Nearly all DUI cases tried in court will include some testimony regarding field sobriety testing (hereinafter "FST"). FST’s such as the One Leg Stand, Walk and Turn and Horizontal Gaze Nystagmus (Eye Test) have gained prominence in recent years as seemingly effective, objective, easy to administer methods of determining impairment. Without adequate training, these tests are presented by the prosecution in court, with one goal in mind. To obtain a conviction! Unless these tests are subject to exacting scrutiny by defense lawyers, a jury may be swayed by their "objective and scientific" nature. Indeed, at first glance, the FST’s seem simple enough for some sober people to perform. It is a defense lawyers duty to demonstrate that these initial observations are not always as conclusive as one might think. The single best way to call these evaluations into doubt is by knowing how these FST’s work and through a thorough and well prepared cross examination. George Stein is trained and certified in field sobriety testing. He is a frequent lecturer on the subject. His advanced training gives him the advantage when it comes to cross examining the arresting officer at trial.
