Question

what is the legal limit of blood alcohol concentration for adults? 0.08% 0.10% 0.02% zero tolerance

Explanation:

In many regions, the legal limit of blood alcohol concentration (BAC) for adults driving is 0.08%. 0.10% was an older limit in some places but has been updated. 0.02% is often for minors (zero - tolerance for minors in some cases, but the question is about adults). Zero - tolerance usually applies to specific groups like minors or commercial drivers in some contexts, not the general adult BAC limit for non - commercial driving.

Answer:

0.08%
