Understanding Breathalyzer Tests
Breathalyzer tests are commonly used by law enforcement officers to measure a person’s blood alcohol content (BAC) by analyzing a breath sample. These tests are designed to estimate the amount of alcohol in your bloodstream and determine whether you are above the legal limit. In South Carolina, the legal BAC limit is 0.08 percent for drivers over the age of 21 and 0.02 percent for drivers under 21. For commercial drivers, the limit is 0.04 percent. Despite their widespread use, breathalyzer tests are prone to various errors and inaccuracies that can lead to false or misleading results.
Calibration and Maintenance Issues
One of the primary factors that can affect the accuracy of a breathalyzer test is the device’s calibration and maintenance. Breathalyzers must be regularly calibrated to ensure their accuracy. If a device has not been calibrated according to the manufacturer’s specifications or if it has not been properly maintained, the results it produces may be inaccurate. In South Carolina, law enforcement agencies are required to follow strict protocols for the calibration and maintenance of breathalyzer devices. Failure to adhere to these protocols can render the test results unreliable. Challenging the maintenance records of the breathalyzer used in your case can be a crucial step in disputing the results.
Operator Error
Breathalyzer tests must be administered by trained and certified operators. Improper administration of the test can lead to inaccurate results. In South Carolina, law enforcement officers must follow specific procedures when conducting a breathalyzer test. This includes ensuring that the test subject has not consumed any food, drink, or tobacco products for a certain period before the test, and that the test is administered correctly. If the officer administering the test did not follow the proper procedures, the results could be compromised. Examining the officer’s training records and the procedures followed during your test can help identify any operator errors that may have occurred.
Medical Conditions and Medications
Certain medical conditions and medications can affect the accuracy of breathalyzer test results. For example, individuals with diabetes may have higher levels of acetone in their breath, which can be mistaken for alcohol by a breathalyzer. Additionally, some medications contain alcohol or other substances that can interfere with the test results. If you have a medical condition or are taking medication that could have impacted your breathalyzer test, it is essential to provide this information to your attorney. A knowledgeable attorney can present evidence of your medical condition or medication use to challenge the reliability of the test results.

Environmental Factors
Environmental factors can also influence breathalyzer test results. For instance, exposure to certain chemicals or fumes, such as paint or gasoline, can lead to false positives. Additionally, mouth alcohol, which is alcohol present in the mouth rather than the bloodstream, can result in elevated BAC readings. Mouth alcohol can be caused by recent use of mouthwash, breath fresheners, or certain dental procedures. It is important to consider these environmental factors when challenging breathalyzer test results. An attorney can investigate the circumstances surrounding your test to determine if any external factors may have affected the results.
Breathalyzer Device Malfunctions
Breathalyzer devices are sophisticated machines that rely on advanced technology to measure BAC levels. Like any electronic device, breathalyzers can malfunction or produce incorrect readings due to technical issues. In some cases, the software or sensors in the device may be faulty, leading to inaccurate results. If there is evidence that the breathalyzer device used in your case was malfunctioning or had a history of producing erroneous readings, this can be a strong basis for challenging the test results. Your attorney can obtain records of the device’s performance and maintenance history to identify any potential issues.
The Importance of Legal Representation
Challenging breathalyzer test results in South Carolina requires a thorough understanding of the law, scientific principles, and the specific circumstances of your case. An experienced DUI defense attorney can provide invaluable assistance in this process. They can review the evidence against you, identify potential weaknesses in the prosecution’s case, and develop a comprehensive defense strategy. An attorney will know how to gather and present evidence effectively, including testimony if necessary, to challenge the reliability of the breathalyzer test results.

Building a Strong Defense
To build a strong defense against breathalyzer test results, it is essential to act quickly and gather as much evidence as possible. This includes obtaining maintenance and calibration records for the breathalyzer device, reviewing the training and certification of the officer who administered the test, and collecting any medical or environmental evidence that may have influenced the results. Your attorney will work diligently to uncover any procedural errors, device malfunctions, or other factors that could undermine the accuracy of the test results. By presenting a well-documented and compelling case, your attorney can increase the likelihood of a favorable outcome.
Potential Outcomes of Challenging Breathalyzer Test Results
Successfully challenging breathalyzer test results can lead to several potential outcomes. In some cases, the court may find that the test results are inadmissible as evidence, weakening the prosecution’s case against you. This could result in a reduction of charges or even a dismissal of the case. In other instances, the challenge to the breathalyzer results may be used to negotiate a more favorable plea agreement. Regardless of the outcome, challenging the validity of breathalyzer test results is a critical component of a robust DUI defense strategy.
The Role of Scientific Evidence
Scientific evidence plays a crucial role in challenging breathalyzer test results. Testimony from forensic scientists, toxicologists, and other specialists can help explain the limitations and potential inaccuracies of breathalyzer devices. These specialists can provide detailed analyses of the factors that may have influenced your test results, such as device malfunctions, calibration issues, and external interferences. By presenting credible scientific evidence, your attorney can cast doubt on the reliability of the breathalyzer test and strengthen your defense.
