Which test includes instructions, heel-to-toe walking, and return walk?

• A. Horizontal Gaze Nystagmus
• B. Walk-and-Turn
• C. One-Leg Stand
• D. Breath Analysis

Answer: (B)

The Walk-and-Turn test is designed to assess an individual's ability to follow instructions and perform physical tasks simultaneously, which is indicative of their cognitive and motor skills. During the test, a person is instructed to take a series of heel-to-toe steps in a straight line, then turn on one foot and walk back to the starting point in the same manner. This specific structure—following detailed instructions, the heel-to-toe walking, and the return walk—makes it particularly effective in determining whether an individual is impaired. The test evaluates balance, coordination, and the ability to concentrate, which can be affected by alcohol or drugs. In contrast, the other options do not incorporate heel-to-toe walking or the requirement for a return walk: the Horizontal Gaze Nystagmus focuses on tracking a moving object with the eyes, the One-Leg Stand assesses balance while standing on one leg without walking, and Breath Analysis is a method for measuring blood alcohol content rather than a physical performance test. This distinction underlines why the Walk-and-Turn test is the correct answer.
