What is the legal blood-alcohol concentration (BAC) limit for drivers aged 21 and above in Ohio?

In Ohio, the legal blood-alcohol concentration (BAC) limit for drivers aged 21 and above is set at .08 percent. This means that if a driver has a BAC of .08 percent or higher, they are considered legally impaired and can be charged with driving under the influence (DUI) or operating a vehicle while intoxicated (OVI).

This limit is established to help ensure the safety of all road users, as higher levels of alcohol consumption significantly impair motor skills, reaction times, and judgment, increasing the likelihood of accidents. Federal standards for impaired driving align with Ohio's .08 percent BAC limit, reflecting a uniform approach across many states aimed at enhancing road safety.

The other options reflect different limits that might apply in specific circumstances or for certain drivers, such as commercial drivers or underage individuals, but for general drivers aged 21 and older, the .08 percent limit is the standard legal threshold in Ohio.
