The Workings of the Breathalyzer

The portable breath analyzer is typically the first test administered in a possible DWI case. It works by chemically testing for the blood alcohol content, or BAC from a breath sample. Even if a person brushes or rinses his or her mouth, the breath, which originates from the lungs is still contaminated since alcohol in the blood is released through the lung cells. On the other hand, however, recent partaking of alcohol even in a small legal dose, leaves alcohol in the mouth and throat which can give a faulty high result. This leaves a certain ambiguity to the test and may become a basis of false arrest or charging. That is why there are other sobriety test that need to be administered before charging can legally apply.
