What is the first phase of the walk and turn test?

The first phase of the walk and turn test involves providing verbal instructions to the participant, which is essential for ensuring that they understand the test procedure and the expectations. During this phase, the officer explains how the test will be conducted, emphasizing the specifics of the tasks that the subject will need to perform, thus allowing them to prepare mentally for the test.

Providing clear verbal instructions is crucial for the integrity of the test, as it is designed to assess the individual's balance and coordination while walking a straight line and subsequently returning. This phase sets the stage for the participant to engage in the walking and balancing tasks that follow, ensuring that they are aware of what is required of them.

Other choices may refer to different parts of the test that follow the instruction stage, but the initial step focuses on communication and clarity of the process. Thus, the verbal instructions are foundational for the subsequent phases of the test.
