An extreme DUI in Arizona is a charge under ARS 28-1382 triggered when a driver’s BAC reaches 0.15 or higher. Extreme DUI (0.15–0.199) carries 30 days mandatory jail; super extreme DUI (0.20+) carries 45 days. Oliverson Law DUI & Criminal Defense defends these charges across Maricopa County.

Extreme vs. Super Extreme DUI Under ARS 28-1382
Arizona’s DUI statute creates a tiered penalty structure that escalates based on the driver’s measured blood alcohol concentration. While a standard DUI under ARS 28-1381 applies at 0.08 BAC, the legislature carved out two enhanced categories under ARS 28-1382 that carry significantly harsher mandatory minimums. Understanding which tier applies to your arrest determines the baseline penalties a judge must impose and shapes the defense strategy your attorney should pursue.
Extreme DUI under ARS 28-1382(A) applies when a breath or blood test produces a BAC result between 0.15 and 0.199. This threshold sits roughly twice the legal limit and represents a substantial jump in penalty exposure compared to a standard 0.08 charge. The legislature treated this range as evidence of elevated impairment warranting mandatory jail time that cannot be suspended, deferred, or converted to probation alone. Prosecutors in Tempe Municipal Court, Scottsdale City Court, and other Maricopa County venues file extreme DUI charges based on the highest qualified test result from either breath testing on an Intoxilyzer 8000 instrument or blood analysis processed through the Arizona Department of Public Safety crime laboratory.
Super Extreme DUI under ARS 28-1382(B) triggers at a BAC of 0.20 or above. The Arizona legislature added this category to address cases where impairment levels substantially exceed the extreme threshold. Mandatory jail time jumps from 30 days to 45 consecutive days on a first offense, fines increase, and the ignition interlock requirement extends. Super extreme charges frequently involve blood draws rather than portable breath tests because officers recognize that the elevated BAC may warrant hospital transport or more precise laboratory analysis. The distinction between extreme and super extreme is not academic—it translates directly into weeks of additional mandatory incarceration and thousands of dollars in additional fines and fees.
| Category | BAC Range | Statute | Mandatory Jail (1st Offense) | Mandatory Jail (2nd Offense) |
|---|---|---|---|---|
| Standard DUI | 0.08 – 0.149 | ARS 28-1381 | 10 days (9 suspended) | 90 days (60 suspended) |
| Extreme DUI | 0.15 – 0.199 | ARS 28-1382(A) | 30 consecutive days | 120 days |
| Super Extreme DUI | 0.20+ | ARS 28-1382(B) | 45 consecutive days | 180 days |
Mandatory Penalties for Extreme DUI Convictions
Arizona’s extreme DUI penalties are mandatory minimums, meaning the sentencing judge has no discretion to reduce them below the statutory floor. Unlike standard DUI where a judge can suspend the majority of a jail sentence, ARS 28-1382 requires every day of the mandatory minimum to be served. This distinction catches many defendants off guard, particularly those who assume a first offense will result in minimal jail exposure.
Jail sentences for first-offense extreme DUI require 30 consecutive days in a county or city jail facility. Courts in Maricopa County may allow work-release or work-furlough programs through the Maricopa County Sheriff’s Office, which permits defendants to maintain employment while serving their sentence. However, the 30 days must still be completed within the facility during non-work hours. Super extreme first offenses require 45 consecutive days under the same conditions. Second offenses within the 84-month lookback period raise the mandatory jail floor to 120 days for extreme and 180 days for super extreme, with limited eligibility for home detention on the portion exceeding the minimum.
Fines and surcharges for a first-offense extreme DUI start at approximately $2,500 in base fines before mandatory surcharges are added. Arizona imposes an 83% surcharge on criminal fines plus additional assessments for the prison construction fund, probation fund, and DUI abatement fund. The total out-of-pocket for fines alone typically exceeds $3,200 for extreme DUI and $3,700 for super extreme. Second offenses roughly double the base fine amount. These figures do not include attorney fees, interlock costs, treatment program fees, or insurance premium increases.
Alcohol screening and treatment are mandatory following any extreme DUI conviction. The court orders a substance abuse screening through an approved provider, and the results determine the level of required treatment. Options range from an alcohol education program of 16 to 36 hours for lower-risk assessments to intensive outpatient treatment programs requiring multiple sessions per week over several months. Treatment costs typically run $500 to $2,500 depending on the assessed intervention level. The court monitors compliance and can revoke probation for failure to complete the assigned program.
Community service requirements accompany most extreme DUI sentences. Courts in Tempe, Scottsdale, and other Maricopa County jurisdictions commonly order 30 to 90 hours of community restitution, which must be completed through a court-approved organization within the probation period. Failure to complete the hours can result in probation violation proceedings and additional jail time.

License Suspension and Ignition Interlock Requirements
An extreme DUI arrest triggers two separate license suspension tracks that run concurrently. The administrative suspension begins at the time of arrest through ADOT’s Motor Vehicle Division, while the conviction-based suspension follows the court case. Missing the administrative hearing deadline creates a suspension that applies regardless of whether you win the criminal case.
The administrative suspension under ARS 28-1321 activates when a driver either fails or refuses a chemical test. Arizona’s implied-consent law gives you exactly 15 days from the date of arrest to request an Executive Hearing Office hearing with ADOT. If you fail to request this hearing within the 15-day window, your license is automatically suspended for 90 days with no restricted driving privileges available for the first 30 days. Requesting the hearing preserves your driving privileges until ADOT issues a decision. Many defendants miss this deadline because they focus on the criminal case and do not realize the administrative process operates on its own timeline.
Conviction-based suspension adds a separate license action after the court enters a guilty finding. For a first-offense extreme DUI, expect a 90-day suspension with eligibility for a restricted license after the initial 30-day hard suspension. The restricted license permits driving to work, school, court-ordered appointments, and medical treatment, but requires the ignition interlock device to be installed before restricted privileges are granted.
Ignition interlock device requirements for extreme DUI convictions mandate installation on every vehicle the convicted person operates. The device requires a breath sample below a preset BAC threshold before the engine will start, plus random rolling retests while driving. First-offense extreme DUI carries a minimum 12-month interlock requirement, while super extreme and second offenses extend the period to 18 to 24 months. Installation costs run $75 to $150 through an ADOT-approved provider, with monthly calibration and data download fees of $60 to $100. Over a 12-month period, total interlock costs frequently exceed $1,500. Any violation logged by the device, including a failed startup test, a missed rolling retest, or evidence of tampering, is reported to the court and can trigger probation violation proceedings.
Defense Strategies for Challenging Extreme DUI Charges
Because extreme DUI penalties are mandatory upon conviction, the defense must focus on preventing a conviction or reducing the charge to standard DUI where the judge has sentencing discretion. Several technical and constitutional challenges apply specifically to the elevated BAC evidence that distinguishes extreme DUI from standard DUI.
Challenge the Blood Draw Procedure
Arizona law enforcement commonly draws blood after extreme DUI arrests, either at the scene or at a medical facility. The U.S. Supreme Court decision in Missouri v. McNeely (2013) and the Arizona Supreme Court ruling in State v. Butler, 232 Ariz. 84 (2013), established that warrantless blood draws require either valid consent or exigent circumstances. If officers drew your blood without a warrant or voluntary consent, a suppression motion under the Fourth Amendment can exclude the BAC result entirely, collapsing the extreme DUI charge.
Contest Breath Test Accuracy on the Intoxilyzer 8000
Arizona uses the CMI Intoxilyzer 8000 for evidentiary breath testing. Defense challenges target the instrument’s calibration records, the 15-minute continuous observation period required before testing, the operator’s certification, and whether mouth alcohol from recent belching, acid reflux, or dental work produced a falsely elevated reading. If the breath result placed you at 0.15 or above but independent blood retesting or retrograde extrapolation analysis shows a lower BAC, the extreme DUI charge may not survive scrutiny.
Investigate Arizona DPS Crime Laboratory Handling
Blood samples collected during DUI arrests are typically processed by the Arizona Department of Public Safety forensic laboratory. Defense attorneys can subpoena chain-of-custody documentation, storage temperature logs, and analyst qualifications. Contamination during collection, improper use of anticoagulant or preservative in the blood vial, or delays in refrigerated storage can produce fermentation artifacts that artificially elevate BAC readings. Laboratory backlogs at the DPS facility have historically created chain-of-custody gaps that experienced extreme DUI lawyers exploit in suppression motions.
Request Independent Blood Retesting
Arizona law entitles defendants to have their blood sample independently retested by a private laboratory. If the DPS lab reported a BAC of 0.15 or above but independent retesting produces a result below that threshold, the defense has strong grounds to argue the extreme DUI charge should be reduced to standard DUI under ARS 28-1381. The retesting must be requested promptly because blood samples degrade over time, and delays can compromise the evidentiary value of a lower independent result.
Retrograde extrapolation challenges apply when there is a significant delay between the traffic stop and the chemical test. BAC rises and falls over time, and a reading taken 60 to 90 minutes after the stop may not accurately reflect the BAC at the time of driving. Expert toxicologists can calculate whether the defendant’s BAC was actually at or above 0.15 at the time of operation rather than at the time of testing. If retrograde analysis places the BAC below the extreme threshold at the relevant time, the enhanced charge fails.
Plea negotiations and charge reduction remain possible even in extreme DUI cases, particularly in Tempe Municipal Court and Scottsdale City Court where evidentiary weaknesses may motivate the prosecution to offer an amended charge. A reduction from extreme DUI to standard DUI under ARS 28-1381 eliminates the mandatory 30-day consecutive jail requirement and gives the judge discretion to suspend most of the sentence. Securing that reduction depends on documented evidentiary problems that the defense identifies through discovery review, expert consultation, and motion practice.
Why Oliverson Law Handles Extreme DUI Cases Differently
Extreme DUI defense requires an attorney who understands chemical testing science, mandatory sentencing structures, and the procedural details that vary across Maricopa County courts. Oliverson Law DUI & Criminal Defense brings a depth of courtroom perspective that few Arizona firms can match because its attorneys have operated on every side of the criminal justice system.
Founding attorney Derek Oliverson served as a police officer in Henderson, Nevada, where he administered field sobriety tests and processed DUI arrests. He then moved to prosecution, handling criminal cases in Mohave County, Arizona. He later presided as a judge at Page Magistrate Court and Glendale City Court, where he sentenced defendants on DUI cases and evaluated the evidentiary motions that defense attorneys filed before him. That 17-year arc across law enforcement, prosecution, and the bench gives him direct insight into how officers write DUI reports, how prosecutors evaluate the strength of extreme DUI charges, and what judges consider when ruling on suppression motions and sentencing.
Attorney David Tangren served as a prosecutor with the Pima County Attorney’s Office before joining the firm. His felony trial experience strengthens the team’s handling of cases that may escalate from extreme DUI to aggravated DUI based on prior convictions, suspended license status, or the presence of a minor passenger. Together, the firm has handled over 5,000 cases and maintains a 4.9/5 rating from more than 150 client reviews.
When you face an extreme DUI charge in Tempe Municipal Court, Scottsdale City Court, or any Maricopa County venue, Oliverson Law evaluates every technical aspect of the BAC evidence, identifies suppression opportunities based on blood draw procedures and laboratory handling, and develops a defense strategy aimed at charge reduction or dismissal before mandatory minimums take effect.

Frequently Asked Questions
An Extreme DUI charge under ARS 28-1382 is triggered when a driver’s blood alcohol concentration measures at or above 0.15 but below 0.20. A BAC at or above 0.20 elevates the charge to Super Extreme DUI under the same statute, which carries even harsher mandatory penalties. Both thresholds are determined by breath or blood testing administered during a DUI stop, and the accuracy of those results is often the central issue in building a defense strategy.
A first-offense Extreme DUI under ARS 28-1382(A) carries a mandatory minimum of 30 consecutive days in jail with no eligibility for suspended sentences or probation in lieu of incarceration. A first-offense Super Extreme DUI under ARS 28-1382(B) increases that mandatory minimum to 45 consecutive days. Second offenses within 84 months raise the mandatory jail to 120 days for Extreme and 180 days for Super Extreme, though some portion may be eligible for home detention or work release depending on the court.
Reduction is possible but depends on successfully challenging the BAC evidence. If independent blood retesting shows a result below 0.15, or if the defense demonstrates contamination in sample collection, improper calibration of the Intoxilyzer 8000, or a break in the chain of custody at the Arizona DPS crime laboratory, the prosecution may agree to amend the charge to standard DUI under ARS 28-1381. Plea negotiations in courts like Tempe Municipal Court and Scottsdale City Court sometimes result in amended charges when evidentiary weaknesses are documented.
Yes. Upon conviction for Extreme DUI under ARS 28-1382, Arizona law requires installation of a certified ignition interlock device on every vehicle you operate. The mandatory interlock period is typically 12 months for a first offense and 18 to 24 months for a second offense. You must use an ADOT-approved installer, pay for installation and monthly calibration appointments, and provide proof of compliance to the court. Failure to install or tampering with the device can result in additional criminal charges and extended suspension.
Two separate suspension processes run simultaneously. The administrative suspension through ADOT begins at the time of arrest under the implied-consent law, ARS 28-1321, and you have only 15 days to request an Executive Hearing Office hearing to challenge it. A conviction-based suspension or revocation follows the court case. For a first-offense Extreme DUI, expect a 90-day license suspension with possible restricted driving privileges after 30 days. Failing to request the administrative hearing within the 15-day window results in an automatic 90-day suspension regardless of the criminal case outcome.
