DWI Defense

San Antonio DWI Defense Lawyer

 When a blood test or breathalyzer comes back with a reading of the blood-alcohol content (BAC) level being 0.08% or higher, that puts them over in the legal limit to operate a motor vehicle in the state of Texas. The result is likely to be a charge for driving while intoxicated (DWI). What happens next is critical for the person being charged. They may be tempted to plead guilty, thinking the evidence is stacked against them. But before doing that, call our San Antonio DWI lawyer. There are a lot more ways than many people realize to challenge a DWI charge. And at The Law Offices of George A. Scharmen, we have plenty of experience and success at doing just that.

Challenging a DWI in Texas

The challenges to a DWI focus broadly on two areas—the legitimacy of administering the BAC level test to begin with, and the accuracy of the reading the test produces. 

All of the following are issues that our San Antonio DWI attorney can investigate:

  • Did the police officer have reasonable suspicion to pull the car over? A police officer can’t randomly pull drivers over (unless it’s at a designated sobriety checkpoint). They need a reason. Leaving a drinking establishment at a late hour is a possible reason, as is any traffic violation, however minor. But there has to be something that a reasonable person would consider valid for pulling a driver over.  
  • Did the police officer have probable cause to administer the BAC level test? Drivers are strongly advised to be quiet when being asked questions at the stop. Even the casual admission to having any alcohol at all is enough to qualify for probable cause. So is having alcohol on one’s breath or slurring one’s words. But again, the police officer must have a credible reason for thinking a person might be legally intoxicated.  
  • Is there video footage of the stop and any roadside tests, like walking in a straight line? The answer better be yes, as officers should have their dashboard camera running during the stop. Our San Antonio DWI lawyer can review the video to see if roadside tests were conducted fairly, especially if these tests are used to establish probable cause for subsequent testing of blood or breath.  
  • Is the breathalyzer equipment being maintained properly? There are strict rules that police stations must following regarding the breathalyzer equipment. They must be maintained and recalibrated according to specific protocols. Officers need to have completed a training session in how to use them. Any deficiency in following protocol can be used as a basis to challenge the results.  
  • What was the driver eating prior to the stop? Did you know that eating bread or sugary foods can cause BAC levels to give off deceptively high readings. Maybe someone is driving home after a wedding where they had cake along with a drink or two. Or they were at Happy Hour and had some appetizers with bread in them over a drink with colleagues. They aren’t intoxicated. But the sugar or bread involved might make it appear so. An experienced attorney will know this.  
  • Was the driver taking any medication? There are common forms of medicine that can cause BAC levels to spike. Cough syrup is one. Even mouthwash could be the culprit. This is another way where he person who has otherwise drank responsibly, and within the legal limit, can be unfairly charged with a DWI. 
  • Was the blood test done properly? A blood sample has its own set of protocols that must be observed. These protocols are called chain of custody, and it means the sample must be accounted for every step of the way. From the time the blood is drawn, to its storage, to its testing, to its return to storage. Failure to maintain chain of custody can render the test inadmissible in court. Failure to store the blood properly can cause it to give an inaccurate reading.

Commonly Asked Questions

What Maintenance Is Required for Breathalyzer Equipment in San Antonio?

Breathalyzer equipment in San Antonio must be maintained and recalibrated according to strict protocols. Officers are also required to complete training on how to properly use the equipment. If these protocols are not followed, the results of a breathalyzer test can be challenged. Our San Antonio DWI defense attorney can investigate whether the equipment was properly maintained and if any deficiencies could affect the validity of your test results.

How Can Food & Medication Affect BAC Readings in a DWI Case?

Certain foods and medications can falsely elevate BAC readings in a DWI case. For example, consuming bread or sugary foods before driving can lead to deceptively high BAC levels. Medications like cough syrup or even mouthwash  can also affect the results. Our team can consider these factors when building a defense, potentially challenging the accuracy of BAC test results.
