According to original research, how many clues detected in the One-Leg Stand suggest a BAC above 0.10?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

The One-Leg Stand test is designed to assess a person's balance and coordination, which can be affected by alcohol consumption. Research has indicated that the presence of certain clues during this test can be indicative of a higher blood alcohol concentration (BAC). Specifically, if two or more clues are detected in the performance of the One-Leg Stand, it suggests a BAC level above 0.10. This finding comes from studies examining the reliability of the One-Leg Stand in recognizing levels of impairment. Each clue observed during the test—such as swaying, using arms for balance, hopping, or putting the foot down—provides insight into the individual's control and stability. When two or more of these indicators are noted, the likelihood of significant impairment increases, correlating strongly with a BAC of 0.10 or higher. Consequently, this understanding is fundamental for law enforcement and professionals involved in sobriety assessments.
