and other documentation to advance your case. Delays in providing these materials can push back court dates and extend the timeline. Staying responsive keeps the case on schedule and avoids unnecessary continuances that add months to resolution.

Frequently Asked Questions
A first-offense misdemeanor DUI under ARS 28-1381 typically resolves in 60 to 120 days when handled in Tempe Municipal Court or Phoenix Municipal Court. Cases that involve contested motions, suppression hearings, or independent blood retesting can extend to five or six months. If the matter proceeds to a jury trial, expect a total timeline of six to eight months from arraignment to verdict and sentencing.
Yes. Extreme and Super Extreme DUI charges under ARS 28-1382 often require additional expert review and motion practice, extending timelines to four to seven months. Aggravated DUI felonies under ARS 28-1383 are filed in Maricopa County Superior Court, where grand jury proceedings, formal discovery, and pretrial conferences can push resolution to eight months or longer. Felony trials themselves may take a year or more from arrest to conclusion.
The MVD hearing runs on a separate administrative track under ARS 28-1321, so it does not directly delay the criminal case. However, preparing for both proceedings simultaneously increases the workload within the first 30 to 60 days. The MVD hearing itself is typically scheduled within 60 days of the request. Outcomes at the MVD level can inform defense strategy in the criminal matter, sometimes leading to more efficient resolution overall.
Suppression motions challenging the traffic stop, arrest, or blood draw add the most time. Filing a motion to suppress under the Fourth Amendment requires briefing, officer subpoenas, and an evidentiary hearing, which can add 60 to 90 days to the timeline. Independent lab retesting of blood samples also introduces delays while waiting for results. Jury trial settings in Phoenix Municipal Court or Maricopa County Superior Court require additional scheduling coordination.
Misdemeanor DUI charges under ARS 28-1381 and ARS 28-1382 must generally be filed within one year of the offense date. Aggravated DUI felonies under ARS 28-1383 carry a seven-year statute of limitations. In practice, most DUI charges are filed within weeks of the arrest, but blood-test cases sometimes see delayed filing while the crime lab processes samples. Once charges are filed, speedy trial rules under Arizona Rule of Criminal Procedure 8 set outer time limits.
