What is the primary goal of HGN testing in Arizona?

• A. To gather data on traffic patterns
• B. To ensure road safety by identifying impaired drivers
• C. To conduct research on alcohol consumption
• D. To provide educational resources for drivers

Answer: (B)

The primary goal of Horizontal Gaze Nystagmus (HGN) testing in Arizona is to ensure road safety by identifying impaired drivers. HGN is a critical field sobriety test used by law enforcement to assess a driver's level of impairment, particularly due to alcohol or other substances. The basis for HGN testing lies in the observation of involuntary eye movements that are often associated with intoxication. When conducting the test, officers look for distinct signs of impairment, such as the eyes’ inability to smoothly follow a moving object, which can indicate a driver’s blood alcohol concentration (BAC) level. By detecting these signs, law enforcement can take appropriate action to prevent impaired individuals from operating vehicles, thereby enhancing overall road safety and reducing accidents related to impaired driving. The other options address unrelated goals. For instance, gathering data on traffic patterns does not directly connect to the assessment of driver impairment, nor do conducting research on alcohol consumption or providing educational resources for drivers pertain to the immediate objectives of an HGN test. The focus of HGN is specifically on evaluating a driver's current state rather than broader educational or research initiatives.
