It’s important to realize that the state of Texas distinguishes between DWI (Driving While Intoxicated) and DUI (Driving Under the Influence). DWIs are usually charged to individuals who are legally intoxicated (.08 BAC) or who have lost control of their mental and/or physical capacity to responsibly operate a vehicle.

However, a DUI is typically issued to persons under 21 years of age who are found driving with any detectable amount of alcohol in their system. If these are you or your family’s circumstances, contact a DUI attorney immediately to review your case.

Our Firm Can Fight for You

When we begin building your defense, we combine the facts of your case with our legal knowledge, experience, and research of transportation codes, case law and legal precedents. There are a number of reasons your case may have been handled improperly or was unjustified from the start, including:

  • The arresting officer did not truly have probable cause to pull you over or the reason for pulling you over was flimsy, at best.
  • Reports from third-party witnesses do not corroborate the police report.
  • An unverified anonymous drunk-driving tip was the reason for your arrest.
  • The field sobriety test was not administered properly and/or the arresting officer was not properly qualified to administer field sobriety tests.
  • A test other than the Standardized Field Sobriety Test was used, or the field sobriety test results cannot be trusted due to medical conditions, environmental conditions such as weather, or the surface on which it was administered.
  • The arresting officer did not properly provide your Miranda warning (did not read your Miranda rights).
  • Blood test results cannot be trusted due to lack of qualifications by the technician or unsanitary conditions.
  • Legal protocols were not followed properly, such as the 15-minute observation period.
