What does the second 'I' clue refer to in the Walk and Turn test?

The second 'I' clue in the Walk and Turn test refers specifically to an "Incorrect number of steps." This is important because the test requires the individual to take nine heel-to-toe steps in one direction, turn on one foot, and then return back with nine heel-to-toe steps.

During the assessment, if a subject takes more or fewer steps than instructed, it demonstrates a lack of ability to follow simple instructions, which is indicative of impairment. Accurate counting and adherence to the specified number of steps is a critical part of the evaluation process, as it not only tests physical coordination but also cognitive function and the ability to follow directions.

Other potential clues related to the test, such as rhythm, balance, and starting position, are also evaluated, but the second 'I' specifically highlights the importance of maintaining the correct number of steps in accordance with the test’s parameters. This attention to detail in step count is key for effective assessment of a subject's sobriety.
