DWI Laws in Texas

The state of Texas does not treat DWI offenses lightly. Under Texas law, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08% or higher. However, even with a lower BAC, you can still face DWI charges if an officer determines that your mental or physical faculties are impaired by alcohol or drugs.

Underage DWI (referred to as DUI)

Defense Strategies for DWI Charges in Williamson County

A strong DWI defense requires a detailed review of your case to identify weaknesses in the prosecution's argument. Attorney Ryan H. Deck uses proven DWI defense strategies, including:

Challenging BAC Test Results

Breathalyzers and blood tests can produce inaccurate results due to improper calibration or faulty administration. We analyze testing records and challenge the reliability of BAC evidence.

Questioning Field Sobriety Tests

Field Sobriety Tests (FSTs) are subjective and not always reliable. Medical conditions, poor balance, and nervousness can all impact test results.

Illegal Traffic Stops

Police officers must have reasonable suspicion to stop your vehicle. If the stop was unlawful, any evidence collected may be suppressed.

Rising BAC Defense

BAC levels continue to rise after drinking, meaning your BAC may have been lower while driving. We argue that the BAC test results do not reflect your condition at the time of driving.

Medical Conditions and Prescription Medications

Medical conditions like diabetes or GERD can produce false positives in breath tests. We use medical evidence to support alternative explanations for test results.

What to Do If You’re Pulled Over for a DWI

If you are stopped for suspicion of DWI, follow these steps:

Remain Calm & Cooperate

Provide identification and comply with basic requests.

Exercise Your Rights

You do not have to answer questions beyond providing your name and driver’s license.

Decline Field Sobriety Tests

These tests are voluntary and often unreliable.

Accept the Breathalyzer Test

You can refuse the test, but refusal leads to automatic license suspension.
