Breath Tests & Blood Tests Boldly Defending Your Best Interests

Breath and Blood Test Attorney Austin, TX

Representation From DWI Test Attorneys in Austin

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 Austin DWI attorneys to discuss your legal options.

Texas BAC 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In Texas, police officers use an outdated machine called the Intoxilyzer 5000 to administer a breath test on a DWI suspect.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 Austin breath & blood tests 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 Austin DWI 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.

Texas BAC 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 Austin breath & blood tests attorney.

      Our client was arrested for her fourth DWI with an alleged BAC of 0.168. The State aggressively prosecuted this case and sought prison time.
