A Kingman DUI lawyer from Oliverson Law PLLC provides defense from our local office at 707 Beale Street in downtown Kingman, steps from Mohave County Superior Court and the historic Route 66 corridor. Kingman sits at the junction of I-40 and AZ-93, the primary highway connecting Phoenix to Las Vegas, making it a high-volume DUI enforcement zone. Derek Oliverson, a former Mohave County prosecutor, brings 17+ years and 5,000+ cases of experience. Call (928) 275-7344.
Kingman is the county seat of Mohave County and sits at the crossroads of Interstate 40 and AZ-93, the highway corridor that funnels traffic between Phoenix and Las Vegas. This geographic position creates a DUI enforcement landscape unlike anywhere else in Arizona. DPS troopers patrol AZ-93 heavily, particularly on Friday and Sunday evenings when weekend traffic to and from Las Vegas peaks. Drivers returning from casinos on the Nevada border face stops along the 70-mile stretch between Hoover Dam and Kingman, with arrests processed through Mohave County courts.
Within Kingman itself, the Route 66 corridor (Andy Devine Avenue and Beale Street) forms the downtown core where bars, restaurants, and the historic district generate nighttime DUI enforcement by the Kingman Police Department. The Mohave County Sheriff’s Office covers unincorporated areas surrounding Kingman, including Golden Valley, Dolan Springs, and the communities along AZ-68 toward Laughlin and Bullhead City.
Kingman also experiences enforcement spikes during Lake Havasu spring break season, when young adults travel through Kingman on I-40 and AZ-95 to reach Lake Havasu City. Multi-agency DUI task forces deploy along these corridors during March and April. Similarly, the Route 66 Fun Run car show and Mohave County Fair generate increased enforcement in and around Kingman proper.
Derek Oliverson has deep ties to Mohave County. Before founding Oliverson Law PLLC, he served as a prosecutor in the Mohave County Attorney’s Office, where he handled DUI cases in the same courthouse where he now defends clients. That prosecutorial experience in this exact jurisdiction gives him firsthand knowledge of how the Mohave County Attorney’s Office builds cases, which officers are assigned to DUI task forces, and what evidence local judges weigh most heavily.
Kingman Municipal Court handles misdemeanor DUI cases arising from Kingman Police Department arrests within city limits. The court is located in downtown Kingman, a short walk from our office at 707 Beale Street. Arraignments are typically scheduled within two to three weeks of arrest, and the court’s manageable docket allows for more individualized case attention than high-volume Maricopa County courts.
Mohave County Superior Court at 401 E Spring Street handles all felony aggravated DUI cases in the county, including arrests from Kingman, Bullhead City, Lake Havasu City, and the unincorporated communities. The Mohave County Attorney’s Office prosecutes these cases, and Derek Oliverson’s prior service in that office means he knows the prosecutors, their case evaluation standards, and the judges who preside over DUI matters.
For DPS arrests on AZ-93 between Kingman and Wickenburg, jurisdiction depends on the exact location. Stops within Mohave County process through Kingman courts, while stops south of the county line route to Yavapai County courts in Prescott. The 15-day MVD hearing deadline applies identically regardless of where the arrest occurs.

Mohave County judges apply Arizona’s statewide DUI sentencing framework, but local court culture differs significantly from Maricopa County. Kingman Municipal Court and Mohave County Superior Court operate with smaller dockets, and judges develop familiarity with individual officers and their arrest patterns. Derek’s history as a Mohave County prosecutor gives him direct insight into how these courts evaluate evidence and weigh defense arguments.
For arrests on the AZ-93 Phoenix-to-Vegas corridor, we examine the reason for the traffic stop, road conditions along the desert highway, and whether DPS troopers followed proper procedures for implied consent advisements. Long transport times from remote stops to the Kingman station can affect blood draw timing and BAC accuracy.
Derek Oliverson prosecuted DUI cases alongside many of the officers still active in Mohave County. He knows their training backgrounds, field sobriety testing habits, and report-writing patterns. We request body camera footage from Kingman PD, MCSO, and DPS, cross-referencing it against the written arrest report for inconsistencies.
Blood samples in Kingman are typically drawn at Kingman Regional Medical Center or by DPS phlebotomists. We verify chain-of-custody documentation, calibration records for intoxilyzer equipment at the Kingman PD station, and whether transport and storage protocols were followed for samples sent to the DPS Crime Lab in Phoenix.
As a former Mohave County prosecutor, Derek negotiates with the Mohave County Attorney’s Office from a position of shared institutional knowledge. He understands their case evaluation criteria, plea offer patterns, and what evidence they consider dispositive. For misdemeanor cases, he leverages familiarity with Kingman Municipal Court judges and their sentencing tendencies.
No other DUI defense attorney in Arizona brings Derek Oliverson’s combination of Mohave County prosecution experience, judicial service, and law enforcement background to Kingman cases.

He left the bench in 2014 to lead Oliverson Law PLLC full-time.
