It is important to understand that in all drunk driving cases, the State must prove that the accused' blood alcohol level or concentration at the time of the offense was at or above the statutory limit. In Texas that limit is .08. It is necessary to obtain a suitable sample of the person arrested for drunk driving in order to prove the level of alcohol in the blood is above statutory limits at the time of the arrest. The use of a breath test is the most common method for the State to prove that a drunk driving offense has actually occurred. Many defendants, however, have been able to effectively dispute the outcome and results of the breath tests in court. Therefore the State is unable to obtain the conviction. Carabin and Shaw, P.C. associates are experienced in drunk driving defense law and can advise you on whether the "Breathalyzer" test results may be subject to challenge in your particular case.

Test Results Can Be Challenged on Several Bases

Variables that can lead to questionable results include:

• skill and experience of the tester
• quality of equipment used
• exposure of the accused to paint or gasoline fumes or dry cleaning fluids 
• the temperature,
• atmospheric pressure,
• the chemical composition of the alleged offender's blood,
• his or her physical activity,
• hyperventilation

Texas Courts have allowed drunk driving defendants to present expert testimony of the scientific inaccuracy of Breathalyzer test results based on these inherent variables. Some courts have demonstrated more willingness than others to accept challenges to blood alcohol test results. As an experienced drunk driving attorneys, Carabin and Shaw, P.C. knows which challenges are likely to be accepted in local courts and which are not. It is important to remember that even if you have blown an above-the-limit reading on a Breathalyzer test you may not be convicted of DWI. Carabin and Shaw, P.C. associates are skilled and knowledgeable lawyers able to explain what challenges are appropriate to your particular case and possibly even keep the test results out of court entirely.
