Breathalyzers have become a common tool used by law enforcement agencies to determine if a driver is under the influence of alcohol. However, there are many myths and misconceptions surrounding the accuracy of breathalyzer tests in DUI cases. In this article, we will debunk these common myths and provide you with accurate information about breathalyzer accuracy.
Contrary to popular belief, breathalyzer results are not always accurate. There are several factors that can affect the accuracy of a breathalyzer test, including:
Calibration: Breathalyzers need to be regularly calibrated to ensure accurate results. If a breathalyzer is not calibrated correctly, it may provide false readings.
Operator error: The person administering the breathalyzer test needs to follow proper procedures and guidelines. Any mistakes made during the testing process can lead to inaccurate results.
Medical conditions: Certain medical conditions, such as acid reflux or diabetes, can interfere with breathalyzer results. These conditions can cause the presence of alcohol in the mouth, leading to higher BAC readings.
Environmental factors: Environmental factors like temperature and humidity can also impact breathalyzer accuracy. Extreme temperatures or high humidity levels can affect the reliability of the test.
Another common myth is that breathalyzer results cannot be challenged in court. However, DUI lawyers and attorneys are well-equipped to challenge these results based on how can a dui lawyer help me various factors:
Maintenance records: Your lawyer can request maintenance records for the specific breathalyzer used in your case. If there are any inconsistencies or issues with calibration, it could cast doubt on the accuracy of the test.
Operator training: Your lawyer may question the training and qualifications of the person who administered the breathalyzer test. If they were not properly trained or did not follow proper procedures, it can weaken the prosecution's case.
Rising blood alcohol defense: The rising blood alcohol defense argues that your BAC level was below the legal limit at the time of driving but increased by the time you took the breathalyzer test. This can be used to challenge the accuracy of the results.
Independent testing: Your lawyer may also request an independent test to be conducted using a different breathalyzer device. If the results from the independent test differ significantly from the initial breathalyzer results, it can raise doubts about the accuracy of the original test.
Contrary to popular belief, breathalyzers are not infallible. They are just one piece of evidence in a DUI case and should not be solely relied upon for conviction. There are several factors that can lead to inaccurate readings:
Mouth alcohol: Mouth alcohol refers to any residual alcohol in the mouth that can affect breathalyzer results. This can be caused by recent consumption of alcohol, using mouthwash or breath fresheners, or certain medical conditions. A DUI lawyer can argue that mouth alcohol contaminated the breath sample and resulted in a falsely high BAC reading.
Radio frequency interference: Breathalyzers operate on radio frequency technology, which means they can be susceptible to interference from external sources. A lawyer can argue that external radio frequency interference may have affected the accuracy of the test.
Blood-to-breath partition ratio: Breathalyzers measure the amount of alcohol in a person's breath and then convert it into an estimated blood alcohol concentration (BAC). However, this conversion is based on a standard blood-to-breath partition ratio, which may vary from person to person. Factors such as age, body temperature, and lung capacity can affect this ratio and lead to inaccurate readings.
False positives: Certain substances, such as mouthwash or medications containing alcohol, can cause a breathalyzer to produce a false positive result. Your lawyer can argue that these substances influenced the test results and challenge their accuracy.
While breathalyzer results are often used as evidence in DUI cases, they are not always admissible in court. A skilled DUI defense attorney can challenge the admissibility of breathalyzer results based on various factors:
Fourth Amendment violations: If the breathalyzer test was conducted without proper probable cause or without obtaining your consent, it may be considered a violation of your Fourth Amendment rights. Your attorney can argue that the results should be excluded as evidence due to this violation.
Chain of custody issues: Your lawyer can question the chain of custody of the breathalyzer device and the handling of the samples. Any gaps or inconsistencies in the chain of custody could cast doubt on the reliability and accuracy of the results.
Lack of certification: Breathalyzer devices need to be certified for use in DUI cases. If the device used in your case was not properly certified or expired, it can be challenged as evidence.
Unreliable brand or model: Some breathalyzer devices have been found to be unreliable or inaccurate. Your lawyer can question the reliability of the specific brand or model used in your case and argue that its results should not be admitted as evidence.
Q: Do I need a DUI lawyer to challenge breathalyzer results?

A: Refusing to take a breathalyzer test can have serious consequences, such as an automatic license suspension. However, it is important to consult with a DUI attorney before making any decisions regarding testing.
Q: Can I still be charged with a DUI if I pass a breathalyzer test?
A: Yes, it is possible to be charged with a DUI even if you pass a breathalyzer test. Breathalyzer results are just one form of evidence that law enforcement agencies use to determine impairment. They can also rely on other factors such as field sobriety tests and observations made by the arresting officer.
Q: How long do DUI charges stay on your record?
A: The length of time that DUI charges stay on your record varies depending on state laws. In some states, they may stay on your record indefinitely, while in others they may be eligible for expungement after a certain period of time.
