What should the suspect do with their arms during the One-Leg Stand test?

In the One-Leg Stand test, the correct action for the suspect is to keep their arms at their sides. This position helps to ensure that the test is conducted in a standardized manner, allowing for consistent assessment of the individual's balance and coordination. By having their arms at their sides, the suspect is less likely to use them for support, which could mask potential signs of impairment. This is a critical aspect of the test, as it helps the officer objectively evaluate whether the suspect can maintain balance while standing on one leg for a specific duration, typically 30 seconds. In contrast, other arm positions, such as raising them above the head or crossing them over the chest, would alter the test's conditions and make it more challenging, potentially affecting the outcome and the officer's assessment.
