Horizontal gaze nystagmus (HGN) is a field sobriety test designed to help police officers identify suspected drunk drivers. Specially trained officers examine suspects' eyes for involuntary side-to-side jerking movements that begin to occur as blood alcohol concentrations approach statutorily prohibited limits. These eye movements are involuntary, they cannot be practiced, and they are not affected by drinker tolerance.

520 # $a Horizontal gaze nystagmus (HGN) is a field sobriety test designed to help police officers identify suspected drunk drivers. Specially trained officers examine suspects' eyes for involuntary side-to-side jerking movements that begin to occur as blood alcohol concentrations approach statutorily prohibited limits. These eye movements are involuntary, they cannot be practiced, and they are not affected by drinker tolerance.
520 # $a Multiple, extensive research projects sponsored by the National Highway Traffic Safety Administration (NHTSA) have shown HGN to be the most reliable and accurate, scientifically validated field sobriety test. Despite these results and an enthusiastic embracement by the law enforcement community, testimony about HGN is not permitted by a majority of Virginia trial judges. The purpose of this study was to examine, as suggested by the literature, several possible impediments to the introduction of HGN, and to determine the degree of impact these factors have on judicial attitudes regarding admissibility of the test in Virginia DUI trials.
520 # $a One hundred and three Virginia general district court judges completed a 27-question survey. Responses from HGN proponents and opponents were compared using cross tabulations. Clear differences between these judges were noted; low significance values (<.05) on Chi-square tests suggested that there might be a relationship between the criterion variable and 17 of the 20 predictor variables. Logistic regression was used in the primary multivariate analyses to determine how well certain variables predicted the known outcome (i.e. whether or not the judges accept the horizontal gaze nystagmus test). Results indicated that judges who do not permit HGN testimony consider the test to be “scientific” in nature, requiring the laying of a scientific foundation by an expert witness. Furthermore, HGN opponents had strong reservations about the ability of police officers to properly administer and interpret test results or to qualify as experts.
520 # $a Several policy recommendations were made to improve the acceptance rate of the HGN test in Virginia courtrooms, the most notable being calls for an overhaul of the HGN training and certification process for police officers and increased education for judges and prosecutors.
