Understanding DUI Laws and the DUI Breath Analysis Test

By Cary Bergeron

When you are pulled over on suspicion of driving under the influence of alcohol (DUI), you will likely be asked to submit to a breath analysis test. Understanding this test is essential if you are going to decide whether or not to take it. Refusing to take the test can be used against you in court in many states, so make sure you understand how it is used.

First, in order to understand the breath analysis test, you must first understand how the body reacts to alcohol. Alcohol enters the blood stream quickly because it does so through the walls of the stomach, rather than needing to travel through the entire digestive system. Bodily fluids dilute the level of the alcohol in the blood, and some is eliminated through the liver. Whatever is left in the blood is excreted through sweat, urine, and the breath of the drunken individual. The breath analysis test is done in an attempt to measure the BAC of the individual through his or her breath.

The breath analysis is done using a machine known as a Breathalyzer. This machine is simple to use. You simply breathe into the Breathalyzer, and it will show the police officer your BAC. These results are not perfect, but they are an indication of whether or not you are driving with a BAC that is above the legal limit in your state. If you fail the test, you will be brought in for further testing, including a possible blood or urine BAC test.

Many states allow the breath analysis test to be used against you in court. However, if you are working with an attorney, your attorney may be able to prove that your test results were inaccurate. Many factors can distort the results of the Breathalyzer test, so if your test results were extremely high, or if you felt they were inaccurate, consider working with an attorney when you head to court.

The Breathalyzer is an important tool to officers who actively search for drunk drivers. It gives them yet another simple way to determine whether or not an individual is driving with too much alcohol in his or her system. Before you decide to sit behind the wheel of a car after having a few too many drinks, remember that the police officer who catches you will have a quick and easy method to determine if you are drunk, and drunk driving carries swift and heavy consequences, no matter which state you are calling home.
