During the instruction phase of the one leg stand, what is NOT an indicator of impairment?

Counting backwards is not an indicator of impairment during the one leg stand test. This test is primarily focused on the individual's ability to maintain balance on one leg while providing an assessment of their coordination and physical control. Indicators of impairment in the context of this test include actions that affect balance, such as putting the foot down, using arms for balance beyond a set threshold, or hopping. Each of these actions demonstrates a physical struggle to maintain stability, which is often indicative of impairment due to alcohol or other substances.

In contrast, counting backwards is not a part of the physical balance exercise but may be used as a cognitive task in other sobriety tests. The cognitive task of counting backwards does not directly relate to balance or coordination and thus is not considered an indicator of impairment while performing the one leg stand. Keeping these distinctions clear helps in accurately interpreting performance during sobriety evaluations.
