The OVI Law in Ohio
In Ohio the offense is OVI, and the limit is 0.08.
Driving in Ohio is consent to a breath or blood test when an officer has cause to suspect OVI; the license case that follows a refusal or a failed test is run by the Bureau of Motor Vehicles, separately from the criminal case.
For charging and sentencing, Ohio counts prior offenses within 10 years.
Who Makes OVI Arrests in Knox County
The Knox County Sheriff's Office and the agencies that report for Mount Vernon, Fredericktown and Danville make the OVI arrests in Knox County.
Together, the three agencies in Knox County with all twelve months of 2024 on file reported 290 arrests to the FBI that year, all offenses together; the FBI's count for Knox County does not break OVI out.
The Utica Police Department is listed by the FBI across two counties including Knox County, so its arrests are not broken out for Knox County here.
