Arizona DUI Laws
In Arizona, you can be charged with a DUI if you are impaired to “the slightest degree” or if your Blood Alcohol Concentration (BAC) is 0.08% or higher (0.04% for commercial drivers). Drivers under 21 face a zero-tolerance policy, meaning any measurable alcohol can lead to a suspension.
Under the “Implied Consent” law, refusing a chemical test results in an automatic 12-month license suspension for a first refusal. Penalties for a standard first DUI conviction include a minimum of 10 days in jail, fines over $1,250, a 90-day license suspension, and required installation of an ignition interlock device.
