If you are facing a DWI charge, a breathalyzer may have played a role in you being charged in the first place. This handheld device that you may have been required to breathe into is intended to measure your blood alcohol concentration (BAC), and a reading of .08 percent or higher puts you over the legal limit. The fact of the matter is, however, that the readings breathalyzers produce are not always accurate, and better understanding some common inaccuracies can help you build your strongest defense.

One: The Breathalyzer Is Not Properly Calibrated

The breathalyzer itself is a complicated piece of machinery, and if any one part is malfunctioning, it can significantly skew the results obtained. As such, police departments and police officers are required to ensure that the breathalyzers that they are using are regularly calibrated to help ensure accurate results. Your criminal defense attorney may decide to subpoena the records related to calibration and maintenance for the device that was used in your arrest.

Two: The Breathalyzer Was Administered Incorrectly

Police officers are required to be ready to take care of business in both of the following arenas when it comes to using the breathalyzer:

  • To be well trained in the breathalyzer’s administration

  • To know and follow the strict guidelines they must adhere to in the administration of the breathalyzer

If the officer who arrested you was poorly trained in using the breathalyzer and/or failed to follow proper procedures in its use, it can significantly affect your case. It is a good idea to jot down everything you remember about the officer’s implementation of the testing procedure and about your arrest in general as soon as you are able to do so – because the information you capture could prove invaluable as your case proceeds.

Three: You Ate Something that Skewed the Results

When we eat and drink, all kinds of chemistry happens in our bodies, and if you eat or drink something that is especially sweet or starchy, it can coat your mouth and/or stick to your teeth and ultimately create what is known as mouth alcohol. While the level of actual alcohol involved is very low, it is in your mouth, which means that it is blown directly into the breathalyzer – which, in turn, means that it can skew your results. Low-carb diets have also been known to taint the results of breathalyzers. If your diet is very low in carbohydrates, your body can produce ketones as a result, and these ketones can trigger a false positive on the breathalyzer.
