Texas DUI Defense Attorney Discusses the Role of Science in DUI Cases

One of the most important elements of a strong DUI defense case is science. While some of the evidence that is involved in DUI cases is circumstantial, such as things that police officers claim that the driver said or did, other important pieces of evidence are scientific. Texas DUI defense attorneys know that understanding the scientific principles that relate to things like blood and breath tests can make or break a DUI defense case, as can knowing how to bring challenges against scientific evidence in court.

Evidentiary challenges have helped many DUI defendants avoid convictions, and they may play a role in your DUI case. There are many ways to challenge blood and breath test evidence. From the manner in which the samples are collected to the equipment that is used and what happens to the sample after it is collected, there are multiple points in time at which things happen that can form the basis for an evidentiary challenge. For example, law enforcement officers may not use the testing equipment properly, due to insufficient training, lack of experience, or mistakes. Equipment that is used may be outdated. Samples can become contaminated or be mishandled. In short, there is a lot of room for error, and DUI defense attorneys are experienced at examining the course of events that occurred during and after a DUI traffic stop in a way that often enables them to find one or more bases for challenging the blood or breath testing evidence.

If a driver who has been charged with DUI chose to participate in field sobriety testing, there are often ways to challenge evidence that is related to those tests. There is a growing body of evidence that supports a conclusion that field sobriety tests do not provide accurate information, so it is a good idea to challenge them on that basis.

There are also other ways in which science is relevant to DUI defense. Medications, metabolism, food and drinks can all interfere with the accuracy of blood and breath test results. The natural differences between all of our bodies can also affect test results because weight, gender, and body structure all influence how alcohol affects us.  A knowledge of the science that is involved in how alcohol works in our bodies can help DUI defense attorneys formulate other challenges to DUI charges if they are applicable to an individual’s situation.

If you have been charged with driving under the influence of alcohol, you need a strong ally who can help you defend yourself against DUI charges.
