Toxicology Issues

Drunk Driving Defense Lawyers Challenging Breath Test Results in DUI or DWI Cases

DUI lawyer for toxicology issues throughout Alabama

The DUI focused law offices of Parkman White, LLP in Birmingham are concentrated on DUI defense throughout Alabama.  As a result, we have gained a great deal of experience and technical familiarity with the Draegar Alcotest 7110 breath analysis device used by Alabama law enforcement agencies.  As one of the only offices with a lawyer who has been certified on the Draegar Alcotest 7110, our Birmingham DUI office can provide unique insight.

This experience helps our trial lawyers make effective presentations at jury trials whenever defects in the operation or maintenance of the Draeger raise questions as to your correct blood alcohol concentration.  Contact us today at 205-502-2000 to schedule an appointment with one of our three DUI defense offices.

Breathalyzer and other devices for determining BAC are not always accurate.

A blood alcohol reading of .08 or greater will usually support a conviction on most DUI charges in Alabama. For commercial drivers, the level may be no more than .04. For underage drivers, a blood alcohol concentration as low as .02 can lead to conviction.

If your DUI case involves a reading substantially higher than any of these minimum thresholds, a defense based on toxicology probably won’t be as effective as it will when the reading is closer to the minimum. Whenever our cross-examination shows that the law enforcement officer who conducted your breath test didn’t understand how to do it properly, however, you stand a good chance of ruining the government’s ability to prove its case beyond a reasonable doubt.

Because we handle all phases of your DUI defense for a single flat fee, we can advise you about your ability to present a strong defense based on mistakes in the breath test.

Lots of things can go wrong with a Draeger breath test or other breathalyzer—operator error, lack of operator certification, even radio interference or diet-related mouth alcohol.
