What is a DUI?

DUI can also be called Driving While Intoxicated, or DWI. If you’re stopped for suspicion of DUI/DWI, a measurement of your blood alcohol concentration (BAC) will be taken. That measurement is used in determining whether or not you’ll be charged. If charged, the BAC will also determine the classification of your charge. The following list delineates the varying classifications for a DUI in Arizona.


  • Standard DUI: Driving a vehicle with a BAC of 0.08% or more, or 0.04% or more while driving a commercial vehicle. If younger than 21 years of age, any percent of BAC is labeled a standard DUI.
  • Extreme DUI: Driving with a BAC of 0.15% or higher.
  • Aggravated DUI: When DUI is committed on a suspended, revoked, or cancelled driver’s license; or, committing a 3rd DUI offense within 84 months; or, a DUI is committed while driving with a passenger or passengers who are 15 years old or younger.


    The higher the blood alcohol concentration, the harsher the penalties. When stopped on suspicion of a DUI, if you fail or refuse to take a test, your driver’s license will be suspended immediately by the DMV. That suspension can range from 12-24 months. The least charge for a DUI is a first-time standard DUI charge of ten days in jail and more than $1,000.00 in fines. The greatest DUI charge is for an aggravated DUI and can be as much as two years in prison and more than $3,000.00 in fines.
