We've all seen field sobriety tests being carried out on television or in the movies, but how many of us have actually been subjected to one? If you're reading this article, you may have been accused of a DUI and you might not be certain if the police carried out your field sobriety test appropriately. In some cases, if the police violated standard procedure and regulations when performing a field sobriety test, you might be able to get the evidence form the test thrown out of court.
Here's what a standard field sobriety test entails:
Horizontal gaze test: The "Horizontal Gaze Nystagmus" test looks at the way an intoxicated person's eyes will jerk when they move from right to left. There's no way to fake your way through this test, and an officer will look for three different indicators while performing it: (1) jerking eye movement when the eye has moved to the maximum of left or right; (2) jerking eye movements when moving the eyes from left to right; and (3) jerking eye movements when the eyes are at 45 degrees of the center.
The walk and turn test: The walk and turn test involves walking heel to toe in a straight line, turning on one foot and coming back.
One-legged stand test: The one-legged stand test simply requires you to hold one of your feet approximately six inches from the ground while holding steady.
Scientific testing has revealed that the above three parts of the field sobriety test can predict intoxication in approximately 91 percent of cases. That being said, in order to for the field sobriety test results to be accurate, they need to be administered in the right way. If you suspect that the police did not conduct your DUI tests appropriately, talk to your criminal defense attorney about it as this could be an important point to bring up during your defense.
