Texas DWI Breath Test


Texas law enforcement employs numerous tests to help quickly identify intoxicated drivers. The Breathalyzer and machines like it require a sample of the driver’s breath. Using this, the machine can determine the driver’s Blood Alcohol Content (BAC). In Texas, driving with a BAC level of .08 or higher will yield a DWI charge. However, a qualified DWI lawyer like Ken Gibson can defend these charges with the right knowledge. Let’s study more about these breath tests and learn how they are defended.

An Array of Breath Analysis Machines

Breathalyzer is actually just one brand of breath testing device. It’s just so well known it become a name for all similar machines. Other breath analyzers include Alcosensor, AlcoMate, and Intoximeter. Police use two different types of breathalyzers. One is hand-held and used by officers on the road as a preliminary field sobriety test. They are not as accurate, but can be used as a field sobriety test to get an idea of BAC before taking them to the station for a standard breath test. The other is the breathalyzer used in police stations, which utilizes infrared spectrophotometer technology. This type of technology is generally more reliable than the hand-held fuel cell analysis.

Ok, Ok…Spare the Boring Scientific Explanations! How Do I Defend My Breath Test Results??

As with any form of analysis there are numerous chances for error. In fact, the results are entirely dependent on the ad minister’s competence and compliance with test procedure. Air temperature, subject temperature, and pre-existing conditions can alter test results. In addition, any breath analyzer must be calibrated regularly. Even if a breath test was administered correctly and the machine was working properly there may still be a 20% margin of error. This is clearly large enough to mean the difference between innocence and guilt. It may not seem like much of a difference to the prosecution, but to the individual whose life is at stake it can mean everything.
