One Defense to Breath Alcohol DUI Cases

One defense to breath alcohol DUI cases is the condition of the mouth cavity. Under Tennessee DUI law, a police officer must watch you for 20 minutes prior to the breath alcohol test. The reason is to make sure the mouth alcohol has dissipated from the mouth and you do not burp, hiccup, or regurgitate. The presence of mouth alcohol can influence the breath test result. What else can influence a reading of mouth alcohol?

Why the Police Take Two Breath Test Samples ?

There are two types of tests used to measure blood alcohol tests in the State of Tennessee. First, a blood sample can be obtained. Second, a breath test can be used. Metro Nashville Davidson County police still rely on using the breath alcohol test. In fact, mobile breath test machines are in the police cars of the DUI unit. A different type of breath alcohol machine is located in the booking room of the Criminal Justice Center.
