having drunk enough [alcohol] to disturb the action of the physical or mental faculties so that they are no longer in their natural or normal condition; that therefore, when a person is so affected by intoxicating liquor as not to possess that clearness of intellect and control of himself that he would otherwise have, he is "under the influence of intoxicating liquor[.]" Christianson v. N.D. Dir., Dep't of Transp. , 951 N.W.2d 231, 237-38 (N.D. 2020) (quoting North Dakota v. Berger , 683 N.W.2d 897, 901 (N.D. 2004) ). The "effect" of the "intoxicating liquor," not the "amount," determines whether a person is "under the influence" under North Dakota law. Christianson , 951 N.W.2d at 238 (citing North Dakota v. Hanson , 73 N.W.2d 135, 140 (N.D. 1955) ).
