For an adult driving an ordinary noncommercial vehicle, what is Colorado’s minimum BAC threshold for DUI per se?
Correct answer: 0.08%.
Why
DUI per se applies at a BAC of 0.08% or more while driving or within two hours after driving. This numerical threshold does not make a lower BAC safe: DUI or DWAI may be proved by actual impairment. Commercial and underage rules have separate provisions.
