Why Texas Drivers Can Face DWI Charges Even Without a BAC Over 0.08
Most people assume that getting a DWI in Texas means blowing over the legal limit on a breathalyzer. It seems straightforward that no failed breath test means no DWI. But that's wrong. In reality, you can be arrested, charged, and even convicted of DWI in Texas without ever failing a breath test. In some cases, you might not even take one at all. Should you find yourself in this situation, it's important to understand how Texas law operates and what steps to take to protect your rights.
What does Texas law actually say about DWI?
Under Texas Penal Code §49.04, you can be charged with DWI if you are:
- Driving a motor vehicle in a public place
- You don’t have the normal use of your mental or physical faculties because of alcohol, drugs, or both
You’ll also be charged with DWI if your blood alcohol concentration (BAC) is 0.08% or higher. That’s the number everyone hears about. But you don’t need to hit 0.08 to be considered legally intoxicated. If the officer believes you’re impaired (even slightly), you can still face a DWI charge.
How can you get a DWI without failing the breath test?
There are a few ways this plays out. Let's say you get pulled over, maybe for swerving or rolling through a stop sign. The officer approaches your car and begins making observations.
They might notice:
- The smell of alcohol
- Slurred speech
- Red or watery eyes
- Trouble finding your license or registration
- Slow or clumsy movements
- Confusion or trouble answering questions
If they see enough signs of impairment, they can ask you to step out and take field sobriety tests. These are the tests where you’re asked to walk a straight line, follow a pen with your eyes, or stand on one leg. If you don’t perform those well (even if you’re under the legal limit), they can arrest you and charge you with DWI based on observable signs of intoxication.
What if you refuse the breath test altogether?
In Texas, like in many states, there's something called implied consent. That means by driving on Texas roads, you've legally agreed to take a chemical test (e.g., breath or blood test) if an officer suspects you're driving under the influence. You can refuse a breath test, but there are consequences. These include:
- Automatic license suspension (typically 180 days for a first refusal)
- The officer may get a warrant for a blood draw anyway
- Your refusal can be used against you in court
Importantly, refusing the test won’t stop you from getting arrested. The officer just needs enough reason to believe you’re impaired, and they can still charge you without a breathalyzer result.
What if you pass the breath test but still seem impaired?
Even if you blow under 0.08%, you’re not necessarily off the hook. That’s because alcohol affects everyone differently. Someone could be legally intoxicated, which means their mental or physical abilities are compromised, even with a BAC of 0.05 or 0.06.
There's also the drug factor. If the officer believes you’re under the influence of marijuana, prescription drugs, or other substances, a breathalyzer won’t catch that. In those cases, they might bring in a drug recognition expert or request a blood test instead. So yes, you can pass a breath test and still be arrested for DWI, especially if drugs, medications, or alcohol tolerance are involved.
What about legal medications? Can they lead to a DWI?
Texas DWI laws don’t just apply to illegal drugs or heavy drinking. If you’re taking a prescription or over-the-counter medication that makes you drowsy, dizzy, or otherwise impairs your ability to drive safely, you can still be charged. For example:
- Painkillers (even prescribed ones)
- Sleep aids
- Anxiety medication
- Certain antihistamines
Even if you took the medicine as prescribed, you’re still responsible for how it affects your driving. The law doesn’t make exceptions for “legal” drugs if they leave you impaired behind the wheel.
What kind of evidence do police use in DWI cases without a breath test?
When there's no breath test or you pass it, the prosecution leans heavily on other forms of evidence. These might include:
- Police dashcam or bodycam footage
- Field sobriety test performance
- Statements you made (like “I only had a couple drinks”)
- Witness accounts of your driving
- The officer’s own testimony
- Blood test results, if one was taken
In court, all of this can be used to convince a jury that you were intoxicated, even if there’s no breathalyzer result on record.
How can a DWI attorney help in this situation?
If you’ve been charged with DWI and didn’t fail a breath test (or never took one), you might assume the case is weak. But don’t count on the system letting you off easy. Prosecutors often double down on officer testimony and field sobriety tests. That’s where having a skilled DWI defense lawyer helps. An attorney can:
- Challenge the legality of the traffic stop
- Question how field sobriety tests were administered
- Dispute the officer’s interpretation of your behavior
- Highlight alternative explanations (fatigue, health issues, anxiety)
- Suppress evidence gathered improperly
