Which of the following is NOT a clue during the Walk-and-Turn test?

During the Walk-and-Turn test, the primary objective is to assess an individual's ability to follow instructions and maintain balance while performing a series of physical tasks. The clues observed during this test are critical indicators of potential impairment due to alcohol or drugs.

Maintaining balance is a significant factor because individuals should be able to stand steadily while taking steps. If they struggle with balance, it may indicate impairment. Counting steps accurately is another essential clue; the ability to correctly count each step shows that the participant can follow instructions and process information as expected. Turning properly is also a vital component of the test, as it requires coordination and the ability to perform the task as instructed without additional cues or assistance.

Clenching fists, however, is not considered a clue in the context of the Walk-and-Turn test. This action does not directly correlate with the candidate's ability to perform the test or indicate any level of impairment. Instead, it might be an involuntary response that is not related to the key performance indicators observed during this sobriety test. Thus, identifying clenching fists as a non-clue helps focus on the actual behaviors assessed during the Walk-and-Turn.
