Georgia DUI – Intoxilyzer 9000 – Selection Report

If you have been charged with DUI in Georgia and you submitted to the requested state-administered breath test, you probably were tested on an Intoxilyzer 9000. For some reason, many people mistakenly believed that the “new” Intoxilyzer 9000 was an improvement over the Intoxilyzer 5000. The evaluation that the Georgia Bureau of Investigation (“GBI”) performed upon the Intoxilyzer 9000 and two (2) other machines prior to implementation of the Intoxilyzer 9000 as the breath testing machine draws into question this assumption. If your DUI lawyer is knowledgeable about this report, there is some fantastic data that can be used to illustrate doubts as to the reliability of the breath test device used in the prosecution of your Georgia DUI case.
