What does a score of 4 or more clues on the Walk-and-Turn indicate?

A score of four or more clues on the Walk-and-Turn test indicates a high probability of impairment. This test is designed to assess a person's ability to perform divided attention tasks, which can be affected by alcohol or drug use. The test requires a subject to walk a straight line heel-to-toe, turn, and return in the same manner. Each clue observed, such as losing balance, not staying heel-to-toe, or failing to follow instructions, suggests a greater degree of impairment.

Four or more clues indicate that the individual's performance deviates significantly from the expected standard for sober individuals, which points to a strong likelihood that their motor skills and cognitive functions are impaired. The correlation between the number of clues present and the degree of impairment is well-documented in the context of Standardized Field Sobriety Tests. This assessment is crucial for law enforcement to determine a driver's ability to operate a vehicle safely.
