Common DWI Defenses in San Antonio

  2. Questioning Field Sobriety Tests
    Tests like the walk-and-turn or one-leg stand are subjective and affected by weather, lighting, or physical conditions (e.g., injuries, fatigue). We challenge the officer’s administration and interpretation.
  3. Disputing Blood Test Validity
    Blood tests can be compromised by improper collection, storage, or analysis. We investigate chain-of-custody issues to suppress evidence.
  4. Proving Unlawful Arrest
    If the traffic stop lacked probable cause or your rights were violated (e.g., improper Miranda warnings), we may move to dismiss the case or suppress evidence.
  5. Case Study: Reducing a 9th DWI
    In a recent case, Brad Thornton represented a client facing a 9th DWI, a habitual offender charge with a potential life sentence. By challenging the prosecution’s evidence and negotiating strategically, Brad secured a plea to a misdemeanor, avoiding prison time. .

These strategies, combined with our deep knowledge of Texas DWI laws, position us to achieve dismissals, reduced charges, or acquittals. to discuss your defense.

Frequently Asked Questions About DWI Defense in San Antonio

Expert Answers from Brad Thornton, Board-Certified DWI Attorney

After a DWI arrest in San Antonio, you will typically be taken before a Bexar County Magistrate, often within hours of your arrest. The magistrate sets bond, explains the charges, and issues important paperwork—especially regarding your driver’s license. One of the most critical steps is acting quickly to protect your license. You generally have 15 days from the date of arrest to request an Administrative License Revocation (ALR) hearing. Speaking with an experienced San Antonio DWI lawyer immediately can help ensure deadlines are met and evidence is preserved.
The length of a driver’s license suspension depends on several factors, but the most important issue is the 15-day ALR deadline. If you fail or refuse a breath or blood test and do not request an ALR hearing within 15 days, your license suspension will automatically begin. A failed test can lead to a suspension of up to 90 days or more, while a refusal can result in a 180-day suspension or longer. Requesting an ALR hearing can delay the suspension and create an opportunity to challenge the arrest.
In Texas, refusing a breath or blood test triggers immediate legal consequences. In San Antonio and throughout Bexar County, refusal almost always leads to a license suspension and, in many cases, a forced blood draw. Texas operates under aggressive “No Refusal” enforcement, meaning officers can quickly obtain a warrant for your blood. Refusal is not a free pass—it often becomes a key issue in both the criminal case and the ALR license case.
Yes, a DWI charge can be dismissed, but it depends on the facts. Dismissals often stem from illegal traffic stops, unconstitutional searches, unreliable field sobriety tests, or problems with breath or blood evidence. In Bexar County, an experienced DWI attorney can also challenge whether officers followed proper procedures during the arrest and investigation. Every case is different, but strong legal defenses can significantly improve the outcome.
In Bexar County, “No Refusal” is effectively a 24/7, 365-day policy. This means that if you refuse a breath or blood test, San Antonio police can immediately contact an on-call judge to obtain a search warrant for your blood. Judges are routinely available, even late at night and on weekends. Because these warrants must meet strict legal and technical requirements, having a board-certified DWI attorney who understands how to challenge them is critical.
Most DWI cases in San Antonio are handled at the Bexar County Courthouse, located at 300 Dolorosa, San Antonio, TX 78205. DWI cases are commonly assigned to courts such as County Court at Law No. 7 or County Court at Law No. 13, though assignments can vary. Knowing the local courts, judges, and procedures can make a meaningful difference in how a case is handled.
Yes. If your driver’s license is suspended after a DWI arrest, you may be eligible for an Occupational Driver’s License (ODL). An ODL allows limited driving for essential purposes such as work, school, or household duties. In San Antonio, this requires filing a petition with a Bexar County court and often providing proof of insurance. A DWI lawyer can help prepare and file the petition quickly so you can stay on the road legally.
Failing a blood test does not automatically mean a conviction. Blood evidence must follow strict rules, including proper chain of custody, correct use of preservatives, and accurate laboratory analysis. As a former prosecutor, Brad Thornton knows exactly where these cases break down and aggressively examines lab procedures for errors that can lead to reduced charges or dismissal.
Missing the 15-day ALR deadline is serious, but it is not the end of the road. Even if your license suspension has started, you may still be able to drive legally by obtaining an Occupational Driver’s License. A San Antonio DWI attorney can evaluate your situation and guide you through the fastest path to restoring limited driving privileges.
Yes. In Texas, a DWI with a child passenger under the age of 15 is charged as a State Jail Felony, even if it is your first DWI offense. A conviction can result in jail time, fines, and long-term consequences. These cases are prosecuted aggressively in Bexar County, making immediate legal representation especially important.
