    AZ DUI & DWI

    The state of Arizona defines driving under the influence, or DUI, as driving or operating a vehicle while mentally or physically impaired by any drug, alcohol or vapor-releasing substance.

    This includes driving a vehicle with a blood alcohol concentration, or BAC, of 0.08% for a personal vehicle and 0.04% for vehicles requiring a commercial driver license, such as buses. This can also include driving while inhibited by medications, even those which may have been prescribed by your doctor.

    The Penalties for DUI

    For a 1st conviction, you will serve at least 10 days in jail and pay at least $1,250 in fines. You'll also have to attend an alcohol education/treatment class and given community service. You will also be required to install a certified ignition interlock device on your vehicle(s).

    Penalties increase substantially with the severity of the intoxication and the frequency of DUI convictions.

    Your 2nd conviction (or subsequent convictions) will result in at least 90 days of jail time and at least $3,000 in fines, and you'll lose your license for 12 months. Community service, alcohol education courses, and an ignition interlock device will also be part of your sentence.

    Extreme DUI, or having a BAC of 0.15% or more, will result in much harsher penalties.

    Even Worse for Minors

    Arizona has adopted a zero tolerance stance with minors and drinking. If you're under 21 years old and found driving with any detectable amount of alcohol or drugs in your system, your license may be suspended and you may face additional criminal penalties.

    Ignition Interlock Devices

    As part of a program to discourage repeat offenders, Arizona law allows the MVD to require a person convicted of a DUI to install an "ignition interlock device," a vehicle-specific alcohol breath test that immobilizes the vehicle until a measured breath sample determines that that driver has not been drinking.
