  Kansas DUI Field Sobriety Test
Field sobriety tests are "psycho physical" tests - "Psycho" as in mental, and "physical" as in coordination.
The Horizontal Gaze Nystagmus Test: This is a test where the officer holds a pen or similar object in front of the subject's eyes to determine whether she can follow it.
While many police officers feel that this is the most reliable field test they have in their arsenal, it is not allowed in court unless the prosecutor has an expert witness to testify to its scientific validity.

 Field Sobriety Test
Often misunderstood field sobriety testing is used by police officers to establish probable clause to arrest a potential suspect for driving while intoxicated to administer a breathalyzer to determine whether a per se violation (.10 BAC) has occurred.
Thus, the examination and understanding of field sobriety testing is of paramount importance because the defendant must not only defeat the breath test result but also the officers subjective interpretation of the field sobriety tests.
The walk and turn test is required to be performed on a hard, dry, level, non-slippery surface, preferably with a straight line clearly marked on the ground and sufficient room for the individual to perform at least nine heel-to-toe steps.

 Field Sobriety Test   (Site not responding. Last check: 2007-10-24)
These three "standardized" tests (SFSTs) are the "Walk and Turn" test, the "One-leg Stand" and "Horizontal Gaze Nystagmus" in which a law enforcement officer observes the discrete movements of a person's eyes when tracking a stimulus across their field of vision.
Chemical tests are better at determining the driver's BAC than they are at estimating the level of impairment, but their accuracy is disputed by some (see blood alcohol test assumptions).
In any case, tests can only determine the BAC at the time the test is taken, which sometimes can be higher than when the vehicle was actually operated, in the case of a driver who drank a large volume immediately before driving.

 Field Sobriety Tests
These are not really tests at all; rather, I like to think of them as Roadside Agility Exercises that are highly subjective in nature, and designed for failure.In theory, these tests were designed to simulate and evaluate your "divided attention" abilities, a critical skill in operating a motor vehicle.
In deciding whether to submit to these exercises, you should know these tests are highly subjective and only 3 have been "standardized" and "validated" as "acceptable" in the "scientific" community, while the remaining exercises are even more unreliable and unsupported as accurate for the detection of alcohol impairment.
It is important to understand, the officer is supposed to advise you this test is voluntary and not the one required by the Implied Consent Law, however, most of the time this is forgotten, in order to secure more evidence of your impairment and/or breath alcohol level.

 Georgia Field Sobriety DUI DWI Test
These tests, known as the “standardized field sobriety tests” [SFSTs], were designed pursuant to numerous federal grants and ultimately sanctioned by NHTSA (the National Highway Traffic and Safety Administration) beginning in 1984.
Tests given by some officers may have included reciting the alphabet (or a portion thereof), picking up coins off the ground, or touching index fingers to the tip of the nose while the person’s eyes were closed and head tilted back.
The Supreme Court of Ohio recently held that the officer’s failure to fol­low NHTSA training in administering field sobriety exercises was a factor in determining the admissibility of the test.
