Which of the following is NOT a clue observed during the One Leg Stand test?

During the One Leg Stand test, potential clues indicating impairment are observed as the subject attempts to maintain balance on one leg. Hopping, putting the foot down, and swaying while balancing are all behaviors that demonstrate difficulty in maintaining stability and suggest a lack of coordination, which can be associated with impaired driving.

Talking, however, is not a standard clue identified in the context of this specific test. The primary focus of the One Leg Stand test is on physical balance and stability rather than verbal behaviors. Therefore, since talking does not directly impact or reflect performance in maintaining balance during the test, it is identified as the correct answer to the question regarding which behavior is not considered a clue observed during this test.
