DUI Defense Overview

Arizona has earned a nationwide reputation for some of the toughest DUI laws in the country. Unlike many states that treat a first-offense DUI as a relatively minor matter, Arizona imposes mandatory jail time, heavy fines, license suspension, and ignition interlock requirements even for first-time offenders. The state classifies DUI offenses into four main categories, and the penalties ratchet up significantly as you move along the scale.

Understanding what you are actually facing is the first step toward mounting an effective defense. Below, we break down each type of DUI charge under Arizona law and explain what it means for you in practical terms. If you want to go deeper on any of these categories, each section links to a dedicated page with more detailed information.
