Driving under the influence (DUI) is a serious offense in Arizona, with strict penalties and long-term consequences. Whether it’s your first arrest or a repeat offense, understanding DUI in Arizona and the relevant laws such as ARS 28-1383 can make a big difference in how you handle the situation. This guide explains everything you need to know—from the definition and types of DUI charges to penalties, defenses, and legal options.

What Is a DUI in Arizona?

Under Arizona law, a DUI (Driving Under the Influence) occurs when a person operates a motor vehicle while impaired by alcohol, drugs, or any other intoxicating substance. Arizona has some of the toughest DUI laws in the country, designed to discourage impaired driving and ensure road safety.

A driver can be charged with DUI if they meet any of the following conditions:

1. Their Blood Alcohol Concentration (BAC) is 0.08% or higher within two hours of driving.

2. They are impaired to the slightest degree by alcohol or drugs, even if their BAC is below the legal limit.

3. They are under the influence of drugs, including prescription medications or illegal substances.

For commercial drivers, the legal BAC limit is 0.04%, and for drivers under 21, any alcohol concentration can result in a DUI charge.

Key Arizona DUI Laws: ARS 28-1381, ARS 28-1382, and ARS 28-1383

Arizona’s DUI laws are mainly outlined in Title 28, Chapter 4, Article 3 of the Arizona Revised Statutes (ARS). The most important sections include:

1. ARS 28-1381 – Basic DUI

This law makes it illegal for any person to drive or be in actual physical control of a vehicle while:

1. Under the influence of intoxicating liquor, drugs, or a vapor-releasing substance, and

2. Impaired to the slightest degree.

A first-time offender under this statute faces a Class 1 misdemeanor.

2. ARS 28-1382 – Extreme DUI

This applies when a driver’s BAC is 0.15% or higher within two hours of driving. There are two levels:

1. Extreme DUI: BAC between 0.15% and 0.199%.

2. Super Extreme DUI: BAC of 0.20% or higher.

3. ARS 28-1383 – Aggravated DUI

The ARS 28-1383 law defines Aggravated DUI—a more serious felony offense. It applies when a person:

1. Commits a DUI while their driver’s license is suspended, revoked, or restricted.

2. Commits a third DUI within 7 years.

3. Drives under the influence with a child under 15 years old in the vehicle.

4. Refuses to install an ignition interlock device after being ordered to do so.

Aggravated DUI is classified as a Class 4 felony and carries much harsher penalties.

Penalties for DUI in Arizona

Arizona imposes strict penalties for DUI convictions. The punishment depends on the type of DUI and whether it’s a first-time or repeat offense.

1. First-Offense DUI (ARS 28-1381)

3. Felony record that can affect employment and civil rights.

4. Mandatory substance abuse screening and interlock device upon reinstatement.

License Suspension and Ignition Interlock Device

After a DUI arrest in Arizona, your driver’s license can be suspended immediately. Even before a court conviction, the Motor Vehicle Division (MVD) can impose an administrative suspension.

You may request a hearing within 15 days to contest this suspension. If convicted, you’ll need to install an ignition interlock device (IID) in your vehicle for a specified period—usually 12 months for a first DUI.

The Legal Process After a DUI Arrest

Being charged with a DUI in Arizona can be intimidating, but knowing what to expect helps you make informed decisions.

1. Arrest and Chemical Testing:
   Police will test your blood, breath, or urine for alcohol or drugs.

2. Administrative License Suspension:
   Your license can be suspended immediately unless you request an MVD hearing.

3. Criminal Court Process:
   You’ll receive a court date for your arraignment, where you can enter a plea.

4. Pretrial Hearings and Plea Negotiations:
   Your attorney may negotiate reduced charges or penalties.

5. Trial (if applicable):
   If no plea deal is reached, your case proceeds to trial.

6. Sentencing and Penalties:
   If convicted, the judge imposes penalties based on the offense type and prior record.

Common Defenses Against DUI Charges

A DUI charge doesn’t automatically mean a conviction. A skilled DUI defense lawyer can challenge the evidence and potentially get charges reduced or dismissed. Common defenses include:

1. Improper traffic stop (lack of reasonable suspicion).

2. Faulty breathalyzer or blood test results.

3. Inaccurate field sobriety tests.

4. Violation of Miranda rights.

5. Medical conditions that mimic impairment symptoms.

6. Improper police procedures.

Having an experienced attorney who understands ARS 28-1383 and other DUI statutes is essential for protecting your rights.

Long-Term Consequences of a DUI Conviction

The impact of a DUI in Arizona goes far beyond fines and jail time. Some of the lasting consequences include:

1. Higher auto insurance rates.

2. Criminal record visible to employers and landlords.

3. Difficulty obtaining professional licenses.

4. Travel restrictions, especially to countries like Canada.

5. Mandatory alcohol treatment and probation requirements.

Because an Aggravated DUI (ARS 28-1383) is a felony, it can also result in loss of certain civil rights such as voting or owning firearms until they are restored.

How a DUI Defense Lawyer Can Help

Facing a DUI charge in Arizona can feel overwhelming, but professional legal help can make a significant difference. A DUI defense lawyer can:

1. Review and challenge the evidence against you.

2. File motions to suppress illegal evidence.

3. Negotiate with prosecutors for reduced charges or lighter penalties.

4. Represent you in court hearings and MVD proceedings.

5. Help you restore your license and clean your record over time.

If you’re charged under ARS 28-1383, having experienced legal counsel is even more critical, as felony DUI cases are complex and carry severe penalties.

Preventing DUI: Stay Safe and Responsible

The best way to avoid DUI charges is through responsible choices. Here are some practical tips:

1. Plan ahead for a designated driver or ride service.

2. Avoid driving after taking prescription drugs that cause drowsiness.

3. Know your limits and allow time for alcohol to leave your system.

4. Use public transport or rideshare apps when attending social events.

Remember, prevention is always better than dealing with the consequences of a DUI conviction.
