For drivers in Arizona, the thought of being investigated on suspicion of drunk driving is a daunting one. All of a sudden, you find yourself at risk of a life-changing conviction. You could be fined, lose your license or even be sentenced to time in prison. Your record is permanently stained and this in turn can affect your future prospects. The whole ordeal could even cost you your job and put a strain on your family life.

One of the common ways people end up being charged with drunk driving is by failing a breath test. If your BAC is found to be equal to or in excess of 0.08 percent, you are legally considered to be intoxicated, regardless of how much or little you appear to have been affected by the alcohol.

Unfortunately, these tests are not always entirely accurate and this can result in innocent people being charged for a crime they did not commit. Fortunately, if you feel that the evidence from a breath test you have undergone is flawed, you can appeal the matter and this could be beneficial to your case.

According to this article on DUI charges, studies suggest that the results of a breath test carried out via a Breathalyzer can err by up to as much as 15 percent. This was determined by comparing results with those ascertained via blood draw. It is a worrying fact as this could be enough to move your result from a pass to a failure.

Fortunately, if you find yourself in this situation, an attorney may be able to help. He or she can advise you on how best to challenge the results of your breath test and may be able to suggest other steps you can take to further strengthen your defense.
