What is the significance of counting steps during the Walk and Turn exercise?

Counting steps during the Walk and Turn exercise is significant because it assesses the individual's awareness and ability to follow instructions. This exercise requires the driver to listen to the officer's commands while simultaneously performing a physical task, which can reveal the driver's level of cognitive functioning. If a driver struggles to count their steps accurately or follow the sequence of the task, it may indicate impairment, as it demonstrates a lack of the mental clarity necessary to operate a vehicle safely. This cognitive assessment is crucial in determining whether further actions, like additional sobriety tests, are needed.
