What Makes a DUI a Felony in Arizona?

Most DUI charges in Arizona are misdemeanors, but under specific circumstances a DUI becomes a Class 4 felony — known as aggravated DUI under A.R.S. § 28-1383. The consequences jump dramatically: from days in jail to years in prison, from fines to felony record. Understanding exactly what triggers felony DUI charges is critical because the defenses and penalties are fundamentally different.

Key Takeaways

• Three Situations Create Felony DUI: Driving on a suspended/revoked license from a prior DUI, committing a third DUI within 84 months, or having a child under 15 in the vehicle while driving impaired.
• Aggravated DUI Is a Class 4 Felony: The minimum prison sentence is 4 months, with a presumptive term of 2.5 years. For repeat offenders, sentences escalate significantly.
• A Felony Record Changes Everything: Beyond prison time, a felony DUI conviction results in loss of gun rights, professional license consequences, employment barriers, and a permanent criminal record.

The Three Ways a DUI Becomes a Felony in Arizona

Under A.R.S. § 28-1383, an Arizona DUI is elevated from misdemeanor to felony — specifically aggravated DUI — when one of three circumstances applies. Each carries its own set of challenges and defense strategies.

1. DUI While License Is Suspended or Revoked

If your driver’s license has been suspended, revoked, or canceled as a result of a prior DUI — and you are caught driving impaired again — the new DUI is automatically a Class 4 felony. This applies even if you didn’t know your license was suspended. It also applies if you were driving on a restricted license that didn’t permit the driving you were doing at the time of the arrest.

2. Third DUI Within 84 Months

Arizona uses an 84-month (7-year) lookback period for DUI offenses. If you are convicted of a third DUI within this window, the third offense is charged as aggravated DUI regardless of the BAC level or circumstances. The lookback period is measured from the dates of the offenses, not the dates of conviction, which sometimes creates complex timeline disputes that an experienced attorney can challenge.

3. DUI with a Child Under 15 in the Vehicle

Driving under the influence with a passenger under 15 years old is automatically aggravated DUI. This applies to any DUI charge — standard, extreme, or super extreme. Prosecutors take these cases particularly seriously, and judges tend to impose harsher sentences when children are involved.

Penalties for Felony DUI in Arizona

Aggravated DUI is a Class 4 felony. For a first felony DUI with no prior felonies, the sentencing range is: minimum 4 months in prison, presumptive 2.5 years, and maximum 3.75 years. With one prior felony, the range increases to 2.25–7.5 years. With two or more priors, you face 6–15 years. In addition to prison time, you face mandatory ignition interlock device installation, license revocation for at least one year, substantial fines and surcharges, mandatory alcohol screening and treatment, community service, and probation upon release.

Defenses to Felony DUI Charges

Effective defense strategies for aggravated DUI include challenging the underlying traffic stop or arrest, disputing whether your license was actually suspended at the time, challenging the accuracy of BAC testing, questioning whether the lookback period was correctly calculated for a third offense, and presenting mitigating circumstances for sentencing. In child-passenger cases, your attorney may also challenge whether the child was actually under 15 or whether you were actually the driver.
