According to the San Diego study, what percentage of the time can the One Leg Stand test determine if a subject's BAC is above 0.08?

• A. 65%
• B. 75%
• C. 79%
• D. 85%

Answer: (C)

The One Leg Stand test is a field sobriety test commonly used to assess a subject's level of impairment due to alcohol consumption. According to the San Diego study, this particular test demonstrates a high level of accuracy in determining whether a person's blood alcohol concentration (BAC) exceeds the legal limit of 0.08%. In this study, the One Leg Stand test accurately identified that a subject's BAC was above 0.08% approximately 79% of the time. This statistic is significant as it highlights the reliability of the test in practical law enforcement scenarios where officers need to make quick assessments of suspected intoxication. The test requires the individual to balance on one leg while counting, which is challenging for those impaired by alcohol, thereby providing a clear indication of impairment. The percentage reflects the test's ability to correlate with measured BAC levels, which is crucial for legal and procedural standards in DUI enforcement. This is particularly important since law enforcement officers rely on field tests to gather evidence that supports their observations and decisions regarding sobriety and safe driving capabilities.
