Second DUI in Arizona: What Happens? ARS 28-1381

What Counts as a Second DUI in Arizona?

Arizona DUI laws treat a second offense as a different animal from the first. The charge is still a class 1 misdemeanor, but the sentencing floor jumps from days to months of exposure, the fines and assessments multiply, and your license is no longer suspended , it is revoked. If you were just arrested and you already have one DUI on your record, the questions that matter are how the prior is counted, what the statute actually mandates, and which of those mandates can lawfully be reduced.

This guide answers those questions from the text of ARS 28-1381 itself. If this is your first arrest, start instead with our guide to first-offense DUI penalties in Arizona , the numbers below assume a qualifying prior.

A DUI is sentenced as a second offense when you are convicted of violating ARS 28-1381 and you have a prior conviction within 84 months , seven years , under ARS 28-1381 (regular DUI), 28-1382 (extreme DUI), or 28-1383 (aggravated DUI). Three details in the statute catch people by surprise:

• The clock runs between offense dates, not conviction dates. Subsection M says the dates of the commission of the offenses are the determining factor, irrespective of the sequence in which they were committed. A prior that was resolved slowly does not push you outside the window.
• Out-of-state priors count. A conviction from another jurisdiction qualifies if the act would have violated ARS 28-1381, 28-1382, or 28-1383 had it happened in Arizona. Whether it truly would have is a litigable question, not a formality.
• Two charges from one night are not two offenses. Subsection N excludes convictions arising out of the same series of acts, so a single incident that produced multiple counts is still one prior.

What Are the Penalties Under Arizona DUI Laws for a Second Offense?

ARS 28-1381(K) sets the second-offense sentence: not less than 90 days in jail with 30 days served consecutively, a fine of not less than $500, at least 30 hours of community restitution, a one-year revocation of your driving privilege, and two separate $1,250 assessments , one for the prison construction and operations fund, one for the public safety equipment fund. If alcohol was involved, MVD must also require a certified ignition interlock device on any vehicle you operate, and you must complete traffic survival school. The statute adds that you are not eligible for probation or suspension of sentence “unless the entire sentence has been served” , subject to the treatment carve-out covered in the next section.

Can You Avoid Serving All 90 Days in Jail?

Partly, yes , the statute builds in one reduction. Under ARS 28-1381(L), the judge may suspend all but 30 days of the jail sentence if you complete a court-ordered alcohol or drug screening, education, evidence-based psychotherapy, or treatment program. That is the difference between a month and three months in jail, and it is not automatic: it is a sentencing decision the judge makes, and if you fail to complete the program the court issues an order to show cause as to why the remaining sentence should not be served.

In Arizona courts, defense attorneys commonly see the strongest sentencing outcomes when the client enrolls in screening and treatment early , before sentencing, sometimes before the first pretrial conference , rather than waiting to be ordered. Walking into court with a completed screening and a treatment plan in progress gives the judge a concrete reason to use subsection L, and gives your lawyer something real to negotiate with.

What Happens to Your License After a Second DUI?

A second conviction within 84 months revokes your driving privilege for one year , a harsher event than the suspension that follows a first offense, because after a revocation you must apply to MVD for reinstatement rather than simply waiting out a clock. The court reports the conviction, MVD imposes the revocation, and if alcohol was involved, MVD requires a certified ignition interlock device on any vehicle you operate under ARS 28-3319. The court may extend the interlock period beyond twelve months.

There is a lifeline: under ARS 28-1381(O), after completing 45 days of the revocation you become eligible to apply for a special ignition interlock restricted driver license under ARS 28-1401, which can let you drive to work, school, and treatment with the interlock installed. Getting it requires proof of installation and MVD paperwork done correctly , missing a step means driving on a revoked license, which is its own felony trap, as the next section explains.

Commercial drivers face a separate, career-level problem: the CDL disqualification rules run on their own track, and even the interlock license does not restore commercial driving. If you hold a CDL, read our guide to CDL DUI consequences in Arizona.

When Does a Second DUI Become Extreme or Aggravated?

The 90-day framework assumes a regular second DUI. Two escalators change the picture entirely.

High BAC makes it a second extreme DUI. If your alcohol concentration was 0.15 or more, the charge falls under ARS 28-1382, and its second-offense provision requires at least 120 days in jail with 60 served consecutively for a BAC of 0.15 to under 0.20, and at least 180 days with 90 served consecutively for 0.20 or more, plus a $500 or $1,000 minimum fine, the same $1,250 + $1,250 assessments, and a revocation of at least one year. Our breakdown of super extreme DUI in Arizona covers the 0.20+ tier in detail.

A third offense , or the wrong circumstances , makes it a felony. Under ARS 28-1383, a third DUI within 84 months is aggravated DUI, a class 4 felony carrying at least four months in prison before any release eligibility. The same felony applies to a DUI committed while your license is suspended, revoked, or restricted for a prior DUI, while an interlock order is in place, or while driving the wrong way; with a child under fifteen in the car it is a class 6 felony. This is why the one-year revocation matters so much: a person who drives during the revocation from their second DUI and picks up any new DUI has converted a misdemeanor problem into a mandatory-prison felony.

What Should You Expect at Scottsdale City Court?

If your second DUI arrest happened inside Scottsdale city limits , a Loop 101 stop, Old Town, a Shea Boulevard traffic stop , the misdemeanor case is prosecuted by the city and heard in Scottsdale City Court. The process runs on the municipal court’s schedule: an arraignment where you enter a plea, followed by pretrial conferences where the city prosecutor and your lawyer exchange evidence and discuss resolution, with motions and trial settings after that if the case does not resolve.

Three practical points matter for a second-offense case there. First, you have a jury trial right: ARS 28-1381(F) requires the court to tell you at arraignment that you may request a trial by jury and that the request shall be granted , a meaningful lever in a mandatory-minimum case. Second, the MVD side of your case runs on separate deadlines from the court dates, and defense attorneys commonly see people lose license options simply by missing the window to request an MVD hearing after arrest. Third, appearing with counsel from the first hearing changes the trajectory: second-offense files get charging scrutiny (was it really within 84 months? should it be extreme?), and those questions should be contested from day one. Tamou Law Group’s Scottsdale office on East Shea Boulevard is minutes from the court , our Scottsdale DUI defense team appears there regularly.

What Defenses Work Against a Second DUI Charge?

A second-offense case has two layers of defense: the DUI itself, and the prior that makes it a second offense.

• Attack the prior. Was the earlier offense actually committed within 84 months, counting offense date to offense date? Does an out-of-state conviction genuinely match the elements of an Arizona DUI statute? Was the prior conviction constitutionally valid? If the prior falls, the mandatory 90 days falls with it.
• Attack the stop and arrest. The same suppression issues as any DUI , reasonable suspicion for the stop, probable cause for arrest, field sobriety test administration , carry more weight when a mandatory jail term hangs on the outcome.
• Attack the chemical evidence. The 0.08 charge under ARS 28-1381(A)(2) depends on an alcohol concentration within two hours of driving, proven by blood or breath analysis that is only as good as the collection, storage, calibration, and chain of custody behind it.
• Litigate actual physical control. If you were parked, asleep, or not driving, whether you were in “actual physical control” of the vehicle is a fact question a jury decides.
• Negotiate the charge, not just the sentence. Where the evidence is genuinely weak, resolution to a non-DUI offense such as reckless driving eliminates the mandatory second-offense scheme entirely , see how that works in our guide to the wet reckless in Arizona.

How Tamou Law Group Defends Second DUI Cases

We treat a second-offense file as two cases. On the prior, we pull the old docket and test whether it qualifies , the 84-month math, the out-of-state equivalence, the validity of the conviction , because the single most valuable outcome in many second-DUI cases is being sentenced as a first offender. On the new charge, we litigate the stop, the arrest, and the blood or breath evidence, and we run the MVD hearing track in parallel so the license consequences are contested rather than defaulted.

At the same time, we prepare the sentencing case from week one: screening completed, treatment underway, interlock plan ready, so that if the case does resolve as a second offense, the ARS 28-1381(L) reduction to 30 days is the argued-for outcome rather than a hope.
