Misdemeanor DUI in Arizona

Most Arizona DUI charges fall under the misdemeanor category. Even though they are not felonies, they still carry mandatory jail, fines, ignition-interlock requirements, and license consequences that can impact your job, insurance, and future.

Under Arizona law, there are four primary misdemeanor DUI classifications—each defined by the driver’s level of impairment or alcohol concentration within two hours of driving.

A.R.S. § 28-1381(A)(1) — Impairment to the Slightest Degree

This is Arizona’s broadest and most frequently charged DUI offense.
A driver can be convicted if the State proves they were “impaired to the slightest degree” by alcohol, drugs, or a combination of both, even if the BAC is below .08% or no test was taken at all.

Officers often rely on subjective signs such as:

  • Bloodshot or watery eyes
  • Odor of alcohol
  • Slurred speech
  • Poor balance during field tests

Because there is no numerical BAC threshold, these cases are highly defensible. Video footage, medical conditions, and officer training errors frequently reveal that “slight impairment” was simply officer opinion—not scientific fact.

A.R.S. § 28-1381(A)(2) — DUI With a BAC of 0.08% or Greater

This is the “per se” DUI law. A driver is presumed impaired if a valid chemical test shows a BAC of 0.08% or higher within two hours of driving.
The State must prove three things:

  • The BAC test was taken within two hours of actual driving.
  • The testing instrument was properly calibrated and maintained.
  • The sample was collected, stored, and analyzed correctly.

Even with a BAC above .08, defenses exist—chain-of-custody breaks, contamination, medical conditions, or rising-BAC arguments (where the level increased after driving but before testing).

Conviction under § 28-1381(A)(1) or (A)(2) is a Class 1 misdemeanor, carrying:

  • 10 days jail (9 suspended with treatment)
  • Roughly $1,500 in fines and surcharges
  • 90-day license suspension
  • 12-month ignition interlock device

A.R.S. § 28-1382(A)(1) — “Extreme DUI” (BAC ≥ 0.15% but < 0.20%)

An “Extreme DUI” applies when a driver’s BAC is 0.15% or higher but less than 0.20%.
Penalties increase dramatically because the State presumes higher impairment and greater public risk.

Mandatory minimums include:

  • 30 days in jail (21 days suspended with treatment)
  • Fines around $2,500 – $3,000
  • 90-day license suspension
  • 12–18-month ignition interlock requirement

Even at these levels, results can be challenged by questioning calibration, blood storage, or sample integrity—issues Jeremy Huss routinely exposes through cross-examination of crime-lab personnel.

A.R.S. § 28-1382(A)(2) — “Super Extreme DUI” (BAC ≥ 0.20%)

A “Super Extreme” DUI applies when the BAC is 0.20% or greater within two hours of driving.
This charge brings the harshest misdemeanor penalties allowed under Arizona law:

  • 45 days in jail (31 suspended with treatment)
  • Minimum $3,000 + fines and surcharges
  • 90-day suspension (admin per se, first offense)
  • 18–24 months of ignition interlock
  • Mandatory alcohol screening and counseling

Despite these severe penalties, laboratory and procedural errors remain common. Testing devices often over-report high BACs when mouth alcohol, improper observation periods, or residual interference exist.

Defending Misdemeanor DUI Charges

Whether your case involves “slight impairment” or a “super-extreme” BAC, the core of the defense is the same—challenge the science, the procedure, and the officer’s judgment.
Jeremy Huss has used his prosecutorial training to reveal:

  • Improper stops without reasonable suspicion
  • Poorly administered field tests
  • Invalid breath-machine calibration
  • Blood-draw contamination or mishandling

Every element must be proven beyond a reasonable doubt, and Arizona’s strict statutes leave no room for shortcuts.

Even a misdemeanor DUI creates a permanent criminal record and mandatory penalties.
The difference between conviction and dismissal often comes down to how aggressively your attorney challenges the evidence.

Actual Physical Control

You can be charged even if the car wasn’t moving. This is the Actual Physical Control. A person sleeping in a vehicle, while in the driver’s seat, and with the car running, will almost undoubtedly be arrested and even convicted. The issue with actual physical control is how quickly the driver can put the car into motion. The best practice, if you plan to sleep in your vehicle after a few drinks, is to get into the back seat. Even if the car is running, a person sleeping in the backseat is not likely in a position to immediately put the car into motion.

By driving in Arizona, you consent to chemical testing after lawful arrest. Refusing to take a chemical test triggers an MVD suspension — it is essential to submit to the chemical test. Still, it is also vital to refuse roadside portable breath tests and field sobriety tests. It is also important not to answer any questions and provide no information other than (1) your name; (2) your identification; (3) your insurance; and (4) your registration. Politely decline to answer any additional questions. More information on what to do during a DUI investigation can be found at:
👉 What to Do During a DUI Investigation

The DUI Process from Stop to Courtroom

Traffic Stop — Officers must have reasonable suspicion. If not, evidence can be suppressed. Once the officer has reasonable suspicion, you are detained and MUST provide your actual name and identification.

Field Sobriety Tests — These tests are voluntary and highly subjective. Declining them protects your rights and prevents gifting subjective “evidence” to the State.

Arrest and TestingBlood and breath tests require strict calibration and chain-of-custody compliance.

Release and MVD Notice — The officer issues an Administrative Per Se or Implied Consent Order and may seize your driver’s license. From that moment, you have 30 days to request a hearing or summary review with MVD. The government cannot deprive you of certain things without having due process and that is what the MVD hearing is. Filing on time stays the suspension until the hearing officer issues a decision. Do nothing and your license is suspended automatically on day 31 (A.R.S. §§ 28-1321, 28-1385). And the deadline is unforgiving. If it is missed, there are no exceptions.

Court Phases — Arraignment → pre-trial → motions → trial → possible sentencing. Skilled defense often prevents cases from proceeding to trial.

Field Sobriety and Chemical Testing Flaws

Why Choose a Former Prosecutor Arizona DUI Defense Attorney

Jeremy Huss spent 12 years training officers on these exact tests. He knows what prosecutors look for—and what they miss. This insider knowledge is critical when challenging State evidence.

Field Tests: Error rates exceed 30 percent. Uneven pavement or fatigue can mimic impairment.

Breath Tests: Intoxilyzer 8000 devices require 31-day calibration and proper temperature control. Mouth alcohol or GERD can inflate results.

Blood Tests: Labs mislabel vials or use expired preservatives; chain-of-custody breaks create reasonable doubt.

Aggravated (Felony) DUI

A DUI becomes a felony under A.R.S. § 28-1383 when:

Felony DUIs carry state-prison exposure, felony records, loss of firearm rights, and immigration consequences.

Underage “Baby” DUI

Arizona’s “Baby DUI” law (A.R.S. § 4-244(34)) makes it illegal for anyone under 21 to drive with any detectable alcohol or drug in their system—essentially a 0.00 BAC limit. Unlike adult DUIs, the State doesn’t need to prove impairment or a .08 BAC. Penalties can include a two-year license suspension, counseling, probation, and ignition-interlock requirements. These cases are prosecuted aggressively and require experienced DUI defense. Learn more here:
👉 What Is Underage “Baby DUI” in Arizona

Collateral Consequences

Employment: CDL and professional licenses jeopardized.

Insurance: Rates double or triple.

Reputation: Public records indexed on Google.

Travel: Canada and some countries deny entry.

Yes, if you act within 30 days. You have 30 days to request an MVD hearing or summary review. A timely request stays the suspension until the hearing decision. Do nothing and the suspension starts automatically on day 31.
How long do I have to request the MVD hearing?
Exactly 30 days from the notice date. Miss the deadline and your license is suspended by law on day 31.
Will I go to jail for a first offense?
Yes, but most first-time defendants serve little or no jail if they complete treatment and install interlock.

Absolutely. Low-BAC cases are often defensible because they rely on subjective opinion, not science.
