A thorough interpretation of Horizontal Gaze Nystagmus (HGN) test results relies heavily on considering other field sobriety test results. HGN is one of several tests used to assess a driver's level of impairment, particularly from alcohol or drugs. By analyzing the results of HGN in conjunction with other field sobriety tests, such as the walk-and-turn or one-leg stand tests, a more comprehensive evaluation of the individual's overall physical and cognitive abilities is established.

This broader context is crucial as it provides additional evidence that can support the assessment of impairment. A solitary HGN test, while informative, does not capture the complete picture of a subject's ability to operate a vehicle safely, hence the importance of correlating it with the results of other sobriety evaluations. This multi-faceted approach enhances the reliability of the findings and supports law enforcement in making informed decisions regarding potential impairment.
