Breath Tests & Blood Test Charged With DWI? Protect Your License Before Time Runs Out

DWI Breath Tests & Blood Tests

San Antonio DWI Attorneys

DWI breath or blood tests are used by law enforcement to gauge your level of intoxication. Their results are then forwarded to the prosecutor to be used against you in court. If you have been arrested for a DWI in or around San Antonio based on a breath or blood test, you should seek immediate legal help from one of our capable attorneys to have your case reviewed.

Breath Tests

At this time, the Intoxilyzer 5000 is the machine used by Texas law enforcement for testing intoxication levels on a DWI suspect. This machine is outdated and considered by many to be unreliable. Many other states have progressed to more advanced equipment but Texas has not.

In a DWI case, the prosecutor must prove beyond a reasonable doubt that your driving was impaired. A breath test measuring .08 or above can provide proof unless your attorney challenges the unreliability of the Intoxilyzer 5000.

Just because you blew above .08 does not necessarily mean that your case is lost. A breath test is only part of the prosecutor’s case. He or she will be obligated to prove to the jury that you drove while intoxicated, which can be a difficult task. Our San Antonio DWI lawyers will fully investigate your case to determine the basis for your traffic stop and whether it was justified. Challenging the breath test will also be part of our defense strategy.

Blood Tests

In DWI cases, you have the legal right to refuse a blood test. By doing so, however, you will face an automatic license suspension. Refusing to submit to a blood test can also be used against you in court. You can even refuse to submit to a blood test during a “no-refusal weekend,” in which Texas engages. Once you refuse, law enforcement will have to obtain a warrant from a judge in order to have a blood test administered.

When challenging a blood test’s validity, we ask:

  • Was a lawful warrant obtained by law enforcement?
  • Was the blood test conducted in a sanitary environment?
  • Was a proper chain of custody maintained in regards to the blood?

Our firm can thoroughly investigate all of the factors regarding both breath and blood tests that can negatively affect the prosecution’s case. We know what to look for and how to use what we find when it comes to defending you in a Texas DWI.
