What does the seated FST battery consist of?

The seated FST (Field Sobriety Test) battery primarily assesses an individual's coordination and ability to follow instructions, which are critical components in evaluating potential impairment due to substances, particularly alcohol. The correct components of this test include the horizontal gaze nystagmus, finger-to-nose test, palm pat, and hand coordination exercises.

The horizontal gaze nystagmus test evaluates the individual's ability to track a moving object with their eyes, which can indicate impairment if nystagmus (involuntary eye movement) is observed. The finger-to-nose test assesses proprioception and coordination, while the palm pat and hand coordination tests further evaluate the subject's motor skills and ability to perform tasks requiring dexterity. Together, these tests create a comprehensive evaluation for law enforcement when determining impairment levels.

The other choices mention tests that are either not typically part of the seated FST battery or do not accurately reflect the concept of seated assessments specifically designed to measure cognitive and motor skills related to an operator's ability to operate a vehicle safely.
