Breath Tests & Blood Tests Attorneys

Helping People In Austin & Surrounding Areas

When you are stopped for a DWI, the arresting officer will usually administer a breath or blood test to determine your intoxication level. The results of these tests will be used to build the prosecution’s case against you. If you were arrested for a DWI and submitted to a breath or blood test, you should immediately speak with our attorneys to discuss your legal options.

Breath Tests

In Texas, police officers use an outdated machine called the Intoxilyzer 5000 to administer a breath test on a DWI suspect. Although most other states have upgraded to using more accurate equipment, Texas remains behind the curve and continues to use this problematic machine.

In order to get a DWI conviction the State must prove beyond a reasonable doubt that you were intoxicated at the time you were driving. If your breath test results are .08 or above, you’ll need an attorney to show the jury how unreliable the machine actually is.

Don’t think that all hope is gone because you blew above .08. The breath test is just one piece of evidence and the burden to prove that you were intoxicated can be difficult to meet. Our lawyers will review your case to determine if there was reasonable suspicion or probable cause for your traffic stop. We will also challenge the breath test procedures used by the arresting officer.

Blood Tests

Although you have the constitutional right to refuse a blood test, doing so can result in your license being suspended. Your refusal can also be used as evidence against you in court. If you are arrested during one of Texas’ “no refusal weekends,” you can still refuse a blood test. Furthermore, police will need a warrant from a judge to draw your blood after you refuse.

The following factors can affect the validity of a blood test:

  • Did the police have a lawful warrant?
  • Was your blood drawn in a sanitary environment?
  • Was there a proper chain of custody regarding the blood?

A DWI conviction can be devastating to your personal and professional life. If you have been arrested for DWI, do not wait to contact an attorney.
