Breathalyzer DUI Blood Alchohol Test

The Breathalyzer is the most commonly used device for determining one’s Blood Alcohol Content (BAC) from a breath sample.  The Breathalyzer test is usually administered after one is arrested and charged with Driving Under the Influence (DUI), at the jail or police station. If you are licensed to drive in the State of Georgia, you impliedly consent to a chemical test of your blood, breath or urine at the request of a police officer.  Refusal to submit to these tests can subject you to an administrative prosecution and a minimum of one (1) year suspension of your license.

The machine currently used in Georgia to administer these chemical tests is the Intoxilyzer 5000.  This is a big typewriter-size machine in the jail or police station in which breath samples are taken from a subject, analyzed, and one’s BAC (Blood Alcohol Content) is calculated in grams.  While the Breathalyzer, when properly calibrated and administered, can provide a fairly accurate indication of one’s blood alcohol content, it far from perfect.  There are numerous design flaws inherent in the machine, and many physical and environmental factors and conditions (such as acid reflux, mints, gum, and mouthwash) can affect the reading.
