• C. In a controlled laboratory environment.
• D. At a training academy.

Answer: (B)

The Horizontal Gaze Nystagmus (HGN) test is typically administered during a roadside stop or at a DUI checkpoint because it is a field sobriety test used by law enforcement to assess a driver's level of impairment due to alcohol or drugs. This test allows officers to observe the involuntary eye movement that occurs when a person is intoxicated, making it a practical tool for evaluating potential impaired driving immediately after a traffic stop. Administering the test in this context is crucial for law enforcement as it provides real-time evidence of a driver's ability to operate a vehicle safely, which is essential for making decisions about further testing or arrests. Conducting the HGN test in a setting like a medical facility, controlled laboratory, or training academy would not be practical for on-the-spot assessments of impaired driving, which is why those settings are not appropriate for this specific test.
