At what minimum blood alcohol concentration (BAC) is an adult legally considered intoxicated?

Answer options

Why

Nearly every state treats an adult whose BAC reaches 0.08% as legally intoxicated (Utah sets a stricter 0.05% limit), while lower cutoffs apply to commercial drivers and to anyone under 21. Judgment and balance start to slip well before 0.08%, so the safest plan is not to ride after drinking.
