A first offense DUI in Arizona is considered a class 1 misdemeanor under Arizona Revised Statutes (ARS) 28-1381, with penalties that can include jail time, fines, and license suspension. The law requires a blood alcohol concentration (BAC) of at least 0.08% to trigger a DUI charge, with higher BAC levels resulting in more severe penalties. A first offense DUI conviction can result in a fine of up to $1,500, plus surcharges and fees, and a jail sentence of up to 6 months.
How Arizona Defines DUI and the Blood Alcohol Thresholds That Trigger It
Arizona law defines DUI as driving or being in actual physical control of a vehicle while under the influence of intoxicating liquor or drugs, with a BAC of 0.08% or higher, under ARS 28-1381(A)(1). The law also provides for enhanced penalties for extreme DUI, with a BAC of 0.15% or higher, under ARS 28-1382. Additionally, commercial drivers are subject to a lower BAC threshold of 0.04%, under ARS 28-1381(A)(3).
The BAC threshold is determined through a breath or blood test, with a margin of error of plus or minus 0.01%, under ARS 28-1381(E). If a driver’s BAC is above the threshold, they can be charged with DUI, regardless of whether they were actually impaired. The prosecution must prove that the driver’s BAC was above the threshold at the time of driving, which can be established through expert testimony and other evidence.
A driver’s BAC can be affected by various factors, including the amount of alcohol consumed, the time frame in which it was consumed, and the individual’s weight and metabolism. Under ARS 28-1381(F), a driver’s BAC can be estimated using a formula that takes into account the amount of alcohol consumed and the time frame in which it was consumed.

The Legal Process in Arizona for DUI Cases
After a DUI arrest, the driver will typically be taken into custody and booked into jail, where they will be required to post bail to be released.

Under ARS 28-1381(M), the driver has the right to a jury trial, which must be scheduled within 60 days of the arraignment.
During the pre-trial phase, the prosecution and defense will exchange evidence and negotiate a plea agreement, if possible.

If a plea agreement cannot be reached, the case will proceed to trial, where the prosecution must prove the driver’s guilt beyond a reasonable doubt.
At trial, the prosecution will present evidence, including testimony from witnesses and expert testimony regarding the driver’s BAC. The defense will also have the opportunity to present evidence and challenge the prosecution’s case. Under ARS 28-1381(O), the jury will be instructed on the law and will deliberate to reach a verdict.
If the driver is found guilty, the court will schedule a sentencing hearing, where the driver will be sentenced to a term of incarceration, fined, and subject to other penalties. Under ARS 28-1381(P), the court must also order the driver to attend a DUI education course and perform community service.

Recent Changes or Notable Issues in Arizona
In 2020, Arizona passed a law that requires all DUI offenders to install an ignition interlock device on their vehicle as a condition of reinstating their driver’s license. Under ARS 28-1381(Z), the law applies to all DUI offenders, regardless of whether they are first-time or repeat offenders. The law also requires the device to be installed for a period of at least 6 months, but no more than 2 years.
Additionally, Arizona has implemented a pilot program to test the use of vehicle impoundment as a penalty for DUI offenders. Under ARS 28-1381(AA), the program applies to repeat DUI offenders and requires the vehicle to be impounded for a period of at least 30 days. The program is designed to deter repeat offenders and to reduce the number of DUI-related crashes and fatalities on Arizona’s roads.
