When an officer pulls a suspected drunk driver over during a traffic stop,
he or she may ask the driver to take a roadside breath test. Since most
states, including Arizona, have an implied consent law, refusing a BAC
test could result in an automatic license suspension. But are these tests
even an accurate way to measure BAC? Unfortunately, they are not.
Why Breath Tests are Unreliable
Breath tests can be performed on the road during a traffic stop or at a
police station after an arrest. The breathalyzer involves blowing into
a machine that analyzes how much alcohol is contained in your breath.
This is a very indirect method of determining BAC, as the results are
not based on how much alcohol is actually in the body. Depending on body
temperature and respiration rate, the results of the test can easily be skewed.
Additionally, there are a number of other factors that could throw off
the results of a breath test. Certain mouthwashes, breath fresheners,
and toothache medicines, or any other substance containing alcohol, could
cause an inaccurate reading. Even a burp or regurgitation of stomach acid
just prior to or during the test can skew results.
This is not to mention the problem of maintenance. Breathalyzer machines
must be routinely maintained and calibrated to keep them accurate, but
many times they are not. If a breath testing machine malfunctions, it
could result in a false-positive reading, and as a consequence you could
face penalties that you may not even deserve.
