Understanding the Legal Definition of Under the Influence of Alcohol

Definition & Meaning

The phrase "under the influence of alcohol" refers to a state in which alcohol consumption has impaired a person's ability to operate a vehicle safely. This impairment affects the nervous system, brain, or muscles, making it difficult for the individual to drive as a reasonable and cautious person would under similar circumstances. Essentially, if someone is under the influence, they may not be able to control their vehicle effectively due to the effects of alcohol.
