Due to the implied consent law in Texas, drivers can face serious criminal consequences if they refuse to take a breath or blood test when pulled over for suspected DWI. If you submitted to a breath test or blood test and were charged with DWI as a result, we can carefully examine the evidence against you. The Intoxilyzer 5000 is the breath test device used in Texas to measure a driver’s blood alcohol concentration (BAC). When a person blows into the machine, the alcohol in their breath will be measured by the breathalyzer. A driver can request a blood test instead, which will be used to determine the level of alcohol in the driver’s blood. A blood test can also be used to identify the presence of drugs. The following may cause inaccurate blood and breath test results:

• Breathalyzer was incorrectly calibrated
• Breathalyzer was not calibrated recently
• Police officer improperly administered the test
• Defendant has a dental/medical condition that skews breath test results
• Poorly trained lab technicians made a mistake in analyzing blood
• Blood evidence was mishandled
• Chain of custody was broken in handling blood evidence
