A second DUI charge in Glendale marks a turning point in how Arizona law treats a driver. The penalties for second DUI in Arizona carry mandatory minimums no judge holds the discretion to waive, and each consequence compounds quickly when a prior conviction exists within seven years. The Law Offices of John Phebus represents Glendale drivers facing these charges and understands how sharply the stakes rise the moment a prior DUI enters the picture.

What Is a Second DUI in Arizona?

Arizona measures a prior DUI against a driver when the new offense occurs within seven years of the original crime. That window runs from the date the first offense took place, not from the sentencing or conviction date, a distinction many drivers overlook until charges emerge.

A DUI charge can stem from several situations: driving while impaired to any degree by alcohol, drugs, or any intoxicating substance; operating a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher; or driving with any amount of illegal drugs in the system. Under Arizona law, a second offense within that seven-year period remains a Class 1 misdemeanor for regular, extreme, and super extreme DUI categories. Mandatory penalties escalate significantly compared to a first offense. A third DUI within seven years moves the charge into felony territory as an aggravated DUI. Knowing the signs you are too drunk to drive can make a critical difference before getting behind the wheel.

Punishments for a Second DUI

The penalties for second DUI in Arizona depend on the driver’s BAC level at the time of arrest. Arizona divides misdemeanor DUI into three tiers, each carrying escalating consequences, and a second offense amplifies those consequences considerably across all three categories.

A second DUI within seven years qualifies as a Class 1 misdemeanor and carries mandatory consequences: jail sentences ranging from a minimum of 30 to 90 days, fines and fees surpassing $3,500, revocation of driving privileges for one year, and ignition interlock device installation lasting at least one year.

Second-Offense “Regular” DUI

Regular DUI applies when a driver’s BAC registers between 0.08% and 0.149%. A second conviction at this level carries mandatory jail time, substantial fines and surcharges, and a one-year license revocation. According to the Arizona Department of Transportation’s DUI suspension page, drivers subject to a DUI-related suspension may qualify for a restricted permit after 30 days, with an option to obtain a restricted license paired with an ignition interlock device. Meeting eligibility requirements for restricted driving access does not reduce the mandatory ignition interlock installation period.

Second-Offense “Extreme” DUI

Arizona Revised Statutes Section 28-1382 defines an extreme DUI as driving with a BAC of 0.15 or more but below 0.20 within two hours of operating a vehicle. A second extreme DUI conviction within seven years brings longer mandatory jail minimums, higher fines, and extended ignition interlock requirements than a regular second offense. The gap between what a first extreme DUI carries and what a second extreme DUI demands grows considerably in required jail time and license consequences.

Second-Offense “Super Extreme” DUI

Super extreme DUI applies when BAC reaches 0.20 or higher within two hours of driving. A second conviction at this level results in the longest mandatory jail sentences of any misdemeanor DUI tier and the highest associated fines. Extended ignition interlock requirements also apply. Arizona treats impairment at this BAC level as carrying substantially elevated danger, and mandatory sentencing reflects the severity of that assessment.

What Happens if Your First DUI Conviction Was “Set Aside”?

Arizona allows certain individuals to petition a court for a “set aside” of their conviction after completing all sentencing requirements. Many Glendale drivers assume a set aside on a prior DUI effectively erases the conviction for future charging purposes. That assumption leads to costly surprises.

Under Arizona law, a conviction formally set aside may still serve as a prior conviction for DUI sentencing enhancement purposes. Prosecutors retain the ability to reference a set-aside DUI when charging a subsequent offense as a second DUI within seven years. The prior conviction retains its legal weight for sentencing, regardless of any post-conviction relief obtained. Completing a set aside on a first DUI does not reduce the mandatory minimums a driver faces on a second charge.

Pleading Down a Second-Offense DUI

Mounting a defense against penalties for second DUI in Arizona starts with understanding the evidence. The State must prove every element of the underlying DUI charge beyond a reasonable doubt, which means evidentiary weaknesses create real opportunities for negotiation or dismissal.

Defense avenues worth examining include problems with BAC testing procedures or equipment calibration, gaps in the chain of custody for blood samples, an unlawful traffic stop, or insufficient evidence of actual impairment at the time of driving. A medical witness may provide testimony addressing how certain health conditions or medications affect BAC readings in ways that complicate the State’s case. Every defense depends on the specific facts involved.

Plea negotiations also remain available. In certain situations, an attorney may argue for treating a second offense as a first-offense charge, particularly when the prior DUI occurred close to the seven-year boundary. Prosecutors weigh those arguments case by case.
