With nearly 400 DUI/OVI related fatalities per year, Ohio has implemented strict rules governing second offenses. (The state also refers to DUI's by the term “operating a vehicle under the influence,” which is shortened to OVI in its statutes.
In Ohio, the term "OVI" ("Operating a Vehicle Intoxicated") is used to describe DUI offenses, which include both drugs and alcohol. (DUI and OVI are used interchangeably.) While .08 BAC is the legal limit pertaining to alcohol, it is illegal to drive with any amount of a controlled substances (drugs) present in the driver's blood.
Sobriety checkpoints are legal in Ohio (see State v. Bauer, 651 N.E.2d 46 (Ohio App. 10 Dist.1994)). These checkpoints (also referred to as "mobile checkpoints" or "roadblocks") are police traffic stops that are not tied to any specific or individual suspicions.
In Ohio, if you get pulled over for an OVI (operating a vehicle under the influence) and the officer asks you to take a blood, breath, or urine test, do you have to take one? What happens if you refuse?
