Horizontal Gaze Nystagmus

Nystagmus refers to the involuntary jerking movement of the pupil. While nystagmus occurs because of alcohol consumption, there are other cause which would cause such a condition. The HGN (Horizontal Gaze Nystagmus) test is usually given first by police officers in Rhode Island. They will tell you to stand still, feet together, with your hands down by your side. The office will tell you to keep your head still and follow the tip of his pen (held out 12 inches from your face) with your eyes. There are three “clues” the officer looks for as signs of intoxication due to nystagmus. A skilled Rhode Island DUI Defense Lawyer will know the “ins” and “outs” of this condition and how it does and does not translate into evidence of intoxication.
