Yes. Although the legal limit for blood alcohol concentration (BAC) is .08%,
Ohio OVI laws state that anyone who operates a vehicle while under the influence of
alcohol, drugs, or a combination of both can be arrested for OVI. Officers
may still arrest and Courts may still convict a person with a BAC lower
than the legal limit if there is sufficient justification to believe they
are under the influence.
You also do not need to be actively driving or have your vehicle running
to be arrested for DUI. Simply being in the driver’s seat with the
radio or a/c on can be enough to constitute “physical control”
of a vehicle, and warrant an arrest.
