Arizona Extreme DUI Lawyers
Charged with extreme DUI in Arizona? Under A.R.S. § 28-1382 a BAC of .15 or higher is an extreme DUI carrying a mandatory minimum 30 days in jail, and .20 or higher is a super extreme DUI carrying 45 days. The charge is built on one number, the test, so the test is exactly what we attack. Do not assume the result is correct.

What Is an Extreme DUI in Arizona?
Quick answer: Extreme DUI (A.R.S. § 28-1382) is charged when your alcohol concentration is .15 or higher; a super extreme DUI is .20 or higher. Both are Class 1 misdemeanors, but they carry mandatory jail, a first extreme DUI means a minimum of 30 days in jail and a super extreme means 45 days, plus heavy fines, a certified ignition interlock, and license suspension. Because the charge rests entirely on a breath or blood number, the defense focuses on the stop and on attacking the accuracy of the test, where even a small error can drop the case below the extreme threshold.
Key Takeaways
- Extreme DUI (A.R.S. § 28-1382) means a BAC of .15 or higher; super extreme means .20 or higher.
- A first extreme DUI carries a mandatory minimum 30 days in jail; a first super extreme carries 45 days, both Class 1 misdemeanors.
- You also face a 12–18 month certified ignition interlock, a 90-day license suspension, alcohol screening, and roughly $2,750–$3,250+ in fines and assessments.
- The charge is built on a single number, so attacking the breath or blood test, its margin of error, calibration, and timing, is the heart of the defense.
- Dropping the reading below .15 can reduce an extreme DUI to a standard DUI; dropping it below .20 reduces a super extreme to an extreme.
- A third DUI within 84 months becomes an aggravated (felony) DUI, a far more serious charge.

Mandatory Jail
Charged With Extreme DUI?
A first extreme DUI (BAC .15+) under A.R.S. § 28-1382 carries a mandatory minimum 30 days in jail. The earlier we challenge the test, the more options you have. Call before your first court date.
Call 623-321-4699 →The Number Is Everything
Is the Test Even Accurate?
Extreme DUI is charged on a single number. Breath machines, blood handling, and timing all carry error. Pushing the reading below .15 can reduce the charge to a standard DUI.
See the Thresholds →.20 or Higher
Super Extreme DUI?
A BAC of .20 or more is a super extreme DUI, with a mandatory minimum 45 days in jail and an 18-month interlock. The defense, and the stakes, are even higher. Call now.
CALL NOWArizona Extreme DUI Law: A.R.S. § 28-1382
Extreme DUI is defined entirely by your alcohol concentration, not by how you drove. Statutes link to azleg.gov.
Extreme DUI, § 28-1382(A)(1)
You commit an extreme DUI when your alcohol concentration is .15 or more within two hours of driving or being in actual physical control of a vehicle. It is a Class 1 misdemeanor, but unlike a standard DUI it carries a mandatory minimum 30 days in jail on a first offense, a term the court cannot simply suspend. Because the charge is built on the test result, reducing the reliable reading below .15 turns the case back into a standard DUI.
Super Extreme DUI, § 28-1382(A)(2)
A super extreme DUI is an alcohol concentration of .20 or more. It is the most serious misdemeanor DUI, carrying a mandatory minimum 45 days in jail on a first offense, an 18-month certified ignition interlock, and the highest fines. The same defenses apply, and dropping a .20 to below the threshold reduces it to an ordinary extreme DUI.
Mandatory Jail & the Interlock, § 28-1382(D)–(E)
For a first extreme DUI the law sets a mandatory minimum jail term (30 days extreme, 45 days super extreme) and requires a certified ignition interlock device for 12 to 18 months after license reinstatement, along with alcohol screening and treatment. These minimums are why an extreme DUI must be fought on the front end, before a plea locks them in.
Repeat Extreme DUI, § 28-1382(B)
A second extreme DUI within 84 months carries a minimum of 120 days in jail (180 days for super extreme), a one-year license revocation, and community service. The prior offense and the 84-month window are both challengeable, and an invalid or untimely prior can pull the case out of repeat-offender sentencing.
When Extreme Becomes a Felony
An extreme DUI is still a misdemeanor, but a third DUI of any kind within 84 months, or a DUI committed on a suspended license or with a child under 15, becomes an aggravated (felony) DUI under A.R.S. § 28-1383, with prison exposure. Keeping prior extreme DUIs from stacking into a felony is a critical long-term goal.
What the State Must Prove for Extreme DUI
To convict you of Extreme DUI under A.R.S. § 28-1382, the prosecutor must prove every one of these elements beyond a reasonable doubt. If even one fails, the extreme charge fails.
- 1Driving or actual physical control. You were driving or in actual physical control of a vehicle.
- 2In Arizona, on a road or area open to the public. Arizona’s DUI laws applied to where you were.
- 3An alcohol concentration of .15 or more. Or .20 or more for a super extreme DUI, this is the element that makes it ‘extreme.’
- 4Within two hours of driving. The extreme concentration must be shown within two hours of driving and result from alcohol consumed before or while driving.
Examples of Conduct Charged as Extreme DUI
- A breath or blood test reading of .15 to .199 (extreme)
- A test result of .20 or higher (super extreme)
- A second extreme DUI within 84 months
- An extreme DUI charged on the number alone, with no bad driving
Standard vs. Extreme vs. Super Extreme
A few hundredths of a point separate these charges, and each step up adds weeks of mandatory jail. That is why fighting for the number matters.
| DUI Type | BAC | Statute | Class | Mandatory Minimum Jail |
|---|---|---|---|---|
| Standard DUI | .08 – .149 | 28-1381 | Class 1 Misd. | 10 days (often reduced to 1) |
| Extreme DUI | .15 – .199 | 28-1382(A)(1) | Class 1 Misd. | 30 days |
| Super Extreme DUI | .20 + | 28-1382(A)(2) | Class 1 Misd. | 45 days |
A third DUI within 84 months, or a DUI on a suspended license or with a child under 15, becomes an aggravated (felony) DUI. See also drug DUI and DUI causing death.
Penalties for Extreme DUI in Arizona
Extreme DUIs are misdemeanors, but they carry mandatory jail that probation cannot erase, plus interlock, suspension, and thousands in fines. The reading drives the term.
Extreme
.15–.199 BAC
Super Extreme
.20+ BAC
2nd Extreme
Within 84 Months
| Charge | BAC | Minimum Jail | Interlock | Fines & Assessments* |
|---|---|---|---|---|
| First Extreme DUI | .15–.199 | 30 days | 12 months | ~$2,750+ |
| First Super Extreme DUI | .20+ | 45 days | 18 months | ~$3,240+ |
| Second Extreme DUI (84 mo) | .15–.199 | 120 days | 12–18 months | ~$3,740+ |
| Second Super Extreme DUI (84 mo) | .20+ | 180 days | 18 months | ~$4,640+ |
*Fines and assessments are approximate and change over time. All extreme DUIs also carry a 90-day license suspension and mandatory alcohol screening and treatment.
⚠ The Jail Time Is Mandatory, Until You Beat the Number
An extreme DUI’s minimum jail term cannot simply be waived by the judge once you are convicted at that level. That is why the time to fight is before a plea, by attacking the stop and the test. If the reliable reading drops below .15, the charge, and the mandatory 30 days, drop with it.
Collateral Consequences
Beyond jail, an extreme DUI brings a criminal record, a certified ignition interlock in your vehicle, sharply higher insurance (SR-22), a 90-day license suspension, mandatory alcohol screening and treatment, and problems for commercial drivers (CDL), professional licenses, employment, and immigration for non-citizens. A prior extreme DUI also counts toward a future felony.
Common Defenses in Arizona Extreme DUI Cases
An extreme DUI rises or falls on a number. Attack the stop, attack the test, and attack the timing, and the extreme charge can collapse to a standard DUI or disappear.
Attacking the Stop & Arrest
No Reasonable Suspicion for the Stop. If police lacked a lawful reason to pull you over, the stop is unconstitutional and the breath or blood result can be suppressed.
No Probable Cause to Arrest. Field sobriety tests are subjective and frequently administered incorrectly. Without valid probable cause, the arrest and the test can be thrown out.
No Actual Physical Control. Sitting in a parked car is not always “driving.” Where you were not in actual physical control, there is no DUI to call extreme.
Improper Warrant or Refusal Process. Blood drawn without a valid warrant or consent, or admin-per-se violations, can lead to suppression.
Attacking the Number
Margin of Error. Every test has a known uncertainty. Applying the lab’s own margin can drop a .15 below the extreme threshold, or a .20 below super extreme.
Breath-Machine Errors. Calibration lapses, the 15-minute observation, mouth alcohol, GERD, and radio interference all produce false highs on the Intoxilyzer.
Blood-Draw & Chain-of-Custody Problems. An improper draw, unqualified phlebotomist, fermentation, or a broken chain of custody can make the blood result inadmissible.
Rising BAC. Alcohol absorbs over time. Your level may have been below the threshold while driving and only crossed it by the time of the test, which is what the law actually requires the State to prove.
Medical Conditions & Diet. Acid reflux, diabetes, and low-carb diets can all skew a breath reading upward, independent of how much you drank.
After reviewing your case, we will explain which defenses apply and the best path forward.
CALL 623-321-4699The Experts We Bring to the Table
An extreme DUI is a science case. The State leans on a breath machine and a crime lab; we answer with specialists who challenge that science line by line.
Forensic Toxicologists
BAC & Absorption
Independently review the blood and breath results, the absorption curve, and whether the alleged number reflects your true level at the time of driving.
Breath-Test Analysts
Intoxilyzer & Calibration
Examine the machine’s calibration and maintenance logs and the 15-minute observation, exposing mouth alcohol, radio interference, and operator error that inflate readings.
Blood & Lab Experts
Gas Chromatography
Audit the blood draw, storage, fermentation risk, lab protocol, and reported uncertainty, where applying the margin of error can drop the reading below the threshold.
Medical Experts
GERD, Diabetes & Diet
Explain how acid reflux, diabetes, and low-carb diets can push a breath reading upward, independent of how much alcohol was actually consumed.
Field Sobriety Experts
NHTSA Protocol
Evaluate whether the standardized field sobriety tests were administered and scored correctly, and whether the ‘clues’ really show impairment.
Records & Discovery Specialists
Maintenance & Logs
Pull the full calibration history, repair records, and discovery the State would rather not produce, the paper trail that often reveals an unreliable machine.
What to Do After an Extreme DUI Arrest
The steps you take right after an extreme DUI arrest can decide whether the number, and the mandatory jail, hold up.
Say Nothing Beyond the Basics
Provide your license, registration, and insurance, then politely decline to answer questions and ask for a lawyer. Do not estimate how much you drank.
Act Fast on Your License
An extreme DUI triggers a separate MVD suspension with a short deadline to request a hearing. Missing it can cost you your license before the criminal case is even resolved.
Write Down the Timeline
Note when you last drank, when you were stopped, and when you were tested. The gap between driving and testing is central to a rising-BAC defense.
Preserve Everything
Keep the citation, release paperwork, and any receipts that establish timing. Do not discard anything connected to the night of the arrest.
Do Not Post on Social Media
Photos and check-ins from that night are evidence. Set your accounts to private and post nothing about the arrest.
Call Tamou Law Group at 623-321-4699
The sooner we are involved, the more we can do, demanding the machine’s records, protecting your license, and attacking the test before a plea locks in mandatory jail. Available 24/7.
Mitigation: Shaping the Outcome
Even where the reading holds, mitigation can reduce jail, protect your job, and keep the long-term consequences manageable.
We build mitigation packages that include early voluntary alcohol screening and treatment, proactive interlock installation, a clean post-arrest record, employment and family ties, and a proportionality review of comparable Arizona extreme DUI outcomes. Presented early, mitigation gives prosecutors and the court a reason to favor work-release, home detention, or the low end of the range, and it shows you took the matter seriously from day one.
The Early-Case Window
The period right after an extreme DUI arrest is when the test evidence is most vulnerable, and most worth fighting.
Before a plea is entered, we can protect your license at the MVD, subpoena the breath machine’s calibration and maintenance history, demand the blood and lab records, and present the prosecutor with the weaknesses in the number, sometimes the difference between a mandatory-jail extreme DUI and a reduced standard DUI. The sooner Michael Tamou is involved, the more leverage we have.

Attacking the Number That Drives the Whole CaseA Proven Defense Process for Arizona Extreme DUI Cases
- Challenge the Stop & the Arrest
- Attack the Breath or Blood Test
- Reduce or Dismiss the Charge
An extreme DUI is not about how you drove, it is about a number. The State alleges your alcohol concentration was .15 or higher and lets that number trigger mandatory jail. That makes the breath or blood test the entire case, and the test is exactly where these cases are won or lost.
When you work with Tamou Law Group, you get a team that includes former prosecutors and law enforcement officers who have built DUI cases. We bring in our own forensic toxicologists and breath- and blood-testing analysts to expose the margin of error, calibration failures, and timing problems behind the reading.
A few hundredths of a point changes everything. Dropping a reading from .15 to .14 turns an extreme DUI into a standard DUI, and erases the mandatory 30-day jail term. We fight for every point.
Call Michael Tamou Today & Start Fighting These Charges Right Now
623-321-46991 Challenge the Stop & the Arrest
We review whether police had reasonable suspicion to stop you and probable cause to arrest. An unlawful stop can suppress everything that followed, including the breath or blood test.
2 Attack the Breath Test
Intoxilyzer machines must be calibrated and maintained, and the officer must follow a 15-minute observation. Mouth alcohol, radio interference, and operator error all inflate the reading.
3 Attack the Blood & the Margin of Error
We scrutinize the blood draw, storage, fermentation, lab protocol, and the reported uncertainty. Applying the lab’s own margin of error can pull a borderline reading below the threshold.
4 Rising BAC & Timing
Alcohol keeps absorbing after you stop driving. We show your level may have been lower behind the wheel, and that the State cannot prove an extreme reading at the time of driving.
5 Reduce, Dismiss, or Try It
We push to reduce an extreme DUI to a standard DUI, suppress the test, or take the case to trial. That readiness is what protects you from the mandatory-jail outcome.
Recent Extreme DUI Results
Every case is unique and results depend on the facts, but these examples reflect how our firm handles extreme and super extreme DUI cases across Arizona.
Extreme DUI, Breath Reading .16
Reduced to Standard DUI
By exposing a missed observation period and the machine’s margin of error, we pushed the reliable reading below .15, eliminating the mandatory 30-day jail term.

Arizona Extreme DUI FAQs
Common questions about extreme and super extreme DUI charges, penalties, and defenses in Arizona.
What is an extreme DUI in Arizona?
Extreme DUI (A.R.S. 28-1382) is a DUI with an alcohol concentration of .15 or higher within two hours of driving. A super extreme DUI is .20 or higher. Both are Class 1 misdemeanors but carry mandatory jail that a standard DUI does not.
What is the difference between extreme and super extreme DUI?
The threshold. Extreme DUI is a BAC of .15 to .199; super extreme DUI is .20 or more. A first extreme DUI carries a mandatory minimum 30 days in jail, while a first super extreme carries 45 days and a longer interlock requirement.
How much jail time does an extreme DUI carry?
A first extreme DUI carries a mandatory minimum of 30 days in jail, and a first super extreme DUI carries 45 days. A second extreme within 84 months jumps to 120 days (180 for super extreme). The minimums cannot simply be suspended once you are convicted at that level.
Is an extreme DUI a felony?
No. Extreme and super extreme DUIs are Class 1 misdemeanors. However, a third DUI within 84 months, or a DUI on a suspended license or with a child under 15, becomes an aggravated (felony) DUI with prison exposure.
Can an extreme DUI be reduced to a regular DUI?
Yes. Because the charge depends on a single number, attacking the breath or blood test, its margin of error, calibration, mouth alcohol, or timing, can pull the reliable reading below .15 and reduce the charge to a standard DUI, eliminating the mandatory 30 days.
How accurate are breath and blood tests?
Less than the State suggests. Breath machines require careful calibration and a 15-minute observation, and conditions like acid reflux, diabetes, and radio interference skew them. Blood results depend on proper draw, storage, and lab work. Every test also has a margin of error.
What is the rising BAC defense?
Alcohol keeps absorbing after you stop drinking, so your level can be higher at the test than it was behind the wheel. The State must prove your alcohol concentration was extreme within two hours of driving, and the timing often does not support that.
Will I lose my license for an extreme DUI?
Yes. An extreme DUI brings a 90-day license suspension and a 12- to 18-month certified ignition interlock requirement, plus a separate MVD action with a short deadline to request a hearing. We address both the criminal case and the license.
Do I have to install an ignition interlock?
For an extreme or super extreme DUI conviction, yes, a certified ignition interlock device is mandatory for 12 to 18 months after your license is reinstated. We work to minimize the duration and the overall impact.
Should I just plead guilty to an extreme DUI?
Not before a lawyer reviews the test. Once you plead, the mandatory jail and interlock are locked in. The number is frequently challengeable, and a review costs you nothing, call for a free, confidential consultation first.
Will I get a real attorney or a junior associate?
At many large firms the name on the door is a marketing figurehead and your case goes to a rotating associate. At Tamou Law Group your defense is handled by a full team of experienced attorneys, not associates, including founding attorney Michael Tamou. Call 623-321-4699, 24/7.
