The state of Maine refers to a DUI as an OUI (Operating Under the Influence) and prescribes criminal and administrative penalties. These penalties are more severe if there are aggravating factors which include a BAC of .15% or more and traveling 30 m.p.h. or more over the speed limit
Maine’s OUI laws apply not only to alcohol, but also to all other intoxicants. An intoxicant is any substance that can lead to impairment, including illegal drugs, marijuana, and prescription medications.
