Arizona DUI Laws and Penalties: How the Law Works in Plain Language
You were pulled over, tested, and arrested, or someone you care about was. Now you are trying to understand Arizona DUI laws and penalties, and the paperwork uses terms like extreme DUI and actual physical control. Those terms have specific meanings under Arizona law.
This post explains the statute at the center of nearly every Arizona DUI case and the main ideas built on it. It is written for drivers who have been arrested, their families, and anyone who wants to understand the rules ahead of time. It is general legal information, not advice about your own case.
What Statute Controls Arizona DUI Laws and Penalties?
Nearly every Arizona DUI case starts with A.R.S. § 28-1381. The statute describes three ways a driver can violate the law. The guide is built around this section and explains each one.
Understanding the statute first makes the rest of a DUI case easier to follow. Charges, tests, and later steps all connect back to it. When you hear a charge described, you can place it within this framework.
Families often need this background too. A shared understanding of the statute helps everyone follow the case and support the person facing charges.
Three ways to violate A.R.S. § 28-1381
How blood alcohol concentration is measured
Drug DUI, including marijuana, prescriptions, and metabolites
Actual physical control
Implied consent and test refusal
Baseline, extreme, super extreme, and aggravated DUI tiers
What Does Impaired to the Slightest Degree Mean in Arizona?
Yes. Arizona law includes being impaired to the slightest degree, which is separate from the 0.08 per se limit. That means a driver can face a DUI charge even below 0.08. Many people are surprised by this.
The 0.08 per se limit is a different way to violate the statute. The guide explains how the two work, and how blood alcohol concentration is measured. Knowing which theory applies to a charge helps you understand what the case is about. It also helps you follow the evidence as the case moves forward.
How Does a Marijuana DUI in Arizona Work, Including Metabolites?
DUI is not limited to alcohol. The guide covers drug DUI involving marijuana, prescriptions, and metabolites. Each of these raises its own questions under the statute, and each can look different in the evidence.
Prescription medication can surprise people, because a lawful prescription and a DUI charge can both be part of the same story. The guide explains how drug DUI fits within A.R.S. § 28-1381 so you can understand the charge in plain terms.
Drug DUI cases can involve technical terms that are unfamiliar to most drivers. A plain explanation of those terms makes it easier to follow the evidence and the discussion about it.
Can You Get an Actual Physical Control DUI in Arizona Without Driving?
You do not have to be driving to face a DUI charge in Arizona. A charge can be based on actual physical control of a vehicle. This idea catches many people off guard.
The guide explains why actual physical control matters and how it fits into the DUI statute. Understanding it helps explain charges that arise when a vehicle was not moving.
Many drivers assume that pulling over or sitting in a parked car ends the risk of a DUI charge. Actual physical control is the reason that assumption can be wrong. The guide explains the idea so you can understand how it may apply.
What Happens When Refusing a Breathalyzer in Arizona Under Implied Consent?
Arizona has an implied consent law. Refusing a test carries its own consequences, separate from the DUI charge itself. The guide explains how implied consent works and what refusal can mean.
Testing questions often come up in the stressful moments of a traffic stop. Understanding implied consent ahead of time can help you make sense of what happened afterward. It also helps you ask focused questions later, when the details of the stop are being reviewed and your memory of events matters.

How Do the Extreme, Super Extreme and Aggravated DUI Tiers Work?
Arizona DUI is organized into tiers. The guide lays them out from baseline to extreme, super extreme, and aggravated. The tier attached to a charge helps shape how serious the case is.
License consequences can follow a DUI too. The guide explains the license consequences alongside the tiers, so you can see the full picture. Laws change, so confirm current rules before relying on any detail.
DUI cases depend on specific facts, so talk with a licensed Arizona defense attorney about your situation. The guide helps you follow the process and ask focused questions of that attorney.
