Criminal defense attorney Katie Gonos attended a seminar on DUI Detection & Standardized Field Sobriety Testing using the current National Highway Traffic Safety Administration manual, which is currently used by law enforcement. The seminar focused on the three field sobriety tests used by law enforcement including the HGN test, the One Leg Stand, and the Walk and Turn test. The participants studied the proper procedures in conducting the tests and the mistakes that are often made by law enforcement. They were then asked to perform the field sobriety tests on test subjects. Part of the training involved a full day course on the Intoxilyzer 9000. Georgia currently uses the Intoxilyzer 5000, but all municipalities and counties will have the Intoxilyzer 9000 by 2015. The participants studied the differences between the two instruments and learned how to interpret test results.
