What is the probability of a suspect being above a .08 BAC with two clues for the walk and turn test?

What is the probability of a suspect being above a .08 BAC with two clues for the walk and turn test?

• A. 79%
• B. 85%
• C. 72%
• D. 90%

Answer: (A)

The answer indicating a probability of 79% suggests that, based on statistical data and research regarding performance on field sobriety tests, there is a high likelihood that a suspect who exhibits two specific clues while performing the walk and turn test has a blood alcohol concentration (BAC) above .08. The walk and turn test is designed to measure an individual’s ability to follow instructions and maintain balance, both of which can be impaired by alcohol consumption. When a suspect demonstrates two indicators of impairment during this test, it reflects significant enough impairment that correlates strongly with a BAC level over the legal limit for driving. Research in the field of traffic safety and alcohol impairment frequently asserts that there is a clear connection between observable signs during sobriety tests and measurable levels of intoxication, validating that a higher number of clues detected during such tests increases the likelihood of an elevated BAC. Thus, the 79% figure is grounded in empirical studies that establish this correlation, making it a reliable estimate for law enforcement officers evaluating suspected impaired drivers. Consequently, this probability not only supports the reliability of the walk and turn test as a field sobriety indicator but also reinforces the broader understanding of how specific performance cues relate to BAC levels in suspected cases of driving under the influence
