Why is rephrasing instructions beneficial during SFSTs?

Rephrasing instructions during standardized field sobriety tests (SFSTs) is beneficial primarily because it clarifies expectations for the subject. When an officer restates the instructions in a more understandable manner, it ensures that the individual being tested fully comprehends what is required of them. Clear communication can minimize confusion and help the subject know exactly what to do, which is critical for the accuracy of the test results. Additionally, clear instructions can foster a more cooperative environment during the testing process, potentially leading to a more reliable assessment of the subject's sobriety and motor skills. This step can significantly influence the effectiveness and fairness of the assessment.
