When a DUI Becomes a Felony in Arizona Courts
Yes. In Arizona, a DUI is a felony only when it is charged as “aggravated DUI” under A.R.S. § 28-1383. It applies to DUIs with a suspended license, a third DUI in 84 months, a minor passenger, an interlock violation, or wrong-way driving. Otherwise, DUI is a misdemeanor.
Is a DUI a Felony in Arizona? The Direct Answer
Arizona law makes a DUI a felony only when it becomes an “aggravated DUI” under A.R.S. § 28-1383. The statute lists five aggravators that elevate a DUI from a misdemeanor to a felony: (1) driving while impaired or with a prohibited BAC while your driver license is suspended, canceled, revoked, or restricted; (2) a third or subsequent DUI within 84 months; (3) committing DUI with a passenger under age 15; (4) committing DUI while a court has ordered you to use an ignition interlock device; and (5) driving the wrong way on a highway while impaired or over the legal limit.
Most first-time DUI cases in Phoenix, Mesa, or Kingman are misdemeanors under A.R.S. § 28-1381 (impairment to the slightest degree or BAC .08+) or A.R.S. § 28-1382 (Extreme/Super Extreme), heard in city courts or justice courts. But add any A.R.S. § 28-1383 aggravator, and the charge is filed as a felony in the Superior Court of the county (for example, Maricopa County Superior Court or Mohave County Superior Court).
Aggravated DUI is typically a Class 4 felony, except the child-passenger variant, which is a Class 6 felony. Class 4 aggravated DUI carries a mandatory prison term (not just jail). The child-passenger aggravated DUI is a Class 6 felony with mandatory time and felony consequences, though often probation-eligible. Whether the government can prove the aggravator beyond a reasonable doubt is frequently the focus of defense strategy.
Importantly, “Extreme” or “Super Extreme” DUI by itself does not make a case a felony in Arizona. Those higher BAC offenses are still misdemeanors unless one of the A.R.S. § 28-1383 aggravators also applies. For a detailed overview of defenses and strategy, see our DUI lawyer in Arizona page.
Arizona Law, Penalties, and Felony DUI Court Process
Key statutes
A.R.S. § 28-1381: Misdemeanor DUI (impairment to the slightest degree; or BAC .08+ within two hours). Arizona’s Supreme Court in State v. Zaragoza, 221 Ariz. 49 (2009), affirmed that “slightest degree” means any impairment, even minimal, affecting judgment or control.
A.R.S. § 28-1382: Extreme (.15+) and Super Extreme (.20+) DUI. These are usually misdemeanors with enhanced mandatory jail but are not felonies by BAC alone.
A.R.S. § 28-1383: Aggravated DUI (felony). Aggravators include: suspended/revoked/restricted license; third DUI in 84 months; child under 15 in the vehicle; DUI while under ignition interlock requirement; and wrong-way driving on a highway.
A.R.S. § 28-1321: Implied consent. Officers need either a valid warrant or voluntary consent for blood draws. Arizona appellate decisions—State v. Butler, 232 Ariz. 84 (2013), and State v. Valenzuela, 239 Ariz. 299 (2016)—restrict coerced “consent” and frequently drive suppression motions.
Felony classifications and sentencing ranges
Class 4 aggravated DUI: Mandatory prison time and felony sentencing apply. Even if the court places you on probation, Arizona law requires a prison term before probation eligibility. Typical non-dangerous Class 4 ranges (if prison is imposed beyond the mandatory minimum) are measured in years, with a presumptive term in the middle of the statutory range. Minimum mandatory time for aggravated DUI under the common Class 4 subsections is four months in the Department of Corrections before any probation can begin.
Class 6 aggravated DUI (child under 15): Still a felony with mandatory time, though often probation-eligible. Class 6 non-dangerous ranges are lower than Class 4, and courts frequently impose a combination of jail and probation. The record remains a felony unless later designated a misdemeanor by the court (which is not automatic and is highly fact-dependent).
Financial penalties and collateral consequences
Fines, surcharges, and assessments in aggravated DUI cases are substantial and commonly exceed $4,000. Additional costs include alcohol screening/treatment, probation fees, and ignition interlock charges. A.R.S. § 28-1383 convictions trigger license revocation by MVD—often at least one year and up to three years with certain priors or refusals—and mandatory ignition interlock (frequently 24 months) after reinstatement. If the vehicle was driven on a suspended license, A.R.S. § 28-3511 authorizes a 30-day impound in many cases.
Where your case is heard
Misdemeanor DUIs in Phoenix, Mesa, and many East Valley jurisdictions are filed in city courts or justice courts. Felony aggravated DUIs are filed in the Superior Court of the county where the offense occurred—e.g., Maricopa County Superior Court for Phoenix or Mesa arrests, and Mohave County Superior Court for Kingman arrests.
Felony DUI procedure in Arizona courts
Initial appearance: After booking or citation for aggravated DUI, you will have an initial appearance where a judge sets release conditions. If booked, this is typically within 24 hours.
Preliminary hearing or grand jury: Under Rule 5 of the Arizona Rules of Criminal Procedure, in-custody cases generally receive a preliminary hearing within 10 days, and out-of-custody within 20 days, unless a grand jury indictment is returned first.
Arraignment and pretrial: After indictment or a court’s probable-cause finding, you are arraigned in Superior Court. The case proceeds to case-management and trial settings. Defense motions often target blood or breath evidence (for example, challenging warrants under Valenzuela or the voluntariness of consent under Butler) and contest whether the alleged aggravator is legally sufficient.
Trial or resolution: Aggravated DUI is a jury-eligible felony. Many cases resolve through negotiated pleas that may address the charged aggravator, the felony class, and agreed sentencing caps or probation terms.
Related drug DUI note: For drug-based DUIs, State ex rel. Montgomery v. Harris, 234 Ariz. 343 (2014), held that an inactive marijuana metabolite is not enough to convict—proof must show an impairing substance or active metabolite. This can be pivotal in aggravated drug-DUI prosecutions.

What To Do Next
Protect your license immediately
Arizona’s MVD can start an administrative suspension separate from the criminal case. You typically have a short window—often 15 days from notice—to request a hearing. Prompt action preserves your right to challenge the basis for suspension and to seek restricted driving privileges later.
Preserve evidence and challenge testing
Save tow receipts, body-cam details you recall, and witness names. Blood and breath evidence can be attacked through motions to suppress (warrant or consent issues) and through independent retesting. Chain of custody, lab compliance, and instrument maintenance records are critical in felony cases.
Evaluate the aggravator
Felony status hinges on the aggravator. Was your license actually suspended? Is the prior DUI within 84 months and constitutionally valid? Was the passenger under 15? Did “wrong-way” proof meet statutory definitions? A focused review can reduce leverage or defeat the felony allegation.
Get experienced counsel early
Felony DUIs move quickly in Superior Court. Early intervention helps shape release conditions, preserve defenses, and negotiate outcomes that consider prison exposure, probation options, and collateral consequences. Start with a strategy session tailored to Maricopa County or Mohave County practice.
