Breath & Blood Tests in Austin, TX
Representation From DWI Test Attorneys in Travis County
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.
Texas Breathalyzer Tests
The breath test is a common method used by law enforcement to measure a driver's blood alcohol concentration (BAC) to determine if they are intoxicated. In Texas, this test is typically administered using a machine called the Intoxilyzer 9000. Although most other states have upgraded to using more accurate equipment, Texas remains behind the curve.
To secure a DWI conviction, the State must prove beyond a reasonable doubt that you were intoxicated while driving. Even if your breath test result was above 0.08, don't lose hope. The breath test is just one piece of evidence, and proving intoxication can be challenging. If your breath test results are 0.08 or higher, you’ll need an Austin breath test attorney to demonstrate the unreliability of the machine. At Smith & Vinson Law Firm, our Austin DWI attorneys can review your case to determine if there was reasonable suspicion or probable cause for your traffic stop. We can also challenge the breath test procedures used by the arresting officer, ensuring that every aspect of your case is thoroughly examined.
Texas BAC Blood Tests
The blood test is another way law enforcement measures the amount of alcohol in a person's bloodstream. If an officer suspects you are driving while intoxicated, they may request a blood test, especially if a breath test is not feasible or if you refuse it. A qualified medical professional will draw a blood sample, which is then sent to a laboratory for analysis.
Texas law includes implied consent for blood tests, meaning that refusing a blood test can lead to automatic license suspension and other penalties. While you have the constitutional right to refuse a blood test, doing so can result in your license being suspended, and your refusal can be used as evidence against you in court. Even during Texas’ “no refusal weekends,” you can refuse a blood test, but the police will then need to obtain a warrant to draw your blood.
If you do undergo a blood test, it's important to know that the accuracy of the results can be challenged in court by scrutinizing various factors, including, but not limited to, the following:
- Method of blood sample collection
- Handling and storage of the sample
- Chain of custody
- Qualifications of the person who drew the blood
- Lab procedures
If you are facing a DWI charge based on a BAC blood test, consult with an experienced attorney who can evaluate the circumstances of your arrest and the administration of the test to build an effective defense.
