How Much Jail Time for an Extreme DUI in Arizona? ARS 28-1382

How Much Jail Time Do You Get for an Extreme DUI in Arizona?

The statute sets a minimum of 30 consecutive days, and it allows a judge to suspend all but 9 days on a first offense with an ignition interlock. Both numbers come from the same section: A.R.S. § 28-1382, Arizona’s extreme-DUI statute, which applies when your blood or breath alcohol concentration is 0.15 or more but less than 0.20 within two hours of driving. A first conviction under subsection D carries a mandatory minimum of thirty consecutive days in jail, and the defendant is not eligible for probation or suspension of sentence unless the entire sentence is served. But subsection I lets the judge suspend all but nine days if you equip any vehicle you drive with a certified ignition interlock device for twelve months.

That 9-day figure is the floor. It cannot be reduced further by screening or treatment the way a standard first-offense DUI drops from 10 days to 1, and it is only available on a first extreme DUI. What can change is where and how those days are served, which is where the real difference between one defendant’s experience and another’s comes from.

Extreme DUI is still a Class 1 misdemeanor (subsection K), so on its own it is not a felony, a point worth stating plainly because the label causes real confusion. It becomes a felony only when an aggravating trigger under A.R.S. § 28-1383 is present: a suspended or revoked license, a passenger under 15, a required interlock, wrong-way driving, or a third DUI within 84 months.

What Do the 9 Days Actually Look Like?

Whether the 9 days are served entirely in a cell depends on three statutory mechanisms, each of which the court controls:

• Work or school release after 48 hours. Under A.R.S. § 28-1387(C), once a person sentenced under 28-1382 has served 48 consecutive hours and the court confirms employment or enrollment, the court shall allow release to work or attend school for up to 12 hours a day, 6 days a week, unless it finds good cause on the record not to. You return to the jail for the remaining hours.
• Home detention after 20 percent. Counties (A.R.S. § 11-459) and cities (A.R.S. § 9-499.07) may run home detention programs for DUI sentences. For a 28-1382 sentence, the defendant must first serve at least 20 percent of the initial jail term in actual custody before being placed on electronic monitoring at home, with daily alcohol testing, a treatment program, and the cost of the monitoring paid by the defendant. Ask counsel before sentencing how the court you are in computes the 20 percent against a suspended sentence; it is not applied uniformly.
• Continuous alcohol monitoring. The same statutes authorize a continuous alcohol monitoring program (an ankle-worn transdermal monitor) that is “treated the same as confinement in jail.” Not every court offers it, and the sentencing judge can exclude a defendant from any of these programs.

None of these programs is automatic. Each depends on the court, the jail’s program, employment verification, and whether anything in the record (a collision, a high-speed stop, an uncooperative arrest) leads the judge to exclude a defendant, which the statutes expressly allow. What the defense puts in front of the judge at sentencing is what those decisions are made on.

What Comes With the Jail Time

Jail is the number people search for, but the sentence under 28-1382(D) is a package: a fine of at least $250, a $250 DUI-abatement assessment, a $1,000 prison-construction assessment, and a $1,000 public-safety-equipment assessment, all before surcharges, plus court-ordered alcohol screening and treatment, traffic survival school, and the interlock itself. Under A.R.S. § 28-3319(D), MVD requires the interlock for 12 months on a first extreme DUI (18 months if the BAC was .20 or more). Your license is suspended for 90 days on conviction under 28-1387(D) unless MVD has already suspended it administratively under A.R.S. § 28-1385, and a restricted license may be available for part of that period. Our post-conviction requirements guide walks through the full checklist.

How Extreme DUI Jail Time Gets Reduced or Avoided

Because the difference between 9 days and 1 day, and between a misdemeanor and a felony, turns on a single number and a single date, the leverage in an extreme DUI case is concentrated in a few places:

• The .15 line. Extreme DUI is a measurement charge. A blood result of .16 or .17 sits close enough to the threshold that the lab’s uncertainty range, the two-hour rule, retrograde extrapolation, fermentation in an improperly stored vial, and chain-of-custody gaps all matter. The blood sample can be independently retested; our guide to challenging a DUI blood test explains how. Knock the number below .15 and the case is a standard DUI: 10 days, suspended to 1 with screening.
• The plea to 28-1381. Where the extreme count is contestable, a plea to a standard first-offense DUI under A.R.S. § 28-1381 may be negotiable. That single change moves the floor from 9 days to 1 day and drops the assessments substantially. Whether the State will offer it depends entirely on the evidence in the specific case. Where the evidence is weaker still, a reckless driving resolution removes the DUI conviction entirely.
• The stop and the arrest. No reasonable suspicion for the stop, no probable cause for the arrest, or a defective blood-draw warrant means suppression, and suppression of the BAC result ends an extreme-DUI count outright. See our top DUI defenses.
• The prior-conviction allegation. The State must allege a prior under 28-1387(A). If the prior is outside the 84-month window measured by offense dates, is not the equivalent of an Arizona DUI, or was an uncounseled plea, the 120-day second-offense floor can collapse back to the first-offense 30/9.

We start with the number, because the number is the charge: an independent retest, the lab’s uncertainty budget, and the timing of the draw decide whether the State can prove .15 at all. We fight the stop and the warrant in parallel, and we scrutinize any prior-conviction allegation before it doubles the floor. Where the case will resolve by plea, the target is a standard DUI or a reckless-driving disposition, and at sentencing we present the employment and program record the court weighs on work release and home detention. Members of the National College for DUI Defense, we handle these cases in Scottsdale, Phoenix, and every Maricopa County court.
