Understanding Breathalyzer Tests in DUI Cases

Breathalyzer tests are commonly used by law enforcement to measure the amount of alcohol in a person’s breath, which is then used to estimate blood alcohol concentration. While these devices are valuable tools, they are not infallible. A variety of factors can influence the results, including medical conditions that might cause inaccurate readings. If you believe the results of your Breathalyzer test are misleading, it is critical to explore these possibilities and build a strong defense for your case.

Medical Conditions That Can Impact Breathalyzer Results

Certain medical conditions have been shown to affect Breathalyzer readings, sometimes leading to false positives or elevated results. For example, people with acid reflux or gastroesophageal reflux disease may have alcohol vapors from their stomach rise into their esophagus and mouth, which can interfere with the device’s reading. This situation is often not representative of the individual’s actual blood alcohol concentration. Diabetes is another medical condition that can lead to inaccurate results. Individuals with diabetes, especially those who experience low blood sugar, may produce acetone in their breath. Breathalyzer devices can mistakenly identify acetone as alcohol, resulting in a higher reading than is accurate. This can lead to unjust accusations of driving under the influence. People with chronic obstructive pulmonary disease, asthma, or other respiratory issues may also have difficulty producing a proper breath sample for the test. In some cases, their inability to provide a strong and consistent breath sample can result in unreliable results or even test failures. Understanding how these conditions interact with Breathalyzer devices is an important step in challenging questionable results.

Improper Calibration and External Factors

Even without medical conditions, Breathalyzer results can sometimes be unreliable. These devices require regular maintenance and calibration to ensure accuracy. If the device used during your test was not properly maintained or calibrated, its reading could be flawed. External factors such as mouthwash, breath fresheners, or even certain diets can also impact results. These details may seem minor but can play a significant role in your defense.

Building a Defense for Your DUI Case

Challenging the results of a Breathalyzer test begins with a thorough investigation of the circumstances surrounding your arrest and test. Analyzing the maintenance records of the device, the training and actions of the officer who administered the test, and any potential medical conditions you have is key to identifying weaknesses in the prosecution’s case. Your defense may also involve obtaining testimony from medical professionals or presenting evidence that casts doubt on the validity of the test results.

The Importance of Medical Evidence in DUI Defenses

Medical records and testimony can play a critical role in challenging the results of a Breathalyzer test. If you have a medical condition that may have impacted the reading, providing documentation and having a medical professional explain the condition’s effects can significantly strengthen your case. For example, showing evidence of a diabetes diagnosis or an existing condition like acid reflux can demonstrate that your test results may not accurately reflect your level of impairment. This approach can shift the focus from the Breathalyzer results to the broader circumstances of your case, creating reasonable doubt.

The Role of Field Sobriety Tests and Officer Conduct

In many DUI cases, the results of a Breathalyzer test are used in combination with field sobriety tests to establish impairment. However, these tests are also subject to error and interpretation. Physical limitations, nervousness, or unfamiliarity with the procedures can lead to poor performance on these tests, regardless of alcohol consumption. Furthermore, the officer’s conduct during your arrest is critical to examine. If an officer failed to administer the test correctly, disregarded proper protocol, or ignored your medical conditions, this could provide grounds to challenge the results and procedures in court.

How Stress and Anxiety Can Impact Results

Being pulled over and subjected to a Breathalyzer test can be an extremely stressful experience. For some individuals, this stress can trigger physical reactions that influence the test results. For example, hyperventilation or shallow breathing caused by anxiety may affect the breath sample provided. While this is not directly related to medical conditions, it highlights another potential flaw in the reliability of these tests. By addressing the circumstances leading up to the test and the state of mind you were in, a defense strategy can cast further doubt on the prosecution’s claims.

Why Prompt Action Matters in DUI Cases

Time is of the essence when defending against DUI charges in South Carolina. Evidence can become harder to obtain as time passes, and deadlines for certain legal filings may approach quickly.
