What is a false positive in the context of HGN testing?

• A. A condition where an individual shows signs of HGN but is actually impaired
• B. A condition where an individual shows signs of HGN but is not impaired by alcohol or drugs
• C. A correct identification of impairment through HGN testing
• D. A scenario where HGN testing indicates no impairment

Answer: (B)

In the context of HGN testing, a false positive refers to a situation where an individual exhibits signs of Horizontal Gaze Nystagmus, suggesting impairment, yet is not actually impaired by alcohol or drugs. This can happen for various reasons, such as natural variations in ocular movements, medical conditions, or other factors unrelated to substance use. Understanding false positives is crucial in the realm of HGN testing, as it emphasizes the importance of knowledgeable interpretation of the results. Officers and evaluators must consider that there are situations where the test may indicate impairment that does not correlate with actual intoxication levels. This distinction is essential to ensure accurate assessments and uphold the integrity of the testing process.
