DWI Testing & Refusals Attorney In Dallas, Texas
Protecting Your Rights During DWI Investigations
When law enforcement suspects a driver of operating a vehicle while intoxicated, they often rely on field sobriety tests, breath tests, and blood tests to gather evidence. While these tests can play an important role in a DWI investigation, they are not always accurate or administered correctly. Improper procedures, faulty equipment, medical conditions, and human error can all affect the reliability of test results. If you have been arrested for DWI, understanding your rights regarding chemical testing and refusals is essential.
At The Law Offices Of Robert S. Gregg, we understand that DWI cases often involve complex scientific and legal issues. A failed breath or blood test does not automatically mean you will be convicted, and refusing a test does not automatically mean you are guilty. Attorney Robert S. Gregg carefully examines every aspect of the testing process to determine whether law enforcement followed proper procedures and whether the evidence can be challenged.
Our firm represents individuals throughout Dallas, Texas, who are facing DWI charges involving breath tests, blood tests, field sobriety testing, or allegations of refusing chemical testing. We are committed to protecting your rights and pursuing the strongest possible defense.

DWI Testing and Refusal Laws in Texas
Texas operates under an implied consent law, meaning that by driving on Texas roads, motorists are generally considered to have consented to chemical testing under certain circumstances following a lawful DWI arrest. Drivers may choose to refuse a breath or blood test, but doing so can result in administrative penalties, including a driver's license suspension through the Administrative License Revocation (ALR) process.
Breath and blood test results are frequently relied upon by prosecutors, but these tests are not infallible. Breath testing devices require proper calibration, maintenance, and operation, while blood samples must be collected, stored, transported, and analyzed according to strict legal and scientific procedures. Errors at any stage of the testing process may affect the reliability or admissibility of the evidence.
Field sobriety tests are also subject to challenge. Factors such as uneven pavement, poor weather conditions, fatigue, medical conditions, age, physical limitations, or nervousness may affect a person's performance. Likewise, officers must follow standardized procedures when administering these tests, and any deviations may become important issues in your defense.
At The Law Offices Of Robert S. Gregg, we carefully review police reports, body camera footage, dash camera recordings, laboratory records, maintenance logs, and all available evidence. Whenever the facts support it, we aggressively pursue the suppression, reduction, or dismissal of evidence and charges while protecting our clients' constitutional rights.
Building a Strong Defense Against DWI Evidence
The outcome of a DWI case often depends on the quality and reliability of the evidence presented by the prosecution. Challenging chemical testing procedures, questioning the legality of the traffic stop, examining whether probable cause existed for the arrest, and identifying violations of your constitutional rights can all play an important role in building an effective defense.
Attorney Robert S. Gregg takes the time to thoroughly investigate every case and explain your legal options in clear, straightforward terms. We understand that every DWI case is different, which is why we develop personalized defense strategies based on the unique facts surrounding your arrest.
