DWI Defense Lawyer in San Marcos

Fighting Driving While Intoxicated Charges in Texas

Being convicted of, or even merely charged with, a DWI can severely impact your life. Immediately after your arrest, you face a driver's license suspension, making it difficult to take care of daily tasks. If the court finds you guilty, you could lose your driving privileges, face fines, or risk jail time. Because the consequences of a DWI charge are so severe, you need an experienced and knowledgeable DWI defense lawyer in San Marcos on your side. Solid legal defense can increase your chances of minimizing or avoiding harsh penalties.

These cases often involve technical details and scientific evidence. Prosecutors use field sobriety tests and chemical test results to try to prove guilt. At Smith & Vinson Law Firm, our team knows that scientific measurements have limitations, and many factors may affect the results besides drugs or alcohol. Our San Marcos DWI lawyers examine every detail of your situation to determine what defenses to raise and how to present your case in the strongest way possible.

Your Defense Against DWI Charges Strong Representation When It Matters Most
A DWI charge can have serious consequences, but you don’t have to face it alone. Our experienced team will fight to protect your rights, minimize penalties, and help you take control of your future.

How Serious Is a DWI in Texas?

A DWI charge in Texas carries serious consequences. Even before your case concludes, you may face penalties that affect your family, education, and job. A conviction creates a permanent criminal record, which can impact job opportunities and future plans. Most people don't realize a DWI conviction can also cause steep insurance premium increases and create a long-term financial burden.

Understanding Texas law matters, because in addition to standard penalties, you could also face community service, alcohol education programs, or court-ordered ignition interlock devices in your vehicle. These penalties limit both personal freedom and professional options. Working with a DWI attorney in San Marcos gives you support in creating a strategy that considers every consequence you might face.

Texas Penal Code § 49.04 defines DWI as operating a vehicle in a public place while intoxicated by alcohol and/or controlled substances. Intoxication means:

  • The driver's normal mental or physical faculties were impaired by alcohol and/or drugs, making safe driving impossible; or
  • The driver had a blood or breath alcohol concentration of 0.08 or higher.

Generally, first and second DWI violations are misdemeanors, but penalties will depend on the facts of the case.

FAQs About DWI in San Marcos

  • If you find yourself being pulled over under suspicion of DWI in San Marcos, it is crucial to remain calm and collected. First, slow down and pull over to a safe area as soon as possible. Always have your driver’s license, registration, and proof of insurance ready. Keep your hands visible on the steering wheel and be polite to the officer. While you are legally required to provide the requested documents, you are not obligated to answer questions that may incriminate you, such as whether you have been drinking. Politely inform the officer that you choose to decline answering questions. Consider telling the officer that you would like to consult with an attorney as soon as possible. If you are arrested, remember that anything you say may be used against you. Ask to speak with a DWI lawyer immediately to discuss your legal options.
  • Hiring a skilled DWI attorney is one of the most effective steps you can take if charged with a DWI in San Marcos. A lawyer will evaluate all aspects of your arrest, including the legality of the traffic stop, the accuracy of field sobriety and chemical tests, and any procedural discrepancies. By challenging the evidence, your lawyer might find grounds for dismissal or reduction of charges. Additionally, San Marcos DWI lawyers have the negotiation skills to arrange plea deals or alternative sentences, such as participating in alcohol education programs, which can mitigate the consequences of a conviction. An attorney will also represent you at DMV hearings regarding your driver's license suspension, trying to prevent or shorten the suspension period. With in-depth knowledge of Texas DWI law and courtroom procedures, your attorney can craft a comprehensive defense strategy aimed at achieving the best possible outcome.
  • A DWI conviction extends beyond immediate penalties such as fines or jail time. It may result in significant long-term consequences that can impact various aspects of your life. A criminal record from a DWI conviction can affect your employment opportunities, as many employers conduct background checks and may be hesitant to hire someone with a conviction. It can also impact current employment if your job involves driving. Furthermore, your insurance premiums are likely to increase significantly after a DWI, resulting in long-term financial strain. A DWI conviction can also affect your personal life, potentially leading to restricted travel opportunities, both nationally and internationally, depending on certain countries' entry policies regarding criminal records. Given these potential repercussions, it is crucial to fight a DWI charge with a solid legal defense to minimize its impact on your future.
  • In Texas, DWI (Driving While Intoxicated) and DUI (Driving Under the Influence) are distinct offenses that differ mainly by the age of the offender and the level of intoxication. DWI is a charge applied to adults (21 or older) who operate a vehicle while impaired by alcohol or drugs, with a BAC of 0.08% or higher. On the other hand, DUI is specific to minors (under 21) who drive with any detectable level of alcohol in their system, not requiring a BAC of 0.08% or more. The consequences also vary significantly; while a DWI involves potential penalties like hefty fines, jail time, and license suspension, a DUI for minors often results in fines, alcohol education programs, and community service. Understanding these differences is essential for properly addressing either charge in court.
  • Chemical test results, such as those from breath, blood, or urine tests, play a crucial role in DWI cases but are not infallible. An experienced DWI lawyer can challenge these results on several fronts. One common issue involves questioning the accuracy and maintenance of the testing device. If the device was not properly maintained or calibrated according to state protocols, it could yield incorrect results. Additionally, the timing of the test can be a factor; if taken too long after driving, it may not accurately reflect the driver's condition at the time of the stop. Procedural errors, such as an officer failing to observe the subject for a required observation period before testing, can also be grounds for contesting the results. Your defense attorney will examine these and other factors to dispute the reliability of chemical test outcomes and advocate for a favorable resolution in your DWI case.
