Recent DUI Defense Results Handled by Our Arizona DUI Lawyers
Every case is unique and results depend on the facts, but these examples reflect how our firm handles serious DUI cases across Arizona.
Super Extreme DUI (.20+ BAC)
Case Dismissed
After challenging the blood draw procedure and exposing violations in the chain of custody, the court suppressed the BAC evidence and the prosecution dismissed all charges.

By challenging breathalyzer calibration records and the 15-minute observation period, the Extreme DUI charge was reduced, significantly lowering mandatory jail time and fines.

Charges Reduced to Misdemeanor
Client faced Class 4 felony aggravated DUI. After challenging the license suspension status and negotiating with the prosecution, the case was resolved as a misdemeanor with no prison time.

Standard DUI – First Offense
Plea to Non-DUI Offense

Why You Need a DUI Lawyer Immediately
Arizona consistently ranks among the states with the toughest DUI laws in the nation. Under ARS § 28-1381, even a first-offense DUI is a Class 1 misdemeanor carrying mandatory jail time — a minimum of 10 days — plus fines exceeding $1,250, mandatory ignition interlock device installation, license suspension of 90 days to one year, and mandatory alcohol screening and education. There is no diversion or deferred prosecution for DUI in Arizona — every conviction carries mandatory minimum penalties that judges cannot waive.
Beyond the criminal case, you face an administrative license suspension through the Arizona MVD that begins automatically unless you request a hearing within 15 days of your arrest. Blood evidence, breathalyzer calibration records, and officer body cam footage must be challenged early. The longer you wait to hire a DUI lawyer, the harder it becomes to preserve and challenge the evidence that will determine your case outcome.

What Clients Say About Tamou Law
DUI Charges We Defend in Arizona
Every DUI Classification Under Arizona Law — From Standard to Felony
Arizona imposes mandatory penalties for all DUI types. Higher BAC levels and aggravating circumstances mean dramatically harsher consequences. Click each charge to see penalties and how we defend it.
Standard DUI — BAC .08%+ or Impaired to the Slightest Degree
Penalty: Minimum 10 days jail.. Fines $1,500+. 90-day license suspension. Ignition interlock 6-12 months. Alcohol screening & education.
2nd offense in 84 months: 90 days jail (minimum mandatory). 1-year license revocation.
Arizona’s “impaired to the slightest degree” standard under ARS § 28-1381(A)(1) means you can be convicted even with a BAC below .08 if the State proves any alcohol impairment. Defense centers on challenging the traffic stop, field sobriety tests, BAC testing procedures, and rising BAC defense.
Extreme DUI — BAC .15%–.199%
Penalty: Minimum 30 days jail. Fines $2,500+. 90-day license suspension. Ignition interlock 12 months.
2nd offense: 120 days mandatory jail.
Extreme DUI under ARS § 28-1382(A)(1) carries dramatically higher mandatory minimums. Breathalyzer calibration errors, blood draw timing issues, and rising BAC defense are critical — a small BAC challenge can drop Extreme to Standard, cutting mandatory jail from 30 days to 1 day.
Super Extreme DUI — BAC .20% or Higher
Penalty: Minimum 45 days jail. Fines $3,000+. Ignition interlock 18 months.
2nd offense: 180 days mandatory jail.
The highest BAC tier under ARS § 28-1382(A)(2). Challenging the blood draw or breathalyzer accuracy is critical — if we can show the BAC was below .20 at the time of driving, the charge drops to Extreme or Standard with dramatically lower mandatory jail.
Drug DUI — Any Drug or Metabolite While Impaired
Penalty: Same as Standard DUI: 1-10 days jail. Fines $1,500+. 90-day license suspension.
Under ARS § 28-1381(A)(3), driving with any drug or its metabolite in your body is illegal. However, having a valid and lawful reason for the medication is a defense if it was taken as directed. The State must still prove actual impairment. We challenge toxicology results, drug recognition expert procedures, and the State’s impairment evidence.
Aggravated DUI — Class 4 Felony
Penalty: Up to 3.75 years in prison. 1-year license revocation. Felony record.
Triggers: 3rd DUI in 84 months, DUI on suspended/revoked license, DUI with child under 15, wrong-way driving while DUI, ignition interlock violation.
Aggravated DUI under ARS § 28-1383 is the most serious DUI charge in Arizona. It carries mandatory prison time, loss of civil rights, and permanent felony consequences. We fight to challenge the aggravating factor — disputing prior convictions, license status, or the circumstances — to reduce the charge to a misdemeanor.
Commercial DUI — BAC .04% (CDL Holders)
Penalty: 1-year CDL disqualification (lifetime for 2nd offense). Same criminal penalties as Standard DUI.
CDL holders face a lower BAC threshold of .04 — even when driving a personal vehicle. A single DUI can end a commercial driving career. We fight aggressively to protect CDL holders’ livelihoods through BAC challenges, testing procedure attacks, and aggressive negotiation.
DUI With Accident or Injury
Penalty: Standard DUI penalties plus potential additional charges for leaving the scene, endangerment, or assault. Aggravated DUI if serious injury.
DUI cases involving collisions are prosecuted more aggressively. We challenge the officer’s determination of fault, the field sobriety test administration, and the blood draw timing. The accident itself does not prove impairment — and the State still must establish BAC and impairment through admissible evidence.
Actual Physical Control — DUI Without Driving
Penalty: Same as Standard DUI — mandatory jail, fines, license suspension, interlock.
Arizona can charge you with DUI even if you weren’t driving. Sitting in a vehicle with keys accessible while impaired qualifies as “actual physical control.” We challenge whether you were truly in control — considering the vehicle location, engine status, key placement, and your intent to drive.
Whatever DUI charge you’re facing — call now for a free, confidential consultation.

Common Defense Strategies in Arizona DUI Cases
A strong DUI defense starts with understanding the science, the procedures, and the weaknesses in the State’s case. Our DUI lawyers evaluate every angle before deciding how to move forward.
Challenging the Traffic Stop & Arrest
Illegal Traffic Stop – Law enforcement must have reasonable suspicion to pull you over. If this standard was not met, we file a motion to suppress all evidence obtained during the stop — which can lead to your case being dismissed entirely.
Improper Field Sobriety Testing – Field sobriety tests can be unreliable, especially if administered incorrectly or under unfavorable conditions like poor lighting, uneven surfaces, or bad weather. Fatigue, nervousness, and medical conditions also affect performance. We investigate whether the officer was properly trained and certified.
Lack of Probable Cause for Arrest – Officers must have sufficient evidence of impairment beyond swerving, odor, or bloodshot eyes. If the officer didn’t have enough evidence to arrest you, we argue the arrest was unlawful — which can result in the case being dismissed.
Violation of Miranda Rights – If you were arrested and questioned without being read your Miranda rights, any statements made during interrogation may be inadmissible. This can significantly weaken the prosecution’s case.
Challenging the BAC Evidence
Faulty BAC Testing – Breathalyzer and blood tests are not perfect. If testing equipment was not properly calibrated or the test was improperly administered, the BAC results can be challenged. We request all maintenance records and evaluate whether proper procedures were followed.
Blood Sample Issues – The prosecution must prove the blood sample was properly handled and stored throughout the testing process. Any break in the chain of custody means the results may be unreliable or inadmissible. We analyze blood results and chain of custody for every possible error.
Rising BAC Defense – Your BAC may have been below .08 while driving but rose above the limit by the time testing occurred. Alcohol absorption takes time — we use expert toxicologists to demonstrate your BAC at the time of actual driving was legal.
Medical Conditions – Certain medical conditions, such as diabetes or acid reflux, can lead to falsely elevated BAC results. High levels of acetone in breath can be mistaken for alcohol by a breathalyzer. This defense can be effective when the BAC reading doesn’t match the driver’s level of impairment.
After reviewing your case, the DUI lawyers at Tamou Law Group will explain which defenses apply, how they can be presented, and whether the best path forward is dismissal, suppression, negotiation, or trial.
Arizona DUI Sentencing Framework
Arizona has some of the strictest DUI penalties in the nation with mandatory minimum jail time for every conviction — including first offenses. Understanding your exposure is the first step toward an effective defense.
Misdemeanor DUI Sentencing
1st Standard DUI (.08+) – 10 days jail (mandatory) $1,250+ fines, 90-day to 1-year license suspension, ignition interlock 6-12 months, alcohol screening & education.
1st Extreme DUI (.15+) – 30 days jail (mandatory), $2,500+ fines, 1-year license suspension, ignition interlock up to 12 months. 2nd offense: 120 days mandatory jail.
1st Super Extreme DUI (.20+) – 45 days jail (mandatory), $2,750+ fines, ignition interlock up to 18 months. 2nd offense: 180 days mandatory jail.
Felony DUI & Collateral Consequences
Aggravated DUI (Class 4 Felony) – 1 to 3.75 years in prison. Mandatory minimum 4 months for 3rd offense in 84 months. Loss of civil rights, felony record.
Insurance rate increases – A DUI conviction triggers SR-22 filing requirements and dramatically increases auto insurance premiums for 3-5 years, often doubling or tripling your rates.
Professional licensing impact – DUI convictions can disqualify you from careers in healthcare, law enforcement, education, commercial driving, and any field requiring professional licensing or security clearance.
Immigration consequences – For non-citizens, a DUI conviction — especially Aggravated DUI or DUI with drugs — can trigger deportation proceedings, denial of naturalization, or permanent inadmissibility.
Employment & career barriers – A permanent DUI on your criminal record affects background checks, CDL eligibility, military service, and professional opportunities for life.
The stakes in a DUI case are higher than most people realize. The sooner you involve a DUI lawyer, the more options you have to protect your license and your future.
MVD Hearings & License Protection — The 15-Day Deadline
Your License Will Be Automatically Suspended Unless You Act Within 15 Days
After a DUI arrest in Arizona, you will receive an Admin Per Se / Implied Consent Affidavit from the arresting officer. This document triggers an automatic license suspension — separate from your criminal case — unless you request an administrative hearing within 15 days. Missing this deadline means your license is suspended by default.
The observations on this form — “bloodshot, watery eyes,” “odor of alcohol,” “slurred speech” — are cookie-cutter phrases that officers use in nearly every DUI arrest. They are not proof of impairment. We compare the officer’s written observations against actual body cam footage to expose exaggerations and inconsistencies.
Step 1
Request MVD Hearing
File within 15 days of arrest. Tamou Law Group files this request immediately upon retention. Missing this deadline = automatic suspension.
Step 2
Challenge the Evidence
Challenge officer observations, testing procedures, implied consent advisement, and whether BAC results are reliable enough to support suspension.
Step 3
Win or Secure Restricted License
Win the hearing and overturn the suspension entirely — or secure a restricted license with interlock so you can keep driving to work and appointments.
You Have Only 15 Days to Save Your License
Don’t let the MVD suspend your driving privileges by default. Call Tamou Law Group now and we will file your MVD hearing request immediately.

Advanced DUI Science Training That Most Defense Lawyers Don’t Have
Most criminal defense firms treat DUI cases as routine. They list “DUI” alongside shoplifting and traffic tickets — but when a client walks in with a Super Extreme DUI, an Aggravated felony, or a complex drug DUI with toxicology issues, they don’t have the training to challenge the science. They accept the BAC number at face value. They don’t know how breathalyzers actually work. They can’t cross-examine a forensic toxicologist. And they’ve never attended a single DUI defense training seminar.
Don’t let hyperinflated statistics from other firms trick you. Some firms advertise “5,000+ case victories” — but those numbers include other fields of law and speeding tickets. When you ask how many of those were DUI cases where they challenged the blood draw, fought a breathalyzer result, or won at an MVD hearing, the answer is often zero.
Tamou Law Group handles criminal defense exclusively — we don’t pad our numbers with estate, family, or personal injury law.
What Makes Tamou Law Group Different
✔ National College for DUI Defense (NCDD) members — advanced training in blood testing science, breathalyzer technology, field sobriety procedures, and forensic toxicology. This is the gold standard for DUI defense training in the United States.

✔ Former prosecutors and public defenders on our team — who understand how the State builds DUI cases from the inside, how officers are trained to conduct DUI investigations, and how BAC evidence is presented to judges and juries.
✔ BAC science challengers — we request all breathalyzer maintenance records, challenge blood draw procedures, retain independent toxicologists, and cross-examine lab technicians with technical precision that most defense lawyers simply cannot match.
A Team Built for the Hardest DUI Cases
Tamou Law Group has defended some of the most complex DUI cases in Maricopa County — including Super Extreme DUI, Aggravated DUI felonies, DUI with serious injury, drug DUI, commercial driver DUI, and cases involving contested blood draws and breathalyzer challenges.

What Should I Do If I Am Arrested for DUI in Arizona?
What you do in the first 24-48 hours after a DUI arrest can determine your case outcome. You have critical deadlines — including the 15-day MVD hearing window — that require immediate action.
Critical Steps After a DUI Arrest
1Be Polite But Say Nothing – Provide your license, registration, and insurance. Beyond that, politely decline to answer questions about where you were, how much you drank, or when your last drink was. Everything you say will be used against you.
2Request an Attorney – Clearly state “I want a lawyer” before submitting to any chemical testing. Arizona’s implied consent law requires testing, but you have the right to counsel first.
3Request the MVD Hearing Within 15 Days – You must request an administrative hearing with the MVD within 15 days of your arrest or your license will be automatically suspended. A DUI lawyer can handle this immediately.
4Document Everything – Write down arrest details, officer names, badge numbers, what tests were performed, and the timeline of events while memory is fresh. This information helps build your defense.
5Call Tamou Law Group at 623-321-4699 – We provide immediate legal representation, MVD hearing requests, and aggressive DUI defense for arrests anywhere in Arizona.
6Do Not Post on Social Media – Do not post anything about your arrest, where you were drinking, or the incident online. Prosecutors actively monitor defendants’ social media accounts in DUI cases.

Arizona DUI Lawyer FAQs
These frequently asked questions explain what to expect after a DUI charge or arrest in Arizona and how Tamou Law Group can help protect your future.
What is the penalty for a first DUI in Arizona?
A first-offense DUI under ARS § 28-1381 carries a minimum of 10 days in jail (9 may be suspended upon completion of screening), fines of $1,250 or more, 90-day to 1-year license suspension, mandatory ignition interlock device for 6-12 months, and mandatory alcohol screening and education. Arizona has no diversion for DUI — every conviction carries mandatory minimums.
What is the difference between DUI, Extreme DUI, and Super Extreme DUI?
Standard DUI applies at .08+ BAC, Extreme DUI at .15+ BAC, and Super Extreme DUI at .20+ BAC. Penalties escalate at each tier: standard DUI carries 10 days minimum jail, Extreme DUI carries 30 days, and Super Extreme DUI carries 45 days. Fines, license suspension, and ignition interlock requirements also increase at each level.
What is Aggravated DUI in Arizona?
Aggravated DUI under ARS § 28-1383 is a Class 4 felony. It applies when you commit DUI while your license is suspended for a prior DUI, commit a 3rd DUI within 84 months, drive DUI with a child under 15, drive the wrong way while DUI, or violate an ignition interlock requirement. Aggravated DUI carries mandatory prison time.
Can I refuse a breathalyzer or blood test in Arizona?
Arizona has an implied consent law — by driving on Arizona roads, you consent to chemical testing when lawfully arrested for DUI. Refusing a test results in an automatic 12-month license suspension. However, a refusal can also mean the State has weaker BAC evidence. Your DUI lawyer can advise you on the best strategy for your situation.
How long do I have to request an MVD hearing?
You have only 15 days from the date of your DUI arrest to request an administrative hearing with the MVD to fight your license suspension. Missing this deadline means your license will be automatically suspended. Contact a DUI lawyer immediately to ensure this hearing is requested on time.
Can a DUI be dismissed in Arizona?
Yes. DUI cases can be dismissed or reduced through constitutional challenges (illegal traffic stop, improper arrest), suppression of BAC evidence (flawed blood draws, breathalyzer errors), procedural violations, or weakness in the State’s impairment evidence. An experienced DUI lawyer evaluates every possible avenue for dismissal.
How much does a DUI lawyer cost?
DUI defense costs vary based on charge severity, BAC level, and case complexity. Misdemeanor DUI cases typically range $2,500-$7,500 while felony Aggravated DUI defense can cost $7,500-$25,000 or more. Tamou Law Group offers affordable payment plans and free consultations. The cost of experienced representation is minimal compared to conviction consequences.
Can I get a DUI expunged in Arizona?
Arizona allows record expungement for certain charges under ARS § 13-911. Eligible cases include dismissed DUI charges, acquittals, and some completed misdemeanor convictions after waiting periods. Felony DUI convictions are generally more difficult to expunge. Tamou Law Group handles expungement cases throughout Arizona.
What is “actual physical control” DUI?
Arizona can charge you with DUI even if you weren’t driving. If you are sitting in a vehicle with the keys accessible and are impaired, you can be charged under the “actual physical control” provision. Factors include the vehicle’s location, whether the engine was running, and where the keys were. This charge carries the same penalties as a standard DUI.
Can I be charged with DUI for taking medication?
Yes. Under ARS § 28-1381(A)(3), driving with any drug or its metabolite in your body is illegal. However, having a valid reason for the medication is a defense if it was taken as directed. The prosecution must still prove actual impairment. A DUI lawyer can build a medical evidence defense to challenge drug DUI charges.
What happens if I get a DUI with a commercial driver’s license?
CDL holders face a lower BAC threshold of .04 and a mandatory 1-year CDL disqualification for a first DUI offense — even if driving a personal vehicle. A second offense means lifetime CDL disqualification. The career consequences make aggressive DUI defense critical for commercial drivers.
Why choose Tamou Law Group for DUI defense?
We provide aggressive, strategic DUI defense with a team that includes former prosecutors, public defenders, and members of the NCDD and DUIDLA. Over 1,000 cases won, fast response times, advanced DUI science training, and focused advocacy to protect your license, freedom, and record across Arizona.
