During the Walk-and-Turn test, what is the proper number of steps taken in one direction?

In the Walk-and-Turn test, the proper number of steps taken in one direction is nine. This standardized number is an essential component of the test, as it is designed to assess a subject's balance, coordination, and ability to follow instructions. The test requires the individual to take nine heel-to-toe steps along a straight line, turn on one foot while maintaining balance, and return by taking another nine heel-to-toe steps. The expectation of completing nine steps provides a clear benchmark for officers to evaluate the performance of the subject.

Using this specific number allows for consistency across evaluations, ensuring that the test can be reliably administered and compared across individuals. It also aligns with the established protocols set forth by the National Highway Traffic Safety Administration (NHTSA) for accurately assessing potential impairment due to alcohol.
