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 Warren County
The Warren County Sheriff's Office and the agencies that report for Mason, Lebanon, Springboro, Franklin, Carlisle, Waynesville and two more cities make the OVI arrests in Warren County.
Together, the seven agencies in Warren County with all twelve months of 2025 on file reported 1,398 arrests to the FBI that year, all offenses together; the FBI's count for Warren County does not break OVI out.
The Monroe Police Department, the Middletown Police Department and the Loveland Police Department are each listed by the FBI across several counties including Warren County, so their arrests are not broken out for Warren County here.

The Records an OVI Leaves
