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

The correct response points out that touching heel-to-toe is actually a requirement of the Walk-and-Turn test, rather than a clue indicating impairment. The Walk-and-Turn test involves a series of specific movements, including walking in a straight line heel-to-toe and then turning to walk back. The purpose of this test is to assess an individual's ability to follow instructions and maintain balance while performing the task.

The other items are also integral clues used to evaluate potential impairment during the test. Stepping off the line, not looking at the ground, and taking an incorrect number of steps are all observed behaviors that suggest a lack of coordination or inability to follow the instructions properly. Each of these actions demonstrates difficulty in balance or cognitive processing, which are critical indicators used by officers when assessing a person's level of sobriety.
