Does a failed Breathalyzer mean that you are automatically guilty? 

On Behalf of | Nov 10, 2021 | Drunk driving

Breathalyzer tests are frequently produced as a key part of the evidence in DUI cases. However, it is important to note that the technology is not always 100% accurate

Despite being one of the more accurate ways to gauge blood alcohol content, the test results of Breathalyzers can be skewed. Outlined below are some of the key reasons why failed Breathalyzer tests are not necessarily an automatic indication of guilt. 

Officers may have used equipment incorrectly

As with most technology, Breathalyzer tests need to be used in a specific way to give off the most accurate results. If an officer has not been sufficiently trained in the functions and processes of equipment, test results could be flawed. 

Medical conditions can impact results

Ailments such as diabetes may influence tests when no alcohol has been consumed. Breathalyzer tests typically register high levels of ketones in the blood as ethanol. However, diabetes in itself can raise the levels of ketones in the bloodstream, potentially resulting in inaccurate chemical test results.  

Day to day substances may contain alcohol

Drinking alcoholic beverages is not the only way to consume alcohol. Often, common items such as mouthwash and cough syrup may contain alcohol. When such products have been used before a test has been administered, the results could be impacted. 

Despite being frequently used in evidence, it is important to remember that Breathalyzer tests are not always accurate. If you find yourself facing DUI charges in North Carolina, guilt can not be assumed and you have legal rights and protections.
