What is the BAC level for 21 years?

In the United States, the legal Blood Alcohol Concentration (BAC) limit for drivers aged 21 and over is 0.08%. This means that a person with a BAC of 0.08% or higher is considered legally impaired for the purposes of operating a vehicle. It's important to note that even at lower BAC levels, individuals may still experience impairments that can affect their ability to drive safely.
