The correct answer is: When their faculties are impaired by alcohol consumption

A person is considered to be under the influence of alcohol when their faculties are impaired by alcohol consumption. This impairment can affect a person's judgment, coordination, reaction time, and overall ability to function normally, regardless of the specific amount of alcohol consumed. The legal definition typically focuses on the observable effects of alcohol on a person rather than just the number of drinks consumed or specific physical abilities like walking steadily. Impairment can manifest in various ways, making it the defining factor in determining whether someone is under the influence. The emphasis on observable impairment aligns with laws regarding driving under the influence and conducting field sobriety tests, which assess how alcohol affects a person's performance in real-time situations. Therefore, the assessment is focused on the ability to carry out regular tasks effectively, rather than a single drink or a specific physical symptom.
