BAC Limits in Maine
For drivers 21 and over, the legal BAC limit is 0.08%. For commercial vehicle operators, it is 0.04%. Drivers under 21 are subject to a “zero tolerance” policy, making it illegal to drive with any measurable amount of alcohol (0.00% BAC).
You can be arrested for OUI (Operating Under the Influence) if your driving is impaired, even if your BAC is below these limits. Impairment can be caused by alcohol, illegal drugs, or prescription medications.
