For drivers over 21, what BAC is illegal?

Explanation:
Driving legality is defined by a specific blood alcohol concentration (BAC) threshold. For drivers who are 21 or older, the legal limit is 0.08% BAC. Reaching or exceeding 0.08% means you’re considered legally intoxicated and can be charged with driving under the influence, regardless of how you feel or how clearly you think you’re operating the vehicle. Impairment can begin at lower levels, which is why other rules exist for different groups: commercial drivers have a lower limit (0.04%), and drivers under 21 face zero tolerance (0.02% or higher is illegal). So the official threshold for adults is 0.08%.
