How should the Walk-and-Turn test be initiated?

The Walk-and-Turn test should be initiated with clear verbal instructions and a demonstration to ensure that the participant understands the task they are required to perform. Providing clear instructions helps eliminate confusion and establishes a standard for how the test should be conducted. This part of the process is crucial, as it sets the tone for the evaluation and ensures that the subject knows exactly what is expected of them. Demonstrating the test allows the subject to visually see the steps involved, which aids in comprehension and helps the officer observe how well the subject can follow instructions.

By employing this method, it not only facilitates a smooth execution of the test but also helps in assessing the subject's ability to follow instructions and maintain balance, both of which can be indicators of impairment. Other methods like casual conversation, asking the subject to walk away, or using sign language do not provide the necessary clarity or engagement needed for accurately conducting the test.
