The DUI Law in Arizona
In Arizona the offense is DUI, and the limit is 0.08.
Driving in Arizona is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the Motor Vehicle Division, separately from the criminal case.
For charging and sentencing, Arizona counts prior offenses within 7 years (84 months).
Who Makes DUI Arrests in Casa Grande
The Pinal County Sheriff's Office and the agency that reports for Casa Grande (filed by the FBI as Casa Grande Police Department) make the DUI arrests in and around Casa Grande.
The FBI's agency list also places one more agency in Pinal County: Central Arizona College (campus police).
Together, the six agencies in Pinal County with all twelve months of 2025 on file reported 8,957 arrests to the FBI that year, all offenses together; the FBI's count for Pinal County does not break DUI out.

The Court Case
A DUI charge from Casa Grande is heard in a Justice or Municipal Court, or the Superior Court when it is a felony; the County Attorney or, in a municipal court, the city's own prosecutor brings it.

The License Case
The court case is only half the record. The Motor Vehicle Division runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Arizona Department of Transportation Motor Vehicle Division keeps the driving record the conviction goes on.
