How Does ARS 28-1381 Define Arizona DUI Penalties?
Most DUI violations under ARS 28-1381 are prosecuted as class 1 misdemeanors. Criminal defense attorneys can provide you with information about how being convicted of a DUI could affect you now and in the future. Plus, they can describe the many penalties associated with DUIs in Arizona, such as:
- Jail time
- Fines
- Suspension of your driver’s license
- Installation of an ignition interlock device (IID) in your vehicle
- Mandatory drug and alcohol screening and education classes

What to Do if You Have Been Charged with an Arizona DUI Under ARS 28-1381
Hire a DUI defense attorney as soon as you can after an arrest under ARS 28-1381. Your lawyer can define ARS 28-1381 in Arizona and explain the short- and long-term implications of a DUI conviction. In addition, they may help you do the following:
- Request a hearing with the Arizona Motor Vehicle Division (MVD). You typically have 15 days from the date of your arrest to ask for an MVD hearing. If you don’t request a hearing with the MVD, your driver’s license could be suspended for 90 days or longer.
- Do not discuss your case publicly. If you post content about your case on social media or speak with the prosecutor directly, you could wind up sharing information that hurts your chances of avoiding a conviction.
- Gather evidence. Your lawyer can collect video footage of your field sobriety test (FST) and arrest, breathalyzer calibration logs, witness statements, and other forms of proof. This can help your attorney lay the foundation for your legal defense.
Your attorney could negotiate a plea deal with the prosecution before your DUI case reaches trial. If no such agreement is possible, your lawyer will make sure that you are ready for Arizona DUI court.
