If you’re facing a Class 4 Aggravated DUI in Arizona
Designate-to-misdemeanor (DTM) under ARS § 13-604 is the path that lets an undesignated Class 6 felony become a misdemeanor at probation discharge. The court has discretion to designate the offense as a misdemeanor at the halfway point or at completion, based on the client’s compliance record. Built-in designation hearings at sentencing are stronger than relying on a future petition because the timeline is locked in by court order from day one.
