What Is the Underage DUI Enforcement Landscape in Maricopa County?

Maricopa County, Arizona’s most populous county with over 4.55 million residents, encompasses the Phoenix metropolitan area and maintains a comprehensive legal infrastructure for DUI enforcement and adjudication. The county seat, Phoenix, anchors the largest share of DUI investigations and prosecutions statewide. The Maricopa County Attorney’s Office (MCAO) spearheads prosecution efforts, supported widely by the coordinated Holiday DUI Task Force, a key initiative implemented by the Governor’s Office of Highway Safety (GOHS) to address impaired driving spikes during holidays and special events.

The county is served by the Maricopa County Superior Court, which handles more serious misdemeanor and felony DUI cases, including those involving underage drivers. Additionally, 26 justice court precincts across six physical locations hear thousands of traffic and misdemeanor cases related to DUI annually. This expansive court system processes the high volume of cases generated across key cities such as Phoenix, Scottsdale, Mesa, Tempe, Chandler, and Glendale.

Our Oliverson Law office, situated 8 miles and about 15 minutes from downtown Phoenix inside Tempe at 60 E Rio Salado Parkway, Suite 900, offers direct access to relevant court locations and works closely with local prosecutors, judges, and law enforcement familiar with Maricopa County guidelines and trends.
