What is a common sign of alcohol impairment?

Slurred speech is a common sign of alcohol impairment because it directly relates to how alcohol affects the central nervous system, specifically by impacting coordination and motor functions. When someone consumes alcohol, it can hinder their ability to control the muscles involved in speech, resulting in an inability to articulate words clearly. This symptom often becomes noticeable as a person’s blood alcohol content increases, making it a key indicator of impairment during discussions or interactions. Recognizing slurred speech can be crucial for law enforcement and correctional officers as it can signal that an individual may be under the influence, thus affecting their behavior and decision-making abilities.
