DUI’s in Arizona


DUI laws in the State of Arizona carry some of the harshest penalties in the nation. By statute, almost every DUI conviction must result in jail and, in some cases, prison. It is critical to know your rights and how to exercise them properly. If you’ve been arrested for suspicion of DUI, contact Millar Law to have a Former DUI Prosecutor on your side— 602-900-0545.

DUI Issues and Defenses


A DUI in Arizona is a severe offense, but it doesn’t mean your rights can be infringed. There are several ways an experienced criminal defense DUI attorney can defend your constitutional rights in a DUI case. The prosecutor always has the burden of proving a person “guilty beyond a reasonable doubt.” Here are a few possible defenses for DUI/DWI in Arizona:

The Reason for the Stop

Officers must have “reasonable suspicion” to detain you during a traffic stop. An officer can’t stop your vehicle just off a “hunch” of a possible DUI. If you are seen leaving a bar with a group of friends, this alone will not suffice for a valid stop. Officers also cannot make a stop based on race, gender, age, religion, or sexual preference.

The Reason for the Arrest

An officer must have “probable cause” to arrest a person for DUI. The arrest is invalid if an officer makes an arrest solely because you invoked your right to refuse Field Sobriety Tests (FSTs).

Field Sobriety Tests (FST) must be administered correctly— if a person is over 65 years old, 50 lbs. overweight, has specific injuries/disabilities, or is wearing improper footwear, the FSTs shouldn’t be done and could be invalidated. There are particular guidelines that officers must follow to use FSTs to support an arrest properly, and if these guidelines are not followed, the test may be considered compromised.

A certified officer must do HGN/eye testing. The officer also has HGN logs to verify their accuracy when performing the tests— if they have low accuracy, then the HGN test should carry much less weight.

Portable Breath Tests (PBT), a handheld device used before/after FSTs, are not permitted in court. However, they can be used to establish “probable cause” for arrest or the presence of alcohol. Do not let an officer convince you to take a PBT by saying, “this can’t be used in court, and it’s just for me to check to see where you’re at.”

You were not in “actual physical control” of the vehicle. If you were not driving your vehicle but sleeping in the car, there are grounds to challenge the “actual physical control.”

Violation of Constitutional Rights

If you are denied your right to counsel or an officer continues to ask questions after you invoke a constitutional right, evidence may be suppressed, or the entire case can be dismissed. You always have a right to remain silent, and communication with an attorney must be allowed as soon as possible. You should not only know your constitutional rights— Invoke them!

Issues with Alcohol Testing

Arizona Law requires breath and blood tests to follow strict guidelines. Breath test machines (Intoxilyzer) must be calibrated to specific standards and be used appropriately. Blood must be taken by a qualified individual and handled properly before lab testing (mixing, temperature-controlled storage, a chain of custody, sealed, etc.). The evidence may be suppressed if there are any issues with the blood draw or mishandling.

These tests are never exact— they are estimates and have errors involved with them. No measuring device can tell your BAC with 100% accuracy, not even blood tests.

Testing done at the station will only estimate your BAC at the time you were at the station, not when you were driving. The prosecutor may attempt to call an expert witness to conduct a “BAC retrograde,” but these linear regressions/extrapolations are based on averages. Every person is unique, and several factors affect these calculations— weight, tolerance, when you had your last drink, and even how much and when you ate. Retrogrades also work under the assumption that your BAC was declining from the time you were “driving” or in “actual physical control.” Depending on when you had your last beverage, your BAC could have been lower at the time of driving.

Misdemeanor DUI Laws


Underage DUI —A.R.S. § 4-244.34: Underage Driving or Physical Control While Under the Influence

It is unlawful for a person under the age of 21 to drive or be in physical control of a motor vehicle while there is any spirituous liquor in the person's body.
Note: this type of DUI is not considered a strike for Felony Aggravated DUI, but it can be used at sentencing as an aggravating factor to increase the penalty.

An Underage DUI in Arizona is the only DUI that does not come with mandatory jail time. However, one significant impact is that the person will lose their license for two years. There are circumstances where the judge may allow a restricted license, but this would have to be litigated; an experienced DUI attorney is essential to defend this type of DUI.

DUI Regular, Impaired to the Slightest Degree — A.R.S. § 28-1381(A)(1): Driving or Actual Physical Control While Under the Influence/Impaired to the Slightest Degree

It is unlawful for a person to drive or be in actual physical control of a vehicle in Arizona while under the influence of intoxicating liquor, any drug, a vapor releasing substance containing a toxic substance, or any combination of liquor, drugs or vapor releasing substances if the person is impaired to the slightest degree.

This type of DUI does not require a person have a BAC above 0.08. If you are below a 0.08 in Arizona, you can still get a DUI if you are impaired while driving.

DUI Regular, BAC 0.08 or more — A.R.S. § 28-1381(A)(2): Driving Under the Influence with Alcohol Concentration of 0.08 or more

It is unlawful for a person to drive or be in actual physical control of a vehicle in Arizona if the person has an alcohol concentration of 0.08 or more within two hours of driving or being in actual physical control of the vehicle and the alcohol concentration results from alcohol consumed either before or while driving or being in actual physical control of the vehicle.

This DUI does not require any impairment, which means you could appear perfectly sober and still be charged with a DUI if your alcohol concentration is 0.08 or more.

DUI Regular, Drugs — A.R.S. § 28-1381(A)(3): Driving Under the Influence of Any Drug or Metabolite

It is unlawful for a person to drive or be in actual physical control of a vehicle in Arizona while there is any drug defined in A.R.S. § 13-3401 or its metabolite in the person's body.

This type of DUI also does not require any impairment to be found. You can be charged with DUI Regular Drugs for having the drugs in your body and operating a vehicle.

Extreme DUI — A.R.S. § 28-1382(A)(1): Driving Under the Influence with Alcohol Concentration of 0.15 or more

It is unlawful for a person to drive or be in actual physical control of a vehicle in Arizona if the person has an alcohol concentration of 0.15 or more but less than 0.20 within two hours of driving or being in actual physical control of the vehicle and the alcohol concentration results from alcohol consumed either before or while driving or being in actual physical control of the vehicle.

Super Extreme DUI — A.R.S. § 28-1382(A)(2): Driving Under the Influence with Alcohol Concentration of 0.20 or more

It is unlawful for a person to drive or be in actual physical control of a vehicle in Arizona if the person has an alcohol concentration of 0.20 or more within two hours of driving or being in actual physical control of the vehicle and the alcohol concentration results from alcohol consumed either before or while driving or being in actual physical control of the vehicle.

This is the highest class of misdemeanor DUI in Arizona and carries the harshest penalties; see below.

CDL DUI — A.R.S. § 28-1381(A)(4): Driving Under the Influence while Operating a Commercial Motor Vehicle

It is unlawful for a person to drive or be in actual physical control of a vehicle in Arizona if the vehicle is a commercial motor vehicle that requires a person to obtain a commercial driver's license as defined in A.R.S. § 28-3001 and the person has an alcohol concentration of 0.04 or more.

A CDL DUI has a much lower BAC requirement, only 0.04, and does not require any impairment to be found. In addition, a CDL driver will lose their license to drive commercially for one year if convicted of any DUI statute, regardless of whether they were operating a commercial or personal vehicle.

Handling a DUI Stop


Don’t Drink and Drive.

First and foremost, do not get behind the wheel if you’ve had too much to drink. A taxi only costs a small amount but can save lives, your career, and keep you out of jail/prison.

Be Respectful.

Be Respectful to the officer and have documentation ready when they approach you. Getting upset and arguing will only escalate the situation and might even incentivize the officer to investigate more. Also, aimlessly searching the vehicle for documentation could be used as evidence of impairment.

Don’t Do Field Sobriety Tests or make Admissions.

Do not make any admissions or do any Field Sobriety Tests, including HGN/eye tests or Portable Breath Tests (PBT). Many people think they must do these tests and answer questions— this is incorrect! Any admission or test result will be used against you as evidence in court. Also, don’t try to talk your way out of it. You may believe you’re fooling the officer, but they are likely gathering evidence against you.

Invoke your right to an attorney as soon as possible.

Don’t Do Breath or Blood Testing.

Don’t consent to any testing if you are arrested UNLESS a warrant is served on you. The officer can use force to draw blood from you if the officer has a warrant. Fighting them can result in more charges against you, including Felony Aggravated Assault on an Officer. Contact an experienced criminal DUI defense attorney at Millar Law to guide you through the process and protect your rights. If you are arrested at the station, you must be allowed to speak with an attorney as soon as reasonably possible.

Note: Refusing “Implied Consent” Breath/Blood testing might result in a suspension of your driving privileges for one year (possibly two years if you have a prior refusal). The officer must inform you of this consequence to obtain a proper “refusal” that leads to suspension.
