47 Types of Nystagmus

47 types of nystagmus

The horizontal gaze nystagmus (HGN) test is the eye test that police officers use to determine if you are intoxicated.  San Antonio DWI lawyer Jamie Balagia, at our law office have been trained in the administration and interpretation of the HGN as part of their Standardized Field Sobriety Test training.  The problem with the HGN test is that there are many forms of nystagmus, and police officers are not trained to tell the difference between the various types.  If you have been arrested for a DWI in Texas contact our office now for a free, confidential consultation.
