Breath Testing for Prosecutors is a 351 KB document written by Jeanne Swartz in 2004 for the American Prosecutors Research Institute. This document tells you how alcohol breath testers actually work. It explains the history and the problems of false fail readings. There is a difference between mouth alcohol and deep lung alcohol. Alcohol in your mouth evaporates quickly but various foods and drinks taken 15 minutes before a breath test can make a difference.
This document explodes many of the myths about these breath test devices. It is well researched and is easy for the driver to understand. It explains why 0.08 mg/ltr is used as a goal post by
National Express rather than the legal limit of 0.35 mg/ltr. This is a good and informative read for all drivers who use vehicles fitted with
alcohol breath test devices .
