For an Indiana driver aged 21 or older operating a noncommercial vehicle, at what blood alcohol concentration does the general per-se alcohol offense begin?
Correct answer: 0.08% or higher.
Why
The general per-se alcohol offense begins at 0.08% BAC; a higher offense level applies at 0.15% or more. The threshold is not a safe drinking target: driving while intoxicated is a separate offense, and impairment can occur below 0.08%. The under 21 alcohol rule is also separate.
