What Is the Penalty for a Second DUI in Arizona?
Quick answer: A second DUI within 84 months (seven years) is still a Class 1 misdemeanor, but the penalties escalate sharply: a minimum of 90 days in jail (with 30 days that must be served), $3,000+ in fines, a one-year license revocation, 30 hours of community service, and a 12-month interlock. An extreme second offense carries 120 days and a super extreme second carries 180 days. Whether a prior actually counts within the 84-month window is often the key to the defense.

If you’ve been charged with second-offense DUI in Arizona, you probably have urgent questions about what you’re facing and what comes next. Here are straight answers to the questions people ask most, with a plain-English breakdown of the law under A.R.S. § 28-1381, the penalties, and the defenses that matter most.
What Is the Penalty for a Second DUI in Arizona?
A second DUI within 84 months (seven years) is still a Class 1 misdemeanor, but the penalties escalate sharply: a minimum of 90 days in jail (with 30 days that must be served), $3,000+ in fines, a one-year license revocation, 30 hours of community service, and a 12-month interlock. An extreme second offense carries 120 days and a super extreme second carries 180 days. Whether a prior actually counts within the 84-month window is often the key to the defense.
How Much Jail Time for a Second DUI?
Arizona sets mandatory minimum jail (or prison) that climbs with each prior offense and with your blood-alcohol level. The table below shows the minimums for a first, second, and third DUI across the standard, extreme, and super extreme tiers. A judge can suspend part of a first-offense term, but second and third offenses carry served time.
How the 84-Month “Look-Back” Works
Arizona counts prior DUIs within 84 months (seven years) of the current offense to decide whether it is a first, second, or third DUI. A prior that falls outside the window, was obtained without a lawyer, or is otherwise invalid may not count, which can drop your penalties to a lower tier. We pull and scrutinize the record behind every alleged prior.
Defending a Second-Offense DUI
Every DUI still rests on a valid stop, a reliable breath or blood test, and proof you were actually impaired while driving. We challenge the reasonable suspicion for the stop, the calibration and administration of the testing, rising-BAC, and the chain of custody, the same pressure points that win first-time cases and that can dismantle a repeat charge.
Estimate DUI Jail Time
Arizona DUI Jail-Time Estimator
Second DUI Jail-Time Escalation
Arizona DUI penalties are driven by two things: how many prior DUIs you have in the last 84 months, and your BAC. Here is how the mandatory minimum jail time climbs.
| Offense (within 84 months) | Standard DUI (.08–.149) | Extreme DUI (.15–.199) | Super Extreme (.20+) |
|---|---|---|---|
| 1st offense | 10 days | 30 days | 45 days |
| 2nd offense | 90 days | 120 days | 180 days |
| 3rd offense | Felony: 4 months prison | Felony: 4 months prison | Felony: 4 months prison |
Minimums only; on a first offense a court may suspend part of the jail term after alcohol screening. A 3rd DUI within 84 months is an aggravated (felony) DUI under A.R.S. 28-1383.
What the State Must Prove for Second-Offense DUI
To convict you of Second-Offense DUI under A.R.S. § 28-1381, the prosecutor must prove every one of these elements beyond a reasonable doubt. If even one fails, the charge fails.
- 1Driving or actual physical control. You were driving, or in actual physical control of, a vehicle.
- 2Impairment or a prohibited BAC. You were impaired to the slightest degree, or had a BAC of .08 or more (.15+ for extreme, .20+ for super extreme).
- 3Any qualifying prior in 84 months. For a felony third DUI, the State must prove the required prior DUI convictions within the 84-month window.
- 4A valid stop and testing. That the stop was lawful and the breath or blood testing was properly conducted, both are required and both are challengeable.
Examples of Conduct Charged as Second-Offense DUI
- A second DUI with a BAC of .08 to .149 (standard)
- A second extreme DUI (.15 to .199)
- A second super extreme DUI (.20 or higher)
- A second DUI involving drugs or marijuana
What Sentence Could You Actually Face?
A second-offense DUI carries mandatory minimum jail that rises steeply with your BAC tier.
Standard
.08–.149 BAC
Extreme
.15–.199 BAC
Super Extreme
.20+ BAC
⚠ The 84-Month Window Is Everything
A prior DUI only elevates your case if it falls within 84 months and is a valid conviction. If a prior is too old, was uncounseled, or is otherwise infirm, it may not count, dropping your case back to first-offense penalties and eliminating the 90-day minimum. We obtain and scrutinize the records behind every alleged prior.
How We Fight Arizona Second-Offense DUI Cases
Every case has weak points. These are the defenses we look at first.
Attacking the Stop & the Case
No Reasonable Suspicion for the Stop. If police lacked a lawful reason to pull you over, the evidence that followed can be suppressed.
Breath-Test Errors. Intoxilyzer machines must be calibrated and maintained; radio interference, mouth alcohol, and operator error inflate readings.
Blood-Draw & Chain-of-Custody Problems. An improper draw, unqualified phlebotomist, fermentation, or a broken chain can make a blood result inadmissible.
Rising BAC. Your BAC may have been below the limit while driving and only rose by the time of testing; the State must prove your level at the time of driving.
No Actual Physical Control. Sitting in a parked car is not always driving.
Attacking the Prior & the Tier
Priors Outside 84 Months. A prior DUI that falls outside the seven-year window does not count, which can drop the offense to a lower tier.
Invalid or Uncounseled Priors. A prior obtained without a lawyer or a valid waiver may not be usable to elevate the new charge.
Reducing the Offense Level. Without the required qualifying priors, the case stays at a lower tier with far less jail.
Mitigation & Screening. Treatment, screening, and a strong record can reduce jail time and protect your license.
The Experts We Bring to the Table
Drug cases are built on lab reports, searches, and informants. We bring the specialists who take them apart.
Forensic Chemists & Toxicologists
Drug ID & Weight
Independently test the substance and its usable weight, the elements the State must prove, and expose flawed lab work.
Search & Seizure Analysts
How the Drugs Were Found
Reconstruct the stop, the search, and the warrant to find the Fourth Amendment violations that get evidence suppressed.
Informant & Buy Experts
Controlled Buys
Scrutinize confidential informants, controlled-buy procedure, and inducement, the weak core of many sale cases.
Chain-of-Custody Analysts
Evidence Handling
Trace the drugs from seizure to lab and expose gaps, mislabeling, and contamination that make the evidence unreliable.
Digital Forensics Experts
Texts & ‘For Sale’ Proof
Examine phone and message evidence the State uses to argue intent to sell, and challenge what it actually proves.
Treatment & Mitigation Specialists
Drug Court & Diversion
Build the case for TASC, drug court, and treatment-based resolutions that avoid a conviction or prison.

Arizona Second-Offense DUI FAQs
Quick answers to the questions we hear most about second-offense DUI charges, penalties, and defenses in Arizona.
What Is the Penalty for a Second DUI in Arizona?
A second DUI within 84 months (seven years) is still a Class 1 misdemeanor, but the penalties escalate sharply: a minimum of 90 days in jail (with 30 days that must be served), $3,000+ in fines, a one-year license revocation, 30 hours of community service, and a 12-month interlock. An extreme second offense carries 120 days and a super extreme second carries 180 days. Whether a prior actually counts within the 84-month window is often the key to the defense.
How much jail time is a second DUI in Arizona?
A second standard DUI carries a minimum of 90 days in jail; an extreme DUI carries 120 days and a super extreme 180 days.
How does Arizona count prior DUIs?
Arizona looks back 84 months (seven years). A prior within that window elevates the offense; a prior outside it, or an invalid prior, may not count.
Will I go to jail for a second DUI?
There is a mandatory minimum jail term, but on a first offense most of it can be suspended after screening. Beating or reducing the charge can avoid jail entirely.
Can a second DUI be dismissed or reduced?
Yes. DUIs are frequently dismissed or reduced by challenging the stop, the breath or blood testing, impairment, or the validity of a prior. Every case is different.
Should I talk to the police?
No. Provide your documents, then politely decline to answer questions and ask for a lawyer. Statements about drinking are exactly what the State uses against you.
Can I refuse a breath or blood test in Arizona?
Arizona’s implied-consent law means refusing a test triggers an automatic 12-month license suspension, and police can still get a warrant for your blood. Whether you refused or not, the testing is challengeable.
Will I get a real attorney or a junior associate?
At Tamou Law Group your defense is handled by a full team of experienced attorneys, not associates, including Michael Tamou. Call 623-321-4699, 24/7.
