What Can Cause a False Positive on a Breathalyzer?

Discover the common causes of false positives on breathalyzers and understand your rights if wrongly accused of DUI.

Introduction to Breathalyzer Tests

Breathalyzers are commonly used by law enforcement to measure blood alcohol concentration (BAC) in individuals suspected of driving under the influence (DUI). However, these devices are not infallible and can produce false positive results due to various factors.

A false positive reading can have severe consequences, including arrest, fines, and damage to one's reputation. It is essential to understand the potential causes of false positives to navigate the legal system effectively and protect one's rights.

Common Causes of False Positives

Several factors can contribute to false positive breathalyzer readings, including the presence of mouth alcohol, acid reflux, and certain medical conditions. Additionally, the use of mouthwash, breath fresheners, or other substances containing alcohol can also affect the accuracy of the test.

Furthermore, human error, such as improper calibration or maintenance of the device, can also lead to false positive results. It is crucial to identify these potential causes to build a strong defense against DUI charges.

The Impact of Medical Conditions

Certain medical conditions, such as diabetes, gastroesophageal reflux disease (GERD), and dental issues, can increase the risk of false positive breathalyzer readings. For instance, individuals with diabetes may have high levels of acetone in their breath, which can be misinterpreted as ethanol by the breathalyzer.

It is essential to disclose any relevant medical conditions to the authorities and to consult with a qualified attorney to determine the best course of action in such cases.

Challenging False Positive Results

If you have been wrongly accused of DUI due to a false positive breathalyzer reading, it is crucial to challenge the results in court. A skilled attorney can help you navigate the legal process and gather evidence to support your case, including expert testimony and documentation of any relevant medical conditions.

Additionally, it may be possible to obtain a blood test or other chemical testing to confirm or refute the breathalyzer results, providing a more accurate measurement of BAC.

Protecting Your Rights

If you are facing DUI charges due to a false positive breathalyzer reading, it is essential to seek the advice of a qualified attorney who specializes in DUI defense. They can help you understand your rights and options, including the possibility of having the charges dismissed or reduced.

Remember, a false positive breathalyzer reading does not necessarily mean you are guilty of DUI. By taking prompt action and seeking the right legal representation, you can protect your rights and work towards a favorable outcome in your case.
