Which indicator might suggest a subject has a high level of intoxication?

Excessive stumbling or swaying is a strong indicator that a subject may be highly intoxicated. These physical symptoms often correlate with impaired motor control and balance, which are common effects of alcohol consumption. When an individual is under the influence, their coordination and stability can be significantly affected, leading to noticeable difficulties in walking steadily or maintaining an upright posture.

In contrast, rapid speech might suggest agitation or nervousness rather than intoxication, consistent eye contact could indicate a level of awareness or confidence, and a calm demeanor might actually suggest that the individual is not under the influence or is managing their behavior well despite any alcohol consumption. Therefore, observable physical disturbances like stumbling or swaying are critical signs for law enforcement when assessing an individual's level of intoxication.
