ARS 28-1381 is Arizona’s primary misdemeanor DUI statute. Under ARS 28-1381, driving under the influence is defined as driving a motor vehicle while impaired by the slightest degree by alcohol or drugs. It also criminalizes having a blood alcohol content (BAC) of 0.08% or greater while driving or within 2 hours of driving. The statute also defines the penalties for first- and second-time misdemeanor DUI convictions in Arizona.

1) How does ARS 28-1381 define a DUI?

Arizona Revised Statute 28-1381 states that a person commits DUI by:

1) driving while under the influence of a drug or alcohol while impaired to the slightest degree by that substance;

2) having a BAC of a 0.08% or greater while driving or within 2 hours of driving;

3) driving with a drug defined in ARS 13-3401 or its metabolite in the person’s body; or

4) driving a commercial motor vehicle that requires a person to obtain a commercial driver license (CDL)with a BAC of 0.04% or more.

2) What are Arizona’s misdemeanor DUI penalties?

Most DUIs that occur in Arizona are class 1 misdemeanors. Any class 1 misdemeanor has a maximum jail term of 6 months and maximum fines of $2500 plus surcharges. However, unlike other class 1 misdemeanors, ARS 28-1381 also provides for mandatory minimum penalties for misdemeanor DUIs. The mandatory minimum sentence depends on whether this is the defendant’s first or second DUI within 7 years. If a person has a DUI from a state other than Arizona, that DUI conviction will still count as a prior DUI, as long as the conviction would also have been a crime had it been committed in Arizona (i.e., as long as the other state’s statute is sufficiently similar to Arizona’s DUI laws).

Second Offense90 days in jail (reducible to 30 days with completion of alcohol screening)
Minimum of $3,000 in fines
Minimum of 30 hours of community service

Arizona DUI Penalties under ARS 28-1381

Keep in mind that these are penalties for a violation of ARS 28-1381, which criminal law attorneys call a “regular DUI.” A driver with a BAC over 0.15% will be charged with an “Extreme DUI” and face harsher punishments, and a driver with a BAC over 0.20% will be charged with a “Super Extreme” DUI and face the most severe DUI penalties (with the exception of felony DUIs).

A DUI may also become an aggravated DUI, which is a felony, if any of the following is true:

  • If this is the driver’s third DUI offense in 7 years,
  • If the person’s drivers license was suspended;
  • If the driver was required to maintain an ignition interlock device;
  • If there was a child under the age of 15 in the car;
  • If the driver was on the wrong side of the road.

Felony DUIs are punished the most harshly of any type of DUI, and they are the only type of DUI that can result in a sentence in the Arizona Department of Corrections (i.e., the state prison system).

3) What if your BAC was below 0.08%?

A BAC of 0.08% is the “legal limit” in Arizona. This means that if the prosecutor can prove that you drove with a BAC of a 0.08% or more, then you can be convicted of a violation of the DUI statute under ARS 28-1381(a)(2) (“having a BAC of a 0.08% or greater while driving or within 2 hours of driving”).

But even if a driver has a BAC under the legal limit, he can still be convicted of a DUI under a different section of the DUI law. The prosecutor can still proceed under ARS 28-1381(a)(1) (“driving while under the influence of a drug or alcohol while impaired to the slightest degree by that substance”) if the prosecutor can prove actual impairment.

In such a case, however, the prosecutor has the burden of proving actual impairment. The prosecutor cannot rely on a test of the driver’s BAC alone to show that the driver was impaired. Instead, the prosecutor will often try to rely on the driver’s performance of the roadside Field Sobriety Tests (or FSTs) to try to prove impairment. But poor performance on FSTs can also be attributed to other factors besides alcohol impairment, such as a physical or medical condition, poor sleep, or balance issues. Furthermore, good performance on the FSTs can be used as evidence that the driver was not impaired.

A subsection of ARS 28-1381 also provides certain “presumptions” that a jury can use when deciding guilt or innocence in a DUI case. Under ARS 28-1381(G) the jury can presume that a person whose BAC is over a 0.08% is impaired. If the BAC is between 0.05% and 0.08% there is no presumption of impairment either way. And if the BAC is lower than a 0.05%, the jury can presume that the driver was not impaired.

4) Do you get a jury trial?

Yes, a defendant is allowed to have a jury trial in all DUI cases. In fact, a DUI is one of the most common types of jury trial in Arizona. If a defendant does not wish to have a jury trial, the defendant can also request a bench trial, which means the case is decided by a judge rather than a jury (although strategically, it will often be beneficial to the defendant to have a jury trial).

Most DUI cases, however, are resolved through negotiations between the defense attorney and the prosecutor. This can often lead to a favorable plea agreement that avoids some of the risks of trial or which pleads the case down to lesser charges. In some cases, it may also result in a dismissal of the defendant’s case, such as in instances where the defense attorney convinces the prosecutor that there is not enough evidence for the state to prove its case beyond a reasonable doubt.

5) What are the consequences for your license?

When a person is arrested for a DUI, they face two different types of legal consequences. The first are criminal consequences. This occurs when the state charges the driver with a DUI and he gets a court date in a city court or justice court. The second consequence or administrative consequences for your license, which can result in a license suspension. The suspension occurs independent on whatever happens in the driver’s criminal case, and it is also subject to a lower burden of proof, so there are less protections against the license suspension.

When a person is arrested for DUI and the police believe they have probable cause (i.e., they have reasonable grounds to believe the driver is DUI even if they can’t prove it beyond a reasonable doubt), then they will submit to the Arizona Department of Transportation (ADOT) an “admin per se” affidavit. On this affidavit they will attest to their belief that the driver was under the influence.

A driver’s license will automatically be suspended within 15 days of the DUI arrest when the police submit the admin per se affidavit. This will result in a license suspension for 90 days. After 30 days of the suspension period, the driver may be able to get a restricted license for the remaining suspension period that will allow him to drive to work and school. A second DUI can will result in a 1 year suspension of the driver’s license, but most drivers can drive after 45 days if they install an ignition interlock device on their car.

If the driver refused to provide a chemical test during the DUI arrest (either by providing a breath sample or a blood sample when requested by the police), then a driver’s license will be revoked for a 1-year period. This will occur regardless of whether the driver was over the legal limit or not. 

The automatic license suspension can be put on hold, however, if a motion is filed with ADOT for an administrative MVD hearing. The MVD hearing is difficult to win because the police do not need to prove impairment beyond a reasonable doubt. However, requesting an MVD hearing has the effect of stopping the automatic license suspension. This can have positive consequences for the driver by providing extra time to make arrangements for the license suspension rather than have it occur automatically within 15 days of the DUI arrest.
