What is a common misconception about the SFST?

A common misconception about the Standardized Field Sobriety Test (SFST) is that it is solely focused on assessing physical performance, which is reflected in the chosen answer. In reality, the SFST is a comprehensive evaluation that encompasses both physical and cognitive aspects.

While the tests do involve physical tasks, such as balancing or walking a straight line, they also require cognitive abilities like understanding instructions and making judgments. This dual assessment allows officers to get a more accurate picture of a person's overall impairment. Relying solely on physical performance ignores the critical cognitive components, which can play a significant role in a driver's ability to operate a vehicle safely.

Understanding this misconception is important for those studying SFST, as it emphasizes the need for a holistic view of impairment that includes both physical and mental faculties.
