Chicago DUI Trial Attorneys are well aware that the three non-chemical Field Sobriety Tests that have been standardized by the U.S. NHTSA doe DUI for cannot accurately determine your driving impairment. Research scientists have stated that there is not even a single study to validly link the standardized Field Sobriety Tests to the level of your driving impairment.
The U.S. NHTSA, the U.S. Department of Transportation, and NHTSA-commissioned researchers advise that the standardized Field Sobriety Tests do not provide actual direct indicators of your driving impairment. These agencies and researchers advise that driving a motor vehicle is actually a very complex activity that involves a wide variety of tasks and operator capabilities and it's unlikely that complex human performance, such as that required to safely drive an automobile, can be measured at roadside in a Field Sobriety Test. Your Illinois DUI Defense can use these agencies statements on the issue to help your case.
An able Illinois DUI Defense will point out that DUI Field Sobriety Tests are largely coordination tests. Three of the most common tests are the Walk and Turn Test, the One Leg Stand Test, and the Finger-to-Nose Test. On these tests, the officer that stops you on suspicion of DUI will generally ask you to take one or more of the Field Sobriety Tests. Besides the three tests standardized by the NHTSA, there are also non-standardized tests that vary from location to location.
The officer will generally ask you to take a few Field Sobriety Tests and then will report that you failed each test. The officer will administer the tests at the scene of the location where he or she pulled you over or came to investigate your crash. More often the not, your Chicago DUI Trial Attorney's investigation will find that the lighting and road conditions might be poor, and when you perform the tests you will be under stress from being pulled over or having an accident.
An experienced Chicago DUI Trial Attorney will caution that if you fail one or more of your Field Sobriety Tests according to the Arresting Officer, then your Illinois DUI Defense lawyer could attempt to create a reasonable doubt about the tests in the minds of the jurors by pointing out the conditions under which the tests were given, the subjective nature of the tests, the inaccuracy of the tests for determining actual blood alcohol level, and the inherent difficulty of some of the tests.
Your Chicago DUI Trial Attorney might carefully cross-examine the Arresting Officer regarding how many of the tests you failed. If your "failed" them all, your Illinois DUI Defense lawyer might ask if the officer was "expecting" you to fail and if that clouded his judgment in subjectively scoring your test. After all, the officer is the only one present to grade your test performance, and if he or she pulled you over, the officer might be already predisposed to see you as DUI.
These careful, subtle questions from your Illinois DUI Defense lawyer point out that Field Sobriety Tests are very subjective measures of person's intoxication level and that the Arresting Officer is likely to read into the test what he wants the results to be. Your Chicago DUI Trial Attorney's cross-examination of the Arresting Officer is particularly significant because it is the first real confrontation between the prosecution and your defense in front of the jury.
