For an ordinary noncommercial driver aged 21 or older, at what alcohol level does Maine’s numerical criminal OUI threshold begin?
Correct answer: 0.08 grams per 100 milliliters of blood or 210 liters of breath
Why
Maine’s numerical OUI provision applies at 0.08 grams or more of alcohol per 100 milliliters of blood or 210 liters of breath. OUI also includes operating while under the influence of intoxicants; being below the numerical threshold is not permission to drive impaired. Under-21 license conditions and commercial-driving rules are separate.
