According to the San Diego study, what is the accuracy percentage of the Walk and Turn test?

1. 83%

2. 79%

3. 69%

4. 85%

The correct answer is: 79%

In the context of the Walk and Turn test, as referenced in the San Diego study, the accuracy percentage refers to the reliability of this particular field sobriety test in assessing an individual's level of intoxication. The figure of 79% indicates that when the Walk and Turn test is performed, it correctly identifies individuals with a blood alcohol concentration (BAC) above the legal limit a significant majority of the time. This level of accuracy demonstrates that the test has a reliable correlation with impaired driving assessments. A noted accuracy of 79% reinforces the test's effectiveness, as it strikes a balance between being sufficiently precise and practicable for use by law enforcement officers in the field. While not perfect, it provides a valuable tool for officers to determine impairment due to alcohol consumption. As a result, this statistic underscores the importance of the Walk and Turn test as part of a comprehensive approach to evaluating sobriety during traffic stops and enhancing public safety.
