Why Mesa DUI Defendants Choose Gordon Thompson

There is no shortage of attorneys in the Phoenix metro area who handle DUI cases. What separates effective DUI defense from ineffective representation comes down to a handful of factors that directly affect your outcome.

47 Years of Courtroom Experience in Maricopa County

Gordon Thompson has been handling DUI and criminal defense cases in Arizona since 1979 — appearing in Mesa Municipal Court, Maricopa County Superior Court, and courts across the state for nearly five decades. That depth of local experience means he knows the courts, the prosecutors, and the procedures that directly affect how your case unfolds. Courthouse familiarity is not a marketing claim — it is a practical advantage that shows up in negotiation and at trial.

47 Years of Challenging DUI Evidence

A DUI charge is only as strong as the evidence behind it — and that evidence is often more challengeable than defendants realize. Gordon Thompson scrutinizes every aspect of a case, including:

• The traffic stop itself — Was there genuine reasonable suspicion? An unlawful stop can make all subsequent evidence inadmissible.
• Field sobriety test administration — These tests have strict protocols. Deviation from those protocols can undermine the results.
• Breath test calibration and maintenance records — Breathalyzers must be properly calibrated and serviced. Records are obtainable and reviewable.
• Blood draw chain of custody — Blood evidence must be handled according to exacting protocols from draw to lab analysis. Breaks in the chain can invalidate results.
• Dashcam and body camera footage — Video evidence frequently tells a different story than the police report.

Protecting Your Driver’s License from Day One

Most people do not realize that a DUI arrest in Arizona triggers two separate legal proceedings: the criminal case in court, and an administrative license suspension proceeding with the Arizona MVD. The MVD process moves faster and has a hard 30-day deadline to request a hearing. Miss it and your license is suspended automatically — even if you are ultimately found not guilty in court. Gordon Thompson handles both proceedings simultaneously for every Mesa DUI client.

Limiting the Impact on Your Job and Family

A DUI arrest does not just threaten your freedom and your license — it threatens your livelihood. Multiple court appearances, counseling requirements, and MVD hearings can interfere with work schedules. Gordon Thompson works to consolidate and minimize required appearances wherever the law allows, and anticipates downstream consequences — to professional licenses, security clearances, employment background checks, and insurance rates — that many attorneys overlook entirely.

What Happens After a DUI Arrest in Mesa: Step by Step

Understanding the sequence of events helps you avoid costly mistakes and gives your attorney the best chance to build a strong defense.

Step 1 — The Traffic Stop and Arrest. A Mesa Police officer stops your vehicle based on observed traffic violations or erratic driving. If impairment is suspected, field sobriety tests are requested, followed by a breath or blood test under Arizona’s implied consent law. Refusing the chemical test triggers an automatic license suspension and the refusal itself can be used against you at trial.

Step 2 — Booking and Release. You are transported to a Mesa Police facility, booked, and typically released. You will receive paperwork related to your license — this is the document that starts the 30-day MVD clock.

Step 3 — MVD Hearing Request (within 30 business days). This is the step most people miss. Gordon Thompson files this immediately on every client’s behalf to preserve your right to contest the administrative suspension.

Step 4 — Arraignment at Mesa Municipal Court. Your first court appearance, where charges are formally read and you enter a plea. At this stage, the court is required by law to inform you of your right to request a jury trial. Gordon Thompson appears at arraignment on your behalf in most cases, minimizing what you personally must attend.

Step 5 — Pre-Trial Investigation and Motions. This is where real defense work happens. Evidence is reviewed, motions to suppress may be filed, and the prosecution’s case is tested. Many cases are resolved favorably at this stage — before trial ever begins.

Step 6 — Negotiation, Trial, or Plea. Depending on the evidence and your goals, your case may resolve through a negotiated reduction or dismissal, a not-guilty verdict at trial, or — if conviction is unavoidable — the most favorable possible sentencing outcome.

Arizona DUI Law Explained: Penalties for First & Second Offense Under A.R.S. § 28-1381

If you or someone you care about has been stopped or arrested for DUI in Arizona, one of the first things you need to understand is what the law actually says — and what it means for you. This guide explains Arizona’s primary DUI statute, A.R.S. § 28-1381, in plain language, including exactly what makes a DUI unlawful, what the courts presume about your sobriety, and what penalties you face for a first or second conviction.

Arizona has some of the strictest DUI laws in the country. Understanding your exposure under the law is the first step toward making informed decisions about your case.

What Is A.R.S. § 28-1381? Arizona’s Core DUI Statute

Arizona Revised Statutes § 28-1381 is the foundation of Arizona DUI law. It defines the circumstances under which it is unlawful to drive — or even to simply be in control of — a vehicle while impaired. The law covers not just alcohol but also drugs, vapor-releasing substances, and any combination thereof. The statute applies statewide, meaning it governs DUI arrests and prosecutions throughout Arizona, including in Maricopa County cities such as Phoenix, Scottsdale, Tempe, Mesa, Chandler, Glendale, and beyond.

When Is Driving (or Being in a Vehicle) Unlawful Under Arizona DUI Law?

Under § 28-1381(A), a person violates Arizona DUI law under any of the following five circumstances:

1. Impaired to the Slightest Degree

It is unlawful to drive or be in actual physical control of a vehicle while under the influence of intoxicating liquor, any drug, a vapor-releasing substance containing a toxic substance, or any combination of these — if the person is impaired to the slightest degree. This is arguably the broadest provision in Arizona DUI law. You do not need a BAC of 0.08 or higher to be charged under this subsection. If the prosecution can show any measurable impairment, a charge is possible even at low BAC levels.

2. BAC of 0.08 or More Within Two Hours of Driving

It is unlawful to have a blood alcohol concentration (BAC) of 0.08 or more within two hours of driving or being in actual physical control of the vehicle, where the alcohol was consumed before or while driving.

3. Drugs or Metabolites in the Body

It is unlawful to drive while any drug defined in A.R.S. § 13-3401 — or its metabolite — is present in the person’s body. This includes many controlled substances. Note: a valid prescription may be a defense under certain circumstances (see below).

4. Commercial Drivers: BAC of 0.04 or More

For drivers of commercial motor vehicles requiring a commercial driver license (CDL), the legal limit is cut in half — 0.04 BAC or more is unlawful.

5. Rideshare and For-Hire Drivers: BAC of 0.04 or More

Drivers operating vehicles for hire — including transportation network company (TNC) drivers such as those working for rideshare platforms — are also held to the lower 0.04 BAC standard while providing those services.

Prescription Drug Defense and Its Limits

Under § 28-1381(D), a person who uses a drug as prescribed by a licensed medical practitioner authorized to prescribe it is not guilty of violating the “drugs in the body” provision (subsection A, paragraph 3). However, this defense does not apply to the “impaired to the slightest degree” charge under paragraph 1. In other words, a valid prescription does not automatically insulate you from a DUI charge if you are actually impaired.

Alcohol Level Presumptions at Trial

Arizona law establishes three evidentiary presumptions based on a defendant’s BAC reading within two hours of driving (§ 28-1381(G)). These apply in most DUI trials except those involving commercial vehicles or for-hire drivers:

These are rebuttable presumptions, not absolute rules. Other competent evidence may still be introduced regardless of BAC. An experienced DUI defense attorney can challenge the accuracy of BAC testing equipment, the circumstances of the stop, and how the test was administered.

First DUI Conviction in Arizona: Minimum and Maximum Penalties

A first-offense DUI under § 28-1381 is classified as a Class 1 misdemeanor — the most serious misdemeanor classification in Arizona.

When fines, court fees, surcharges, IID installation and monitoring costs, traffic survival school tuition, and attorney fees are added together, the real-world financial impact of a first DUI in Arizona commonly runs into the thousands of dollars.

Second DUI Conviction in Arizona Within 84 Months: Minimum and Maximum Penalties

If a person is convicted of a second DUI under § 28-1381 within 84 months (7 years) of a prior DUI conviction — including convictions under §§ 28-1382 (Extreme DUI) or 28-1383 (Aggravated DUI), or an equivalent offense from another state — the penalties increase substantially under § 28-1381(K). The 84-month window is measured from the dates of commission of the offenses, not the conviction dates.

A second DUI also triggers mandatory driver’s license revocation for one year. However, after serving 45 days of that revocation period, a person may petition for a Special Ignition Interlock Restricted Driver License — allowing limited driving privileges with a certified IID installed.

How Prior Convictions Are Counted

Under § 28-1381(E), the prosecution is required to allege all prior DUI convictions occurring within the past 36 months for purposes of classification and sentencing — unless there is insufficient legal or factual basis to do so. Convictions under the standard DUI statute (§ 28-1381), the Extreme DUI statute (§ 28-1382), and the Aggravated DUI statute (§ 28-1383) all count. A second conviction does not apply when both offenses arise from the same series of acts (§ 28-1381(N)).

Your Right to a Jury Trial

Many people do not realize that in a DUI case, a defendant has the right to request a jury trial. Under § 28-1381(F), at arraignment the court is required to inform the defendant of this right — and if the defendant requests a jury trial, that request must be granted. A jury trial may be a critical strategic option in your case, particularly where the evidence is disputed or the BAC test results are challengeable.

Special Situations: Serious Injury or Death, Drug DUI, and Rideshare Drivers

Collision Resulting in Serious Injury or Death: If a DUI involved a collision resulting in serious physical injury or death (as identified in a written accident report), the prosecution must be commenced within two years of actual discovery of the offense — or the date when discovery should have occurred with reasonable diligence (§ 28-1381(Q)). Drug DUI: If the DUI involves drugs rather than alcohol, a court may still order ignition interlock device installation, but it is not automatically required by the department in the same way it is for alcohol-related convictions. The standard for a drug DUI is the presence of any proscribed drug or its metabolite in the body — not impairment alone (subject to the prescription defense discussed above). Rideshare and For-Hire Drivers: These drivers are held to stricter standards under Arizona law. A BAC of 0.04 — half the standard limit — is sufficient for a DUI charge when the driver is actively providing transportation services.

Frequently Asked Questions About Arizona DUI Law

Can I be arrested for DUI if I was just sitting in a parked car?

Yes. Arizona’s “actual physical control” standard means you can be charged with DUI even without actively driving. Courts evaluate factors such as engine status, key position, and the driver’s location in the vehicle.

What if I have a prescription for the drug in my system?

A valid prescription is a defense to the “drugs in the body” provision (§ 28-1381(A)(3)), but not to the “impaired to the slightest degree” charge (§ 28-1381(A)(1)). If a prescribed medication caused any measurable impairment, you may still face charges.

Does marijuana use count as a DUI in Arizona?

This is an evolving area of Arizona law. While marijuana is legal for adult use in Arizona, driving while impaired by marijuana remains unlawful. The presence of THC metabolites in the blood following legal consumption may implicate § 28-1381(A)(3) depending on the circumstances and relevant case law developments.

What happens if I refuse a breath or blood test?

Refusing a chemical test triggers administrative consequences under Arizona’s implied consent law, including automatic license suspension — separate from any criminal DUI charges. Refusal can also be used as evidence against you at trial.

Are there enhanced penalties for very high BAC levels?

Yes — those are found in separate statutes. A.R.S. § 28-1382 covers “Extreme DUI” (BAC of 0.15 or more) and “Super Extreme DUI” (BAC of 0.20 or more), which carry their own, more severe mandatory penalties.

Why the Specific Facts of Your Case Matter

The sentences described above are legal minimums and maximums under the statute. What actually happens in any individual case depends on a wide range of factors: the strength of the evidence against you, whether BAC testing was properly conducted, whether the traffic stop was lawful, the specific court and judge involved, your personal history, and how your case is presented and defended. An experienced Arizona DUI defense attorney can evaluate every one of these factors, identify weaknesses in the prosecution’s case, and pursue the best possible outcome — whether that is a dismissal, a reduced charge, a not-guilty verdict at trial, or minimized sentencing consequences if a conviction does occur.

Arizona Extreme DUI: Sentences, Penalties & What You Need to Know (ARS 28-1382)

If you or someone you care about has been arrested for an Extreme DUI anywhere in Arizona — whether in Phoenix, Scottsdale, Tempe, Mesa, Chandler, Glendale, or anywhere else in Maricopa County — it is completely normal to feel overwhelmed. The charges sound serious, and honestly, the consequences can be serious. But knowing exactly what you are facing is the first step toward making smart decisions about your case. This post walks you through what Arizona law actually says about Extreme DUI under Arizona Revised Statutes § 28-1382 — including the real minimum and maximum penalties for both a first offense and a second offense — in plain English, not legalese.

What Is an “Extreme DUI” in Arizona?

Arizona has three tiers of DUI charges. A standard DUI (ARS 28-1381) covers a BAC of 0.08 or higher. An Extreme DUI (ARS 28-1382) kicks in at a BAC of 0.15 or higher. A Super Extreme DUI also lives within this same statute at a BAC of 0.20 or higher. There is also Aggravated DUI (ARS 28-1383) for felony-level situations. Under ARS 28-1382, you can be charged with Extreme DUI if your blood alcohol concentration is measured at 0.15 or higher within two hours of driving — and it does not matter whether you consumed the alcohol before you got in the car or while you were already driving. There are two sub-tiers within the Extreme DUI statute itself:

• Tier 1 (Extreme DUI): BAC of 0.15 or more but less than 0.20
• Tier 2 (Super Extreme DUI): BAC of 0.20 or more

The penalties are noticeably harsher in Tier 2, so I will break them out separately below.

First Offense Extreme DUI Penalties in Arizona

A first-offense Extreme DUI conviction in Arizona carries mandatory minimums — meaning a judge cannot go below these thresholds and there is no probation or suspended sentence unless the full jail term is served. Here is what the law requires:

Jail Time — First Offense

That ignition interlock option (found in subsection I of the statute) is one of the most important things to discuss with your attorney early in the process — it can make a significant practical difference.

Fines & Assessments — First Offense

The financial hit of an Extreme DUI goes well beyond just a fine. Here is the full picture:

• Base fine: Minimum $250 (Tier 1) or $500 (Tier 2)
• DUI Abatement Fund assessment: $250
• Prison Construction & Operations Fund assessment: $1,000
• Public Safety Equipment Fund assessment: $1,000

That puts the minimum total financial exposure at roughly $2,500 (Tier 1) or $2,750 (Tier 2) — before court costs, ignition interlock installation fees, traffic survival school fees, or attorney fees.

Other First-Offense Consequences

• Ignition interlock device: Required on every vehicle you operate (mandatory, not optional)
• Traffic Survival School: You must attend and complete an approved course
• Community restitution: A court may order this (it is discretionary on a first offense)
• Criminal classification: Class 1 misdemeanor — the most serious misdemeanor level in Arizona
• Jury trial right: The court must tell you at arraignment that you have the right to request a jury trial, and if you ask for one, it must be granted

Second Offense Extreme DUI Penalties in Arizona (Within 84 Months)

If you have a prior DUI conviction — under ARS 28-1381, 28-1382, 28-1383, or an equivalent conviction from another state — within 84 months (7 years) of the current offense date, Arizona law treats this as a second offense and the penalties increase substantially. The 84-month window is measured from the date of the offenses, not the conviction dates.

Jail Time — Second Offense

No probation or suspended sentence is available unless the entire sentence has been completed.

Fines & Assessments — Second Offense

• Base fine: Minimum $500 (Tier 1) or $1,000 (Tier 2)
• DUI Abatement Fund assessment: $250
• Prison Construction & Operations Fund assessment: $1,250
• Public Safety Equipment Fund assessment: $1,250

The minimum total financial exposure rises to approximately $3,250 (Tier 1) or $3,750 (Tier 2) on a second offense — again, before associated costs.

Other Second-Offense Consequences

• Driver’s license revocation: At least one year — not just a suspension, but a full revocation
• Ignition interlock device: Mandatory on every vehicle you operate after reinstatement
• Community restitution: At least 30 hours — mandatory, not discretionary
• Traffic Survival School: Required
• Special Ignition Interlock Restricted License: After completing 45 days of the revocation period, you may be eligible for a restricted license (section 28-1401)

Quick-Reference Summary: First vs. Second Extreme DUI Offense

Total Fines + Assessments~$2,500~$2,750~$3,250~$3,750 License IID required IID required Revoked ≥1 year + IID Revoked ≥1 year + IID Community Restitution May be ordered May be ordered≥30 hours (mandatory)≥30 hours (mandatory) Criminal Class Class 1 Misdemeanor Class 1 Misdemeanor Class 1 Misdemeanor Class 1 Misdemeanor

What Does “Maximum” Sentence Look Like?

The statute sets mandatory minimums, but it does not cap the jail time the court may impose. As a Class 1 misdemeanor in Arizona, the maximum possible jail sentence is 6 months (180 days) — which happens to align with the minimum for a second-offense Super Extreme DUI. Courts can also layer additional fines, longer ignition interlock periods, and extended community restitution on top of the statutory minimums. This is one reason why having skilled legal representation matters: the difference between a minimum sentence and a maximum sentence can be enormous.

A Note on the Prosecution Timeline

There is one lesser-known provision worth knowing: if your Extreme DUI case involves a collision that caused serious physical injury or death, prosecutors have up to two years from actual discovery of the offense to bring charges. This is longer than a typical misdemeanor window and means charges can surface well after the incident date.

Facing an Extreme DUI or DUI Charge in Mesa? Here Is What To Do.

The numbers above are daunting, but they represent what happens at conviction — not necessarily what has to happen in your case. An experienced Arizona DUI defense attorney will look at every aspect of your situation: how the stop was conducted, whether the breath or blood test was properly administered, whether the testing equipment was calibrated correctly, and much more.
