Which of the following is NOT a clue to look for during the Walk and Turn exercise?

In the context of the Walk and Turn exercise, maintaining balance with arms out is not typically considered a clue indicating impairment. This exercise is designed to assess an individual's ability to walk in a straight line while demonstrating balance and attention to instruction. When individuals perform this test, it is expected that they may naturally use their arms for balance, especially if they are attempting to remain steady while walking heel-to-toe.

The other clues, such as starting to walk before being instructed, breaking the heel-to-toe position, and counting steps incorrectly, are all indications that a person may not be fully capable of performing the task as required. These behaviors can suggest a lack of coordination or control, often associated with impairment. In contrast, using arms for balance can happen regardless of one's sobriety and does not inherently indicate a lack of physical control or focus. Thus, it is reasonable for this behavior to be excluded from the list of clues during the assessment.
