What is the likelihood of a suspect being above a .08 BAC with 2 clues from the walk and turn test?

The likelihood of a suspect being above a .08 BAC with two clues from the walk and turn test is best represented by 79%. The walk and turn test is a standardized field sobriety test that examines a person's ability to follow instructions and maintain balance, both of which can be impaired by alcohol.

Research and studies indicate that the presence of specific clues during this test correlates highly with elevated blood alcohol content levels. If an individual exhibits two of these clues, statistical data suggests that there is a significant probability they may have a BAC over the legal limit of .08. The figure of 79% reflects a well-established correlation based on empirical data collected in field studies, illustrating that individuals showing two clues during the walk and turn test have a strong likelihood of being over this BAC threshold.

The other choices propose higher probabilities, which would not align with the data on the specificity and sensitivity of the test based on the number of clues exhibited. Thus, 79% is the correct answer, as it provides a realistic assessment based on established testing outcomes.
