Aggravated & Extreme DUI in Arizona: A.R.S. §28-1382 and §28-1383 Explained

Arizona has a national reputation for tough DUI laws, and the reputation is earned at the top two tiers of the charging ladder. A standard first-offense DUI under A.R.S. §28-1381 is a misdemeanor with a short mandatory jail term. But once your blood alcohol concentration crosses 0.15 — or once an aggravating circumstance like a suspended license or a third offense enters the picture — the case moves into the territory of extreme DUI under A.R.S. §28-1382 and aggravated (felony) DUI under A.R.S. §28-1383. The differences are not incremental. They are the difference between a weekend in jail and four months in state prison.

This guide explains how each statute works, what the penalties actually look like in Maricopa County courtrooms, how the MVD side of the case runs on its own track, and where an experienced defense lawyer can still make a difference.

The Three Tiers of Arizona DUI, at a Glance

Arizona prosecutes impaired driving under three main statutes, and the same traffic stop can produce charges under more than one of them:

• Standard DUI — A.R.S. §28-1381. Driving while impaired to the slightest degree, or with a BAC of 0.08 or more within two hours of driving (0.04 for commercial drivers). A class 1 misdemeanor.
• Extreme DUI — A.R.S. §28-1382. Driving with a BAC of 0.15 or more within two hours of driving. A BAC of 0.20 or higher triggers the harsher penalty band that practitioners call "super extreme." Still a misdemeanor, but with dramatically longer mandatory jail.
• Aggravated DUI — A.R.S. §28-1383. A DUI committed under specific aggravating circumstances — suspended or revoked license, third DUI within 84 months, a passenger under 15, driving the wrong way on a highway, or violating an ignition interlock requirement. This is a felony.

Extreme DUI Under A.R.S. §28-1382

Section 28-1382 makes it unlawful to drive or be in actual physical control of a vehicle with an alcohol concentration of 0.15 or more within two hours of driving. The statute then splits into two penalty bands: 0.15 to 0.199, and 0.20 or above. Both are class 1 misdemeanors, but the legislature attached mandatory minimum jail terms that judges cannot waive in the ordinary course.

First-Offense Extreme DUI Penalties

The interlock-based jail reduction is one of the most consequential features of the statute. For a first extreme DUI, the court may suspend a substantial portion of the mandatory term if the defendant equips every vehicle they operate with a certified ignition interlock device. In Maricopa County practice, that is frequently the difference between a month in Lower Buckeye Jail and a stay measured in days — but it is discretionary, it must be ordered by the judge, and it depends on the defendant actually completing the interlock installation.

Second-Offense Extreme DUI Within 84 Months

A second extreme DUI within 84 months (seven years) removes most of the breathing room. The mandatory minimum rises to 120 days of jail for a 0.15–0.199 BAC — at least 60 of them served consecutively — and 180 days for a super extreme second offense. Fines and assessments climb past $3,000, the MVD revokes the license for one year, and 30 hours of community service become mandatory. A second offense also puts the driver one mistake away from felony exposure: the next DUI within the 84-month window is charged as aggravated DUI under §28-1383.

Aggravated DUI Under A.R.S. §28-1383

Aggravated DUI is Arizona's felony DUI statute. It does not require a higher BAC than a standard DUI — it requires an aggravating circumstance. Under §28-1383(A), a person commits aggravated DUI by driving under the influence:

1. While their license is suspended, canceled, revoked, or refused as the result of a prior DUI-related action;
2. As a third DUI within 84 months (the two priors can be standard or extreme DUIs, in Arizona or an equivalent out-of-state offense);
3. While a passenger under 15 years of age is in the vehicle;
4. While subject to an ignition interlock requirement; or
5. While driving the wrong way on a highway.

Felony Classification and Prison Exposure

Aggravated DUI based on a suspended license, a third offense in 84 months, an interlock violation, or wrong-way driving is a class 4 felony. Aggravated DUI based on a passenger under 15 is a class 6 felony, the lowest felony class, which in some cases can be designated a misdemeanor at sentencing.

The teeth of the statute are in the mandatory minimums. A person convicted of class 4 aggravated DUI as a third offense within 84 months must serve at least four months in the Arizona Department of Corrections — state prison, not county jail — before becoming eligible for probation or any suspension of sentence. Depending on prior felony history, the presumptive sentence for a class 4 felony runs to 2.5 years, with an aggravated range beyond that. Other consequences include:

• A one-year license revocation by the MVD, followed by an interlock period commonly running 24 months after reinstatement;
• Fines, surcharges, and assessments that routinely total $4,000 or more;
• A permanent felony record affecting employment, housing, professional licensing, and firearm rights;
• Supervised probation of up to 10 years in many cases;
• Mandatory alcohol or drug screening, education, and treatment.

The MVD Case Runs on a Separate Track

Every Arizona DUI arrest produces two cases: the criminal prosecution and an administrative action by the Motor Vehicle Division. When an officer serves an Admin Per Se / Implied Consent affidavit, the MVD suspension begins automatically — typically a 90-day suspension for a BAC result of 0.08 or more, or a one-year suspension for refusing the test — unless a hearing is requested within 15 days.

That 15-day deadline is unforgiving, and it matters more in extreme and aggravated cases. An MVD hearing before an administrative law judge is often the defense's first opportunity to cross-examine the arresting officer under oath, lock in testimony about the stop and the breath or blood procedure, and discover weaknesses in the state's case months before the criminal trial date. Drivers who let the deadline pass lose both the hearing and that early discovery window.

Drivers on Phoenix freeways should also understand where these cases come from: DUI task-force saturation patrols concentrate on the I-10, I-17, and Loop 101 corridors, especially on holiday weekends, and Arizona's task-force model means multiple agencies running coordinated enforcement. A high-BAC reading at a checkpoint or saturation stop is the typical origin of an extreme DUI filing.

Defenses That Still Matter at the High Tiers

Mandatory minimums limit a judge's discretion, but they do not decide guilt. The defense issues in extreme and aggravated cases tend to cluster in a few areas:

• The stop and arrest. If the initial traffic stop lacked reasonable suspicion, or the arrest lacked probable cause, the BAC evidence can be suppressed entirely.
• The chemistry. Blood draw procedures, chain of custody, headspace gas chromatography calibration, and the margin of error on the instrument all matter enormously when a result reads 0.151 or 0.203 — barely over a statutory line.
• The two-hour window and retrograde extrapolation, discussed above.
• Knowledge of the suspension. In suspended-license aggravated DUI cases, the state must generally show the driver knew or should have known the license was suspended. MVD mailing records and notice procedures are a recurring weak point.
• Charge reduction. Even where the evidence is strong, negotiating an aggravated charge down to a misdemeanor DUI, or a super extreme down to a lower band, changes the mandatory minimum that applies — often the single most valuable outcome available.

Because the gap between tiers is so wide — 9 days versus 45 days versus 4 months in prison — high-tier DUI defense in Arizona is frequently about which statute and which band the defendant is ultimately sentenced under, not just guilt or innocence. This is the core of what experienced Arizona DUI attorneys handle daily in Phoenix-area courts.

What to Do in the First 15 Days After an Arrest

1. Calendar the MVD deadline immediately. Request the hearing within 15 days of being served the suspension paperwork.
2. Preserve evidence. Receipts, witness contact information, and a written timeline of what you drank and when can become critical to challenging extrapolation testimony.
3. Get an independent blood test. Arizona law entitles you to a portion of the blood sample for independent analysis — request it before the sample is destroyed.
4. Do not drive on a suspended license. Driving during the suspension is itself a pathway to a felony aggravated DUI charge if anything goes wrong.
5. Consult a DUI defense attorney before your first court date, particularly if the charge is extreme, super extreme, or aggravated — the early decisions (MVD hearing, interlock installation timing, treatment enrollment) directly affect the sentence.
