The federal government has done a series of studies to determine what are the most reliable of the field sobriety tests. And they have come up with three, and they're called the standardized field sobriety tests. The first standardized field sobriety test is the horizontal gaze nystagmus test. That's where you're asked to follow a stimulus with your eyes, and the officer looks to see if you have a nystagmus, which is an involuntary jerking of the pupil which is associated with impairment. The second standardized field sobriety test is the walk and turn test. That's where you're asked to walk a line, nine steps in each direction. And the third of these standardized field sobriety tests is the one-leg stand test, where you're asked to lift one foot off the ground and hold it there for 30 seconds.
