During the One-Leg Stand, what should officers discourage?

During the One-Leg Stand test, discouraging the use of arms for balance is important because this action can indicate a lack of balance and coordination that is being assessed during the test. The purpose of this sobriety test is primarily to assess an individual's ability to maintain balance while standing on one leg without the assistance of arms, which may suggest impairment. When officers enforce this guideline, it helps ensure that the test results accurately reflect the test subject’s true level of impairment.

In contrast, while looking down at the ground, excessive swaying, and fidgeting of the foot may also illustrate issues with balance or focus, they do not directly affect the integrity of the test in the same way that using arms for support does. Thus, minimizing arm use is critical for an authentic evaluation of the subject's sobriety during this field sobriety test.
