- The police officers commonly use roadside field sobriety tests ("FSTs") in DUI investigations in order to determine whether a driver is under the influence of alcohol. Typically, these tests consist of a battery of 3-5 excercises, such as walk-and turn, one-leg stand, "nystagmus" ("follow the pencil with your eyes"), finger-to-nose, alphabet recitation, "Rohmberg" (eyes-closed-position-of-attention), etc. It may be subjectively decided by the officer that whether the individual "failed", or the officer may decide it after applying recent federal "standardized" scoring.
These DUI tests possess an aura of scientific credibility. Unluckily, despite of all the facts, these tests have no real basis in science and they are almost useless in a drunk driving case.
First, as it is known by any traffic officer or DUI attorney that the decision to arrest is made at the driver’s window; the FSTs that are given are supposedly to determine probable cause to arrest. These tests are actually taken for the purpose of gathering evidence.
