Arrested for Driving Under the Influence in Arizona?

Arizona enforces strict laws for driving under the influence of drugs or alcohol. In Arizona, you are prohibited from operating a motor vehicle if your blood alcohol concentration (BAC) is .08 or higher and can face severe criminal penalties, driver's license suspension, and long-term consequences if charged. If you or someone you love has been arrested for DUI, you need a Phoenix DUI lawyer from Knowles Law Firm, PLC.

If a law enforcement officer suspects you of driving under the influence, he or she has the right to pull you over and test your BAC level. This will typically be done through a field sobriety test, breath test or blood test. If your BAC is .08 or more, you will likely be arrested, taken into police custody, and charged for DUI. The following is a list of what Arizona laws consider driving under the influence:

The following is a list of what Arizona laws consider driving under the influence:

1. Operating a motor vehicle while under the influence of alcohol (to the point of impairment), any drug, any vapor-releasing substance, or any combination thereof.
2. Having a blood alcohol content (BAC) level of .08 or greater within two hours of driving or being in physical control of a motor vehicle.
3. For drivers of commercial motor vehicles, driving under the influence of alcohol with a BAC level of .04 or greater.

When facing DUI allegations, it is important to hire a knowledgeable DUI defense attorney who not only fully understands the laws and procedures in Arizona, but who can also protect your rights and defend you from the penalties you face.

DUI Process Defined

All Arizona DUI cases will result in two separate legal processes: a criminal case and an administrative hearing with the Arizona Motor Vehicle Division (MVD).

  • MVD Hearings
    MVD administrative hearings concern only your driving privileges and are separate from criminal proceedings. MVD hearings do not address whether you are guilty of committing the criminal act of driving under the influence, and will not result in any other penalties aside from driver's license suspension. After a DUI arrest, you must request an MVD hearing within 15 days or face an automatic license suspension.
  • Criminal Case
    The DUI process will also involve proceedings in a criminal court, where you will be charged for violating an Arizona law. Criminal proceedings will concerns whether you are guilty or innocent of the charge at hand and will determine which criminal penalties you will face. In some cases, you may also be able to reach agreements to reduce or dismiss charges / penalties.

Having an attorney by your side at all point during the DUI process is crucial. At Knowles Law Firm, PLC, we represent clients during both MVD hearings and criminal proceedings, and we fight aggressively on their behalves.
