Which statement lists the three tests commonly used in standard field sobriety testing?

• A. Breathalyzer, blood test, and urine test.
• B. Heel-to-Toe, Romberg, and finger-to-nose.
• C. Walk-and-Turn and One-Leg Stand only.
• D. Horizontal Gaze Nystagmus; Walk-and-Turn; One-Leg Stand.

Answer: (D)

The main idea is recognizing the standard field sobriety test battery. The three tests used together are Horizontal Gaze Nystagmus, Walk-and-Turn, and One-Leg Stand. They’re designed to assess impairment through different means: Horizontal Gaze Nystagmus looks for involuntary eye jerks that intensify with alcohol; Walk-and-Turn requires following instructions while balancing and counting steps, testing divided attention, balance, and coordination; One-Leg Stand measures balance and concentration by seeing how long a person can stand on one leg. These three together are the validated SFST set commonly used to gauge impairment and establish probable cause for arrest. Breathalyzer, blood, and urine tests are chemical or lab tests, not the field sobriety tests administered on the roadside. Heel-to-Toe, Romberg, and finger-to-nose are balance or coordination tests not part of the standard SFST battery, and Walk-and-Turn plus One-Leg Stand alone miss the eye-tracking component. Horizontal Gaze Nystagmus; Walk-and-Turn; One-Leg Stand includes all three standard components, making it the best choice.
