The Oklahoma Highway Safety Office and numerous agencies throughout the state, including Shawnee and Tecumseh police, as well as the Pottawatomie County Sheriff’s Office, will join six other states in the region to put a stop drug-impaired driving with enforcement efforts starting at midnight on April 20. Law enforcement agencies from across Oklahoma, Kansas, Iowa, Nebraska, Arkansas and Missouri will increase patrols, conduct checkpoints and raise awareness of the impacts of drug-impaired driving. The campaign will run for 42-hours and will focus on getting DUI drivers off Oklahoma roadways.
