Horizontal Gaze Nystagmus (HGN) Test

How HGN (Eye) Tests Work

When performing this test, an officer is looking for a nystagmus in your eyes, which is a formal way of saying that they want to see if your eyes will twitch, a potential sign of intoxication. During the HGN test, an officer will tell you to not move your head, and they will hold out something like a penlight for you to follow with your eyes. As you follow the light, the officer is looking to see if your gaze jerks along the way, or if your eyes twitch at a 45-degree angle. In fact, there are six such signs in total, and four such "clues" are enough to lead to a DUI arrest.

The bad news: if and only if every part of the HGN test is properly followed, the test is known to be reliable 77 to 88 percent of the time, powerful evidence in the hands of a prosecutor. Even so, tests are not infallible, and there are many possible reasons that a test result is misleading. This is the case when an officer fails to properly give the test, if you have an eye or neurological condition, etc.
