How many inches must a person raise their arms in the Walk and Turn or One Leg Stand test to indicate a clue?

In both the Walk and Turn and One Leg Stand tests, a specific arm movement can indicate a clue when assessing a subject's coordination and balance. Specifically, when an individual raises their arms by 6 inches or more during these tests, it signifies a lack of control and balance. This particular measurement of 6 inches is an established threshold used in evaluating performance, as it demonstrates the person's difficulty in maintaining the correct stance and indicates a potential impairment.

The tests are designed to assess various physical abilities such as balance, coordination, and the ability to follow instructions, and the indicated clue of arm elevation becomes a critical factor in determining the driver's level of impairment. Understanding this detail is essential for accurately interpreting the results of field sobriety tests.
