Are Georgia breathalyzer tests legal?

Most DUI arrests are followed by a request for the driver to submit to a Georgia DUI breath test to determine the driver’s breath alcohol level, which is an indirect attempt to estimate blood alcohol content. From 1995 to 2015, the breath machine used in Georgia has been the Intoxilyzer 5000 made by CMI of Owensboro, KY.

A new device, the Intoxilyzer 9000 (also made by CMI) also has been approved for use in Georgia since 2013, and will become the sole approved forensic breath testing device that can be used in this State January 1, 2016 and after. So, an arrest for driving under the influence of alcohol will usually require the driver to take or refuse to take the official breathalyzer machine test, as used in GA. Then, the DUI per se case for being over the legal limit would move forward against the accused drunk driver.

Despite ALL breath test devices used in the USA having fully automated, computerized processors and a sortable database that is capable of retrieving and storing full operational information, the GBI in GA never bother to purchase any software to use with the Intoxilyzer 5000. So, no downloads of the all-important data proving reliability NEVER happened. The GBI did this intentionally, so that criminal defense lawyers fighting DUI cases with breath tests involved could not see if the device was working correctly when their client’s Georgia DUI breath tests were collected.

In addition to this attempt to hide information from criminal defense attorneys representing accused drunk drivers, the GBI was extremely careless in approving a forensic device without ever CHECKING the source code for errors in the many functions that the Intoxilyzer 5000 must run to give a valid test. The breath machines were bought on face value, with NO meaningful verification of the breathalyzer test device’s accuracy and precision. Moreover, the GBI bought the Intoxilyzer 5000 without even an archive copy of the breath test source code, in case the manufacturer went out of business and software upgrades were needed.
