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

The legal blood alcohol concentration (BAC) limit for drivers aged 21 and over in Ohio is 0.08%. This standard is established to help identify when a driver is impaired and to promote safer roads. When a driver's BAC reaches this level, it is assumed they have lost the ability to operate a vehicle safely, thereby increasing the risk of accidents. Ohio adheres to this limit in alignment with national norms, as many states also utilize a 0.08% threshold for legal intoxication.

Maintaining this legal BAC limit helps law enforcement effectively combat drunk driving and ensures that all drivers are held to the same standard regardless of their experience or background. A lower BAC limit, such as 0.05%, might apply to other specific situations, such as for novice drivers or commercial drivers, but for the general population of drivers over 21, 0.08% remains the critical figure for legal responsibility.
