Which of the following is NOT one of the clues for the walk and turn test?

The correct answer highlights a crucial aspect of the walk and turn test, which is designed to assess a person's physical coordination and balance under the influence of alcohol or other substances. Maintaining heel-to-toe balance is actually expected during the test, as it indicates that the individual is performing the task as instructed.

In contrast, if a person needs to use their arms for balance, starts the test before the instructions are finished, or loses balance during the initial instructions, those behaviors are all considered clues that may indicate impairment. These signs can suggest that the individual may not be able to perform the task successfully, which is the underlying purpose of conducting this test in a field sobriety assessment. Maintaining the heel-to-toe position is a demonstration of proper execution of the test rather than an indication of impairment.
