Knowing your rights and understanding how to challenge breathalyzer test results will make a significant difference in your case. In this blog, we will provide valuable information on challenging breathalyzer tests, offering a lifeline for those in this difficult situation.

How Breathalyzer Tests Work

Breathalyzers measure the alcohol content in a person’s breath, which is used to estimate blood alcohol concentration (BAC). The suspect blows into the device, and the result is used as evidence of impairment. The underlying principle is that alcohol in the bloodstream is expelled through the lungs, and the breathalyzer detects this alcohol.

Factors Affecting Breathalyzer Results and Potential Errors

Several factors can influence the accuracy of breathalyzer results in Galveston and League City, Texas, including:

• Mouth Alcohol: Residual alcohol in the mouth from recent drinking, mouthwash, or other sources can mess up results.
• Recent Surgery: Medical conditions or surgeries affecting the digestive system can impact breathalyzer readings.
• External Factors: Calibration errors, device malfunctions, and environmental conditions can lead to inaccurate results.

Potential errors in breathalyzer testing include:

• Equipment Malfunction: Breathalyzers require regular maintenance and calibration. Failure to properly maintain the device can lead to incorrect readings.
• Operator Error: Improper use of the breathalyzer by the administering officer can result in false positives.
• Environmental Interference: Radio frequencies, cell phone signals, and other electronic devices can interfere with breathalyzer accuracy.

Challenging Breathalyzer Results

Challenging breathalyzer results can be complex, but a skilled Houston DWI lawyer can help. There are several grounds for challenging breathalyzer results. One is equipment malfunction, which involves demonstrating that the breathalyzer device was not functioning correctly due to a lack of maintenance or calibration. Another ground is operator error, where you must prove that the officer administering the test did not follow proper procedures. Additionally, chain of custody issues can be highlighted, showing that the breathalyzer test results were not properly documented or handled, thus casting doubt on their accuracy.

The Role of Expert Witnesses

Expert witnesses, such as forensic toxicologists, can provide testimony on the potential inaccuracies of breathalyzer tests. Their expertise can highlight flaws in the testing process and support challenges to the results.

Legal Defenses

A strong defense may include arguments such as questioning the legitimacy of the traffic stop, disputing the accuracy and administration of the breathalyzer test, and highlighting procedural errors or rights violations during the arrest process.

Gathering Evidence

Detailed documentation of the arrest process and the administration of the breathalyzer test can highlight inconsistencies or errors that may support your defense. Other evidence should be collected:

• Police Reports: Obtain the officer’s report detailing the reason for the traffic stop, the administration of the breathalyzer test, and the results.
• Arrest Records: Review the records for any discrepancies or procedural errors.
• Witness Statements: Collect statements from witnesses who can testify about the circumstances of the arrest and the administration of the test.

Ensure that all evidence is preserved and accessible. This includes maintaining copies of all documents, photographs, and any electronic records related to the case.

The Legal Process

Navigating the legal system in Houston, Texas, can be complex. It’s essential to understand the process and the steps involved in challenging a breathalyzer test result.

Possible outcomes can range from dismissal of charges to a reduction in penalties. The specific outcome will depend on the strength of the evidence and the effectiveness of the legal defense.

Be aware of the timelines and deadlines associated with filing motions and presenting evidence. Missing a deadline can significantly impact the outcome of your case.
