The Horizontal Gaze Nystagmus Test & DUI Charges
DUI Arrests Caused By False-Positives
The HGN test is one of the three
field sobriety tests that Connecticut law enforcement officials use when conducting a DUI investigation.
During this test, police officers look for an involuntary movement of
the eye that can be caused by alcohol consumption or certain types of
drugs. While this test may sometimes be accurate in determining whether
or not an individual is under the influence, the studies surrounding HGN
testing have not been done rigorously and many false-positives result
due to a variety of other factors.
Aside from alcohol consumption, HGN can also be caused by:
- Certain medical conditions

How Is the Test Administered?
The HGN test is supposed to be given in a standardized manner by police
officers while you are standing outside of your vehicle. First, they will
ask you to remove your glasses and keep your head still as you follow
the stimulus with your eyes only. The stimulus could be an object such
as a finger, pen or pen light that is held approximately 12 to 15 inches
away from your face. It is held slightly above eye level as they move
it from a standard position to the right, back to the center, and then
to the left.
