DUI in Arizona
State-specific overview · Criminal Law
Arizona enforces some of the nation's strictest DUI laws, including mandatory jail time and ignition interlock devices for all convictions.
How Arizona treats DUI
Arizona requires a minimum of 10 consecutive days in jail for a first DUI conviction, along with fines of $1,250–$2,500 and mandatory ignition interlock installation for 12 months. Your license suspension takes effect immediately and lasts 90 days minimum. Arizona's BAC threshold is 0.08% for drivers 21 and older, but the state also recognizes 'extreme DUI' at 0.15% BAC, which carries enhanced penalties. Refusing a breath or blood test triggers a one-year license revocation and counts as a separate offense.
The general definition of DUI
Driving under the influence of alcohol or drugs, a serious criminal offense.
DUI stands for Driving Under the Influence and means operating a vehicle while impaired by alcohol, drugs, or both. You can be charged with DUI even if your blood alcohol level is below the legal limit if your driving is noticeably impaired. Penalties vary by jurisdiction and whether it's a first or repeat offense, but typically include fines, license suspension, jail time, and mandatory alcohol education programs. A DUI conviction has lasting effects on insurance rates, employment, and your driving record.
