What does the absence of swaying during the One-Leg Stand test suggest?

The absence of swaying during the One-Leg Stand test indicates potential sobriety or lower levels of impairment. This test is designed to assess a person's ability to maintain balance while performing a simple task, which requires coordination and stability. When a subject can stand on one leg without swaying, it suggests their motor skills and balance are functioning well, which are typically impaired by alcohol or drug use.

A person under the influence often has difficulty with balance and may find it challenging to remain steady on one leg. Therefore, the absence of swaying can be viewed as a positive indicator that the individual is not significantly impaired.

It's important to consider that while the absence of swaying is a strong indicator of possible sobriety, other factors can affect a person's performance on this test, such as fatigue or previous injuries. However, when evaluating the results specifically related to intoxication levels, the observed stability during the One-Leg Stand test is a more definitive sign of lower impairment.
