What should be done in case of conflicting information from the subject during an SFST?

When a subject provides conflicting information during a Standardized Field Sobriety Test (SFST), verifying the information through questioning is crucial. This approach allows the officer to clarify the subject’s statements and assess their coherence and credibility. By asking follow-up questions, the officer can gather more details that may reveal patterns or inconsistencies, contributing to a more accurate overall assessment.

Using this method also ensures that the officer maintains a professional demeanor, which can help in building rapport with the subject and possibly reducing their defensiveness. Understanding the reasoning behind the subject’s statements may uncover important insights that could impact the officer’s evaluation of impairment, leading to a more informed decision regarding the necessity of further testing or arrest.
