IMPROVED SOBRIETY TESTING

The purpose of this Manual is to acquaint you with the most effective procedures for testing drivers at roadside to determine whether or not they are intoxicated. Police officers generally evaluate a driver's physical appearance and condition while he is still seated in the vehicle. This evaluation typically includes: 1) breath odor; 2) condition of the eyes; 3) demeanor; 4) color of the face; 5) dexterity; 6) speech; and 7) clothing. Further testing is usually given only if these preliminary evaluations cause the officer to be suspicious. The sobriety tests contained in this training program were selected from those used by police officers throughout the country and were refined by research scientists to make them as reliable as possible in determining alcohol intoxication. The testing and scoring procedures were standardized and the tests were evaluated in the laboratory and in the field. Although these tests are not meant to replace other tools, careful testing and scoring in accordance with the procedures outlined in this Manual will enable officers to determine the blood alcohol concentrations of 0.10 percent or more at roadside. To assist officers in the learning and practice of these testing techniques, a video tape has been prepared which explains and illustrates the tests. The last part of this tape consists of practice segments in which viewers, using the score sheets at the back of this Manual, may evaluate the performance of intoxicated volunteers. In addition, the Manual explains proper testing, scoring, and decision criteria of the tests so that the material may be studied and reviewed periodically.
