Yesterday, we discussed Standardized Field Sobriety Tests and the non-standard Field Sobriety tests. Begining in 1975, the National Highway Traffic Safety Administration (NHTSA) began reviewing the field sobriety tests. After an extensive, exhaustive study for TWO YEARS, NHTSA determined that only three tests were determined to be reliable. That is, whether there was a good correlation with impairment when the three are used together. These three have become the
Standardized Field Sobriety Tests and they are (1) the HGN; (2) the walk-and-turn; and (3) the one leg stand.
The key to these tests is that they have to be administered in strict adherence to the guidelines and parameters set by NHTSA. The tests need to be administered, every time, in the same way. The officers need to look for a specific set of clues on each performance. Also, the administer of the test must evaluate the performance in comparison specific criteria each time.
