Kingman criminal lawyer Derek Oliverson defends residents of Mohave County’s seat — the gateway city along Interstate 40 and Historic Route 66 — against DUI, drug trafficking, assault, and domestic violence charges. Kingman’s strategic position as a crossroads between Phoenix (185 miles south), Las Vegas (100 miles northwest), and Flagstaff (140 miles east) means I-40 drug interdiction stops and highway DUI arrests are a constant enforcement reality in Mohave County.

Kingman is a city of approximately 32,000 people that serves as the county seat of Mohave County, Arizona’s fifth-largest county by area at over 13,000 square miles. The city sits at the junction of Interstate 40 and U.S. Route 93, which connects Phoenix to Las Vegas through the desert. That highway intersection makes Kingman a focal point for law enforcement — the Mohave County Sheriff’s Office, Kingman Police Department, and Arizona Department of Public Safety all patrol the corridors running through town.
Drug trafficking cases dominate the serious criminal docket in Kingman. The I-40 corridor between Needles, California and Flagstaff is a known narcotics transport route, and DPS troopers conduct aggressive interdiction stops on vehicles traveling through Mohave County. Officers look for out-of-state plates, minor traffic violations, and nervous behavior as pretexts to initiate vehicle searches. Fentanyl, methamphetamine, and marijuana seizures along this stretch of highway lead to state and sometimes federal charges filed in Kingman.
DUI enforcement in Kingman spikes along Stockton Hill Road — the main commercial strip — Andy Devine Avenue (Route 66), and the Hualapai Mountain Road corridor where residents travel between town and the Hualapai Mountain community. Unlike Maricopa County’s sprawling freeway system, Kingman’s compact geography means officers recognize repeat offenders and patrol the same handful of roads that connect bars, restaurants, and residential neighborhoods.
Domestic violence cases in Kingman reflect rural Arizona’s challenges. Long response times in outlying areas of Mohave County mean incidents often escalate before deputies arrive. The Kingman Justice Court and Mohave County Superior Court handle these cases with limited judicial resources compared to Maricopa County, which can mean faster trial dates but also less flexibility in plea negotiations.

Bar fights along Andy Devine Avenue, altercations at Mohave County fairgrounds events, and aggravated assault charges. Kingman’s small-town dynamics mean witnesses and reputations factor into every case.
Mandatory arrest cases in Kingman proper and remote Mohave County communities including Golden Valley, Bullhead City, and Lake Havasu City. Derek coordinates defense across multiple Mohave County justice courts.

The Mohave County Superior Court in Kingman at 401 E Spring Street handles all felony cases for the county’s 215,000 residents spread across 13,000 square miles. Unlike the massive Maricopa County system with dozens of judges and hundreds of prosecutors, Mohave County operates with a small bench and a compact County Attorney’s Office. That smaller system has both advantages and risks for defendants.
On one hand, Derek Oliverson can build closer working relationships with Mohave County prosecutors and judges than any attorney could in Phoenix’s volume-driven courts. Negotiations are more personal, and individual case circumstances carry more weight. On the other hand, rural courts have fewer diversion programs, less access to specialized treatment courts, and judges who see the same defendants repeatedly — meaning second chances are harder to come by.
Misdemeanor cases originating in Kingman city limits are heard at the Kingman Justice Court. Cases from unincorporated Mohave County areas — Golden Valley, Dolan Springs, Hackberry, Chloride — also funnel into Kingman-area courts. Bullhead City and Lake Havasu City have their own justice courts, but serious felonies from anywhere in Mohave County are adjudicated at the Superior Court in Kingman. Derek’s Kingman office on Beale Street places him within walking distance of both courthouses.
Interstate 40 drug interdiction stops in Mohave County often begin with a minor traffic violation — following too closely, a cracked windshield, or drifting across a lane line. Officers use these pretexts to initiate contact and then request consent to search or deploy a K-9 unit. The Fourth Amendment requires that any vehicle search be supported by probable cause or valid consent, and the U.S. Supreme Court has ruled in Rodriguez v. United States that officers cannot extend a traffic stop beyond its original purpose to wait for a drug dog. Derek examines every detail of the stop — the officer’s stated reason, the timing, body camera footage, and whether consent was truly voluntary — to identify constitutional violations that can result in evidence suppression and case dismissal.
Arizona DUI penalties are the same statewide, but the court process in Kingman differs from Phoenix in several ways. Mohave County has fewer judges and prosecutors, so cases typically move faster — arraignment to trial in weeks rather than months. Blood draws after DUI arrests are usually processed at Kingman Regional Medical Center, and the smaller lab processing pipeline means chain-of-custody challenges can be more effective. The Kingman Justice Court handles misdemeanor DUI with a more personal dynamic; judges and prosecutors know most defense attorneys by name. Derek leverages that familiarity to negotiate better outcomes while preparing aggressively for trial when the prosecution’s offer is not acceptable.
