Breath Alcohol Tests
A breath alcohol test, commonly called a "breathalyzer" or a "BAT", is an instant screening that determines precisely how much alcohol a person has in their breath. Relying on a scientific principle known as "Henry's Law", the percent of alcohol in a person's breath can be assumed to match the percent of alcohol in that person's blood. As compared with blood alcohol tests, breath testing for alcohol is far more convenient, less painful, much faster, and just as accurate. Thus, breath alcohol testing has become the most popular method to detect if someone is intoxicated, and is widely used by employers, required by DOT, and administered by law enforcement.
