Which physical actions can demonstrate clues during the One-Leg Stand test?

The One-Leg Stand test is designed to evaluate a person's balance and stability while performing a simple task that requires coordination. During this test, an individual is instructed to stand on one leg and raise the other leg approximately six inches off the ground while counting for 30 seconds. Observing physical actions that indicate impairment is crucial for the assessment.

Swaying, hopping, or lowering the foot are all behaviors that can indicate a lack of balance and coordination, which are commonly associated with impaired motor skills due to alcohol or drug influence. If a participant demonstrates any of these actions, it suggests that they may be struggling to maintain their balance, which is a critical aspect the law enforcement officer observes to determine impairment.

The other options do not effectively demonstrate the physical coordination and balance that the One-Leg Stand test is meant to assess. For instance, maintaining a straight posture is an indication of good balance but does not provide clues about impairment. Counting silently to thirty is part of the instructions for the test but does not directly relate to physical actions. Walking in a straight line is more relevant to the Walk-and-Turn test, not the One-Leg Stand, therefore, it does not apply here.
