DUI Laws and Penalties in Arizona

Arizona DUI laws

Each State in the United States is given the authority to write their own laws on Driving Under the Influence of alcohol, or better known as DUI. Within this article, we will explore the different DUI laws within the specific State of Arizona, including penalties. To begin with, there is what is known as a "Lookback Period" of seven years prior to the current DUI you are facing, any DUI's you may have are included in the relevancy of sentencing you are currently facing. This is also known as a "washout" period. 

What constitutes a high BAC for a DUI in Arizona?

  • Under 21: .00% (Arizona has a zero tolerance)
  • 21 or Older: .08%
  • Commercial: .04%

There is never an acceptable time to drink and drive, as your vision, responses, along with your mental capacticy to make quick and important decisions and judgments, are severely hindered and are not capable of bouncing back to what you are able to perform without alcohol in your system. Each person is different, and their tolerance level for alcohol is severely unpredictable making it impossible to say how many drinks are "normal" or not. This is what requires law enforcement to perform chemical testing on suspected DUI offenders. If you are pulled over and are requested to take a chemical test in order to determine your BAC, or Blood Alcohol Content, Arizona has an implied consent law. This means that if you refuse to submit to a chemical test you will be subject to a fine and automatic license suspension. For refusal to take the chemical test, the penalties are a follows: 

  • First Offense: 1 year suspension of license
  • Second Offense: 2 year suspension of license
  • Third Offense: 2 year suspension of license
