In Ohio, at what blood alcohol concentration (BAC) level is it illegal for adults to drive?

In Ohio, it is illegal for adults to drive with a blood alcohol concentration (BAC) level of 0.08% or higher. This standard is set to ensure the safety of all road users, as higher levels of alcohol significantly impair an individual’s ability to operate a vehicle safely. At a BAC of 0.08%, drivers are more likely to experience reduced coordination, slower reaction times, and impaired judgment, which can lead to dangerous driving situations, increasing the risk of accidents. This legal limit is enforced to discourage driving under the influence and to promote responsible behavior among drivers. It's important to note that while lower levels of BAC might not constitute a legal offense, they can still impair driving abilities and pose risks.
