Which items are part of the Standardized Field Sobriety Test (SFST) components commonly taught to law enforcement?

• A. Walk and Turn
• B. Horizontal nystagmus
• C. Both Horizontal nystagmus and Walk and Turn
• D. One-Leg Stand

Answer: (C)

SFSTs are three standardized tests used to assess impairment: Horizontal Gaze Nystagmus, Walk-and-Turn, and One-Leg Stand. The question asks which items are part of the SFST components commonly taught. Horizontal nystagmus and Walk-and-Turn are both core components of the SFST protocol, so a choice that combines them correctly reflects the taught components. Horizontal Gaze Nystagmus tests eye movements to detect intoxication, while Walk-and-Turn evaluates balance and divided attention through a specific walking sequence. Although One-Leg Stand is also part of SFST, the option that includes both HGN and Walk-and-Turn identifies two standard, widely taught components.
