What BAC is allowed for 21-year-olds or older?

Explanation:
For drivers 21 and older, the legal per‑se limit is 0.08 BAC. That means if you have 0.08 or more, you’re considered legally intoxicated while driving and can be charged with DUI. Numbers below that, like 0.07 or 0.05, are under the per‑se limit, so they aren’t automatically DUI based on BAC alone (though impairment can still lead to charges if your driving is affected). The 0.09 option is above the limit and would be illegal. So the threshold you must stay under is 0.08.
