Austin Blood & Breath Test DWI Attorney 

When a person is stopped by law enforcement under suspicion of DWI, they may be asked to submit to a blood or breath test. A breath test is performed by use of a breathalyzer machine and with this method of testing, an individual will blow into a device that will measure their breath alcohol concentration. This is said to be almost identical to BAC (blood alcohol content) that can be determined by a simple blood test at the police or sheriff's station. 

Failing a blood or breath test does not automatically mean that you are guilty of DWI (driving while intoxicated) or DUI (driving under the influence). There are many potential problems that can affect the outcome of these tests which can lead to a false arrest. These problems can include, but are not limited to the following:

Blood Tests Issues

  • Improper Training
  • Improper Administration
  • Improper Reading
  • Contamination
  • Improper Storage

Breath Tests Issues 

  • Improper Administration
  • Radio Frequency/Electrical Interference
  • Improper Maintenance
  • Improper Calibration
  • Existing Medical Conditions

What Happens If You Refuse a Blood or Breath Test?

If you are suspected and stopped for DWI or DUI, then you have the legal right to refuse to submit to a blood or breath test. However, if there is a minor in the vehicle or if a DWI accident occurs, then law enforcement is required to take a breath or blood sample, even without your permission. When a person refuses either test, then they may have their driver's license suspended according to the Texas Implied Consent Law.
