During which stage of the Walk and Turn test is the subject required to count their steps aloud?

The correct choice indicates that the subject is required to count their steps aloud during the walking stage of the Walk and Turn test. This stage is crucial because it tests not only the subject's ability to maintain balance while walking but also their capacity to perform a cognitive task simultaneously. Counting steps aloud adds an element of distraction, which can reveal impairments in divided attention that often accompany alcohol influence or other forms of impairment. The act of counting while performing a physical task is designed to assess the subject's coordination and cognitive function, making it a pivotal part of the overall evaluation in the test.
