Understanding Breathalyzer Tests in Texas
A breathalyzer is a device used by law enforcement to estimate blood alcohol concentration (BAC) from a breath sample. In Texas, these devices are commonly used during traffic stops when an officer suspects intoxication.
However, breathalyzer machines do not directly measure alcohol in the bloodstream. Instead, they estimate BAC based on breath alcohol levels, which can introduce potential inaccuracies. Because of this, the results may be challenged under certain circumstances in Travis County courts.
Are Breathalyzer Results Always Accurate?
Breathalyzer devices are generally considered reliable when properly maintained and administered. However, several factors can affect their accuracy, including:
- Improper calibration or maintenance
- Operator error during testing
- Environmental conditions
- Medical conditions such as acid reflux or diabetes
- Residual alcohol in the mouth
Because these factors can influence the results, a criminal defense lawyer may examine whether the test was conducted in compliance with Texas regulations.
Legal Grounds to Challenge a Breathalyzer Result
In Travis County, a breathalyzer result may be challenged on several legal grounds. Each case depends on its specific facts, but common arguments include:
Improper Traffic Stop
If the initial traffic stop was not supported by reasonable suspicion, any evidence obtained afterward—including breathalyzer results – may be subject to suppression. Courts in Texas carefully review whether law enforcement had a valid reason to stop a driver.
Failure to Follow Proper Procedures
Texas law requires officers to follow strict procedures when administering breath tests. If the officer did not observe the required waiting period or failed to follow protocol, the results may be questioned.
Machine Maintenance and Calibration Issues
Breathalyzer machines must be regularly calibrated and maintained. Records showing improper maintenance or irregular calibration schedules can raise doubts about the reliability of the results.
Operator Certification
The officer administering the breath test must be properly trained and certified. If certification requirements were not met, this may impact the admissibility of the test results.
Medical or Physiological Factors
Certain health conditions may affect breath test readings. For example, individuals with GERD or diabetes may produce breath samples that register higher alcohol levels than are actually present in the bloodstream.
How Travis County Courts Evaluate Breathalyzer Evidence
Courts in Travis County do not automatically accept breathalyzer results as unquestionable proof. Instead, judges and juries may consider:
- Whether the test was properly administered
- The credibility of the officer
- Maintenance and calibration records
- Expert testimony regarding the device’s reliability
An experienced Austin DWI lawyer may work with forensic experts to analyze the evidence and identify weaknesses in the prosecution’s case.
The Role of an Austin Criminal Defense Lawyer
Challenging a breathalyzer result often requires a detailed understanding of both Texas law and scientific principles. Criminal defense lawyers may:
- Review police reports and dashcam footage
- Request maintenance and calibration logs
- Examine the officer’s training and certification
- Consult with expert witnesses
- File motions to suppress unreliable evidence

What Happens If the Breathalyzer Result Is Excluded?
If a court determines that a breathalyzer result is unreliable or was obtained improperly, it may be excluded from evidence. This does not automatically mean the case will be dismissed, but it can significantly impact the prosecution’s ability to prove intoxication.
In some situations, the prosecution may rely on other evidence, such as:
- Field sobriety test results
- Officer observations
- Video recordings
Even so, the absence of breathalyzer evidence can strengthen a defense strategy depending on the circumstances.
Texas Implied Consent Law
Texas has an implied consent law, which means that drivers who are lawfully arrested for DWI may be required to submit to chemical testing. Refusing a breath test can result in administrative penalties, such as license suspension.
However, even if you took the test, you still have the right to challenge the results in court. A criminal defense lawyer can help you understand how implied consent laws may affect your case.
Why Early Legal Representation Matters
The sooner you consult with an Austin DWI lawyer, the more opportunities there may be to preserve evidence and build a defense. Time-sensitive factors include:
- Requesting an Administrative License Revocation (ALR) hearing
- Securing maintenance and calibration records
- Identifying potential witnesses
