The Unreliability of Breath Testing
Breath testing is a critical tool used by law enforcement officers to measure a person’s blood alcohol content (BAC) and determine whether they are driving under the influence (DUI). However, these tests, while commonly used, are far from flawless. Many individuals arrested on suspicion of DUI are unaware of the numerous factors that can result in inaccurate breathalyzer readings. Willis Law Firm understands the complexities surrounding breath testing and can provide the expertise needed to challenge potentially flawed results.

This method, although convenient for officers in the field, can be impacted by various technical and physiological factors. As such, individuals facing DUI charges based on breath testing should be aware of these potential flaws, as they may have a significant impact on the outcome of the case.
Common Factors Leading to Inaccurate Breath Test Results
Breathalyzers are designed to measure the amount of alcohol in a person’s breath, which is then used to estimate their BAC. However, this estimation can be influenced by a range of issues. Below are some of the most common factors that may lead to inaccurate breath test results:
- Mouth Alcohol Contamination
One of the most prevalent causes of false readings on a breathalyzer is mouth alcohol contamination. If a person has recently consumed alcohol, used mouthwash containing alcohol, or has residual alcohol in their mouth from a previous drink, it can interfere with the breath test. Alcohol from the mouth can be mistaken for alcohol in the lungs, resulting in a reading that is significantly higher than the person’s actual BAC.
The issue arises when officers do not wait the required amount of time after a person’s last drink or mouthwash use before administering the breath test. For example, breathalyzers typically require a 15-minute observation period to ensure the person does not burp, regurgitate, or eat, all of which can affect the result.

- Improper Calibration of the Device
Breathalyzer devices must be calibrated regularly to ensure accurate readings. Unfortunately, law enforcement agencies often overlook the necessary maintenance and calibration of these machines. Without proper calibration, the machine may fail to provide reliable results. A poorly calibrated device could lead to a reading that falsely indicates a higher BAC than the person’s actual alcohol concentration.
This is a major issue, as the law requires breathalyzers to be calibrated frequently. If you’ve been arrested and suspect that the breathalyzer was not properly calibrated, it’s important to discuss this concern with an experienced attorney from Willis Law Firm.
- Malfunctioning or Faulty Equipment
Another common issue with breath testing is faulty or malfunctioning equipment. Over time, breathalyzer devices may degrade or suffer from technical issues that affect their accuracy. For example, a malfunction in the sensor may cause the machine to produce inaccurate readings. The law mandates that breathalyzers undergo regular maintenance and testing, but in reality, these protocols are sometimes neglected, leading to unreliable results.
Malfunctions in the device could also lead to a false positive or an incorrect BAC reading. Whether due to age, lack of proper maintenance, or improper handling, faulty breathalyzers can result in severe consequences for an individual who may not actually be impaired.
- Environmental Factors Affecting Readings
Breathalyzer machines are sensitive to their environment, and certain external factors can skew the test results. Temperature, humidity, and even atmospheric pressure can affect the sensors within the device. In particular, cold weather can cause condensation inside the device, leading to incorrect readings.

In some cases, breathalyzers may also be impacted by the person’s breathing pattern. If an individual is nervous or hyperventilates, it can alter the way their breath is sampled, leading to an inaccurate reading. It’s essential for officers to account for these environmental factors when using a breathalyzer, but this doesn’t always happen in the real world.
- Medical Conditions that Affect Breathalyzer Accuracy
Certain medical conditions can also interfere with breathalyzer results. Conditions like acid reflux, diabetes, and even some respiratory diseases can cause the body to produce compounds such as acetone. Acetone is a chemical that breathalyzers sometimes mistake for alcohol, leading to a false positive result.
For example, individuals with diabetes may produce higher levels of acetone when their blood sugar is not properly regulated. Similarly, acid reflux or GERD can cause alcohol-like compounds to enter the mouth and be detected by the breathalyzer, even if the individual has not consumed alcohol. These medical factors can significantly affect the outcome of a breath test, potentially leading to a wrongful DUI charge.
