them were alcohol related. In fact, those same statistics show that those who are given roadside sobriety tests may still be too drunk to drive and the only reliable way
to test the level of alcohol in a persons system is through the use of the Breathalyzer (Freudenrich, 2002). But are they as accurate as the public is led to
believe and do they work for everyone? The measuring device used by most law enforcement officers is the breathalyzer. This device is able to measure the blood alcohol level or
BAC in a person, without having to take an actual blood sample to a laboratory. This breathalyzer is built on the premise that alcohol is not readily digested upon absorption
by the body. Dr. Freudenrich states, "Alcohol is not digested upon absorption, nor chemically changed in the bloodstream. As the blood goes through the lungs, some of the alcohol moves
across the membranes of the lungs air sacs (alveoli) into the air, because alcohol will evaporate from a solution -- that is, it is volatile" (Freudenrich, 2002). In other words,
the amount of alcohol that is found in the air from the lungs is related to the amount of actual alcohol in the blood. Actually, there are quite
a few different models that are used by law enforcement officials today. One device utilized infrared rays, another uses fuel cells, and the most popular model utilizes a chemical reaction
with a color change (Freudenrich, 2002). Since this is a scientific piece of equipment, the officer must receive training on the calibration and maintenance of it in order to be
able to be admissible in a court case involving a DUI (Driving Under the Influence) charge. The Journal of Forensic Science stated that the overall accuracy of the Breathalyzer in
