For a noncommercial driver age 21 or older, at what blood-alcohol concentration does Kentucky’s adult per-se DUI threshold begin?
Correct answer: 0.08%
Why
The adult per-se threshold is 0.08 grams of alcohol per 100 milliliters of blood, expressed here as 0.08%. KRS 189A.010 specifies a scientifically reliable sample taken within two hours after operation or physical control ends for this per-se provision. Driving under the influence can also violate the law below 0.08; the threshold is not a safe drinking allowance.
