Troopers from the Ohio State Highway Patrol, in conjunction with the Chillicothe Police Department and the Ross County Sheriff’s Department, will operate an OVI checkpoint to deter and arrest impaired drivers this week. The county where the checkpoint will take place will be announced the day prior to the checkpoint, and the location will be announced the morning of the checkpoint. Operational support for the sobriety checkpoint will be provided by local law enforcement agencies. Last Friday night in Circleville, Law Enforcement operated an OVI checkpoint, stopping 489 vehicles. 18 of those were diverted to check for possible drug impairment or drivers license violations. No arrests were made, however.
