Texas enforces a zero-tolerance alcohol policy for drivers under 21. Under the Texas Traffic Code, any detectable alcohol at or above a BAC of 0.02% can support a DUI charge for a minor. If the minor’s BAC reaches 0.08% or above, the case may be prosecuted as a standard DWI under the Penal Code rather than the Traffic Code, carrying criminal penalties rather than just license consequences. A conviction at either level can affect college applications, scholarship eligibility, and professional licensing for years. From arrest, the 15-day ALR window begins. Miss it and the license is automatically suspended.
David Smith is Board Certified in Criminal Law by the Texas Board of Legal Specialization and a former Brazoria County prosecutor. Underage DWI cases require a defense that understands both the juvenile court system and the adult criminal court system, because depending on the facts, age, and BAC level, the case may be handled in either one. He also understands the long-term record consequences that matter most to a young person and their family, and he build a defense strategy around protecting the future, not just resolving the current charge.

The zero-tolerance standard changes the legal landscape entirely. At 0.02%, a margin of error in the breath testing instrument or a slight variance in the timing of the test relative to alcohol consumption can be the difference between a charge and no charge. The stakes are also different from an adult case. A conviction or even a deferred adjudication can show up on background checks that affect college admissions, financial aid, military enlistment, and professional licensing. Board Certification in Criminal Law by the Texas Board of Legal Specialization is a credential that reflects expertise across the full range of consequences these cases carry.
Our defense in underage DWI cases addresses the charge itself, the record consequences, and the long-term options for record relief. We focus on:
As part of a DWI sentence or plea agreement in Texas, courts frequently order the installation of an Ignition Interlock Device (IID) , a breath-testing instrument connected to your vehicle’s ignition that requires a clean breath sample before the engine will start.
