Which option is NOT listed as a Standardized Field Sobriety Test in the material?

• A. Vertical leg stand
• B. Walk and turn
• C. Horizontal Gaze Nystagmus
• D. Finger to nose

Answer: (D)

The main idea here is knowing which tests are the standardized field sobriety tests (SFST) taught and validated for impairment assessment. In the SFST framework, the three recognized tests are Horizontal Gaze Nystagmus, Walk-and-Turn, and One-Leg Stand. These are the tests that agencies are trained to administer and motorists are evaluated against. Finger to nose is not part of that standardized SFST battery. It’s a general coordination/neurological assessment sometimes used in other contexts, but it isn’t listed as a Standardized Field Sobriety Test in the material. That’s why this option is the best choice for the one not listed. The other options map onto the standard SFSTs (Horizontal Gaze Nystagmus and Walk-and-Turn are clearly part of the three, and One-Leg Stand is the third), so they would be listed as SFSTs.
