Department of Justice Expands Training for DUI Enforcement
HELENA – About 400 people are expected to take part in horizontal gaze nystagmus (HGN) training this week in Billings, Helena and Missoula. Participants in the training include law enforcement officers, prosecutors, judges and others.
“Training in HGN will enable us to improve our DUI enforcement efforts,” Attorney General Mike McGrath said. “We hope to substantially improve the effectiveness of our field testing efforts.”
Nystagmus is an involuntary jerking of the eyeballs that becomes outwardly visible when a subject drinks. HGN testing is one component of a field sobriety test used to evaluate an impaired or drunk driver. In a typical HGN test, a stimulus — the end of a pen or a flashlight, for example — is positioned slightly above eye level. The stimulus is moved horizontally in front of a subject and the tester watches for specific characteristics as the eyes move.
Dr. Karl Citek, a professor at the Pacific University College of Optometry in Forest Grove, Ore., will lead the training. Citek holds a Ph.D. in vision science and a degree in optometry. He has testified as an expert witness in cases in Idaho, Oregon, Kansas, Washington and Hawaii and has done presentations on gaze nystagmus around the Northwest.
At each workshop, Citek’s presentation will be from 1 to 5 p.m.
