Driver accused of DUI in multi-car injury crash on Highway 51

  STILLWATER — A 21-year-old man accused of traveling the wrong way on Highway 51 while under the influence of alcohol and marijuana at 8:21 am on June 21 was arraigned on Nov. 4 on a two-count felony DUI charge alleging he caused a multi-vehicle collision that resulted in injuries to three drivers including himself.

   Landon Brandt Primeaux of Shawnee, who has been released on $50,000 bond pending a Dec. 16 court appearance, was driving eastbound in the westbound lanes of Highway 51 near S. Cottonwood Road in Payne County when the crash occurred, Oklahoma Highway Patrol Trooper Tyler Burns alleged in an affidavit.

   “Primeaux sustained severe injuries and became trapped,” inside his 2026 Hyundai Elantra, the affidavit said. Emergency personnel extricated Primeaux from the vehicle, and he was transported by LifeNet to OU Medical Center in Oklahoma City, the affidavit said.

   The driver of a 2025 Honda Accord that was hit head-on, sustained “a traumatic brain injury, left clavicle fracture, multiple broken ribs, lung contusion, cervical spine fracture, lumbar compression injury, compound fracture of the right forearm, maxillofacial fractures, multiple lacerations and abrasions; he was transported for emergency medical treatment due to the severity of his injuries,” the affidavit said.

   Following the first crash, the driver of a 2018 Toyota RAV4 collided with the 2025 Honda Accord’; she “sustained multiple bruises, abrasions and generalized soreness throughout her body because of the collision,” the affidavit said.

   “Due to the severity of his injuries and immediate transport from the scene, Trooper Burns was unable to have direct contact with Primeaux. Trooper T. Jones and Payne County Sheriff’s Deputy Z. Wheeler had contact with Primeaux during the incident and will provide supplemental reports documenting their observations and interactions.

   “While conducting the collision investigation, Trooper Burns observed several open containers of alcoholic beverages inside (Primeaux’s car) including open containers of Bud Light, Busch Light and Beatbox alcoholic beverages. Trooper Burns also detected a strong odor of burnt marijuana coming from the vehicle and located an empty marijuana dispensary container inside (his car).

   “Based on the totality of the circumstances, including Primeaux operating his vehicle the wrong direction in the westbound lanes of State Highway 51, the presence of multiple open containers of alcoholic beverages inside the vehicle, the odor of burnt marijuana, and the severity of the resulting collision, Trooper Burns developed probable cause to believe Primeaux was operating a motor vehicle while under the influence of alcohol, drugs, or a combination thereof,” the affidavit alleged.

   A sample of Primeaux’s blood was collected and submitted to the Oklahoma State Bureau of Investigation for toxicological analysis, the affidavit said.

   If convicted of both felony counts in Payne County, Primeaux, who had previously received six months’ probation under a deferred sentence for misdemeanor DUI in Pottawatomie County in 2023, could be imprisoned for as long as 25 years, court records show.
