• A. 80
• B. 85
• C. 88
• D. 92

Answer: (C)

The Horizontal Gaze Nystagmus (HGN) test is a field sobriety test used to assess an individual's level of impairment, particularly in relation to alcohol consumption. According to the findings of the San Diego study, the HGN test is statistically capable of accurately identifying whether a subject has a Blood Alcohol Concentration (BAC) of 0.08 or higher approximately 88% of the time. This high accuracy rate makes the HGN test a reliable tool for law enforcement officers when evaluating potential DUI (driving under the influence) cases. The significance of this percentage lies in its practical application; law enforcement can confidently use the results of the HGN test in conjunction with other evidence to make informed decisions about arresting individuals suspected of driving under the influence. Understanding this statistic is crucial for officers as it reinforces the validity of the test in the field and emphasizes the importance of conducting it correctly for effective assessment of a person’s impairment.
