What is the indication of two or more clues during a one-leg stand test?

When two or more clues are observed during a one-leg stand test, it suggests significant impairment consistent with a Blood Alcohol Concentration (BAC) of 0.08 or greater. The one-leg stand test is designed to assess an individual's ability to maintain balance and perform tasks under physical and cognitive stress, which can be negatively affected by alcohol consumption. The presence of multiple clues, such as swaying, using arms for balance, or putting a foot down, indicates a high likelihood of impairment, as these are expected to manifest at higher BAC levels.

Therefore, if an individual shows two or more clues during this test, it is a clear indication that they are under the influence of alcohol, aligning with the legal threshold of 0.08 BAC typically used to define impaired driving. This reflects the consensus in law enforcement training regarding alcohol impairment and supports the importance of standardized field sobriety tests in evaluating a driver's ability to operate a vehicle safely.
