If you have been pulled over and asked to take a breathalyzer test, you might wonder whether the results are always accurate. The truth is that several factors can potentially affect the reliability of these tests. Understanding what might influence your breathalyzer results could be important if you are facing driving under the influence (DUI) charges.
Medical conditions and substances could interfere with the results
Your body chemistry and certain medical conditions might impact breathalyzer readings. For instance, if you have diabetes, your body may produce acetone. Some breathalyzer devices could potentially mistake this for alcohol. Similarly, individuals with acid reflux or GERD might experience residual alcohol in their mouth and throat. This could lead to elevated readings.
Certain medications and products containing alcohol, such as mouthwash, breath spray or cough syrup, might also affect test results if used shortly before testing. Even some diets, particularly low-carb or ketogenic diets, can cause your body to produce compounds that may register on a breathalyzer.
Device calibration and administration issues
Breathalyzer devices need regular care and proper setup to work correctly. If the device has not been set up according to the manufacturer’s instructions or state rules, it might give wrong results. The officer giving the test must follow specific steps, including watching you for a certain time before testing to make sure you haven’t consumed anything that could affect the results.
Outside factors can also play a role. Very hot or cold temperatures, radio wave interference and even certain chemicals in the air might impact how well the device works. Additionally, if you did not give a good enough breath sample or the officer didn’t administer the test correctly, the results could be questionable.
What you should consider
If you believe your breathalyzer results were inaccurate, you must understand your rights and options. You can question whether the device was properly maintained, if the officer followed correct procedures and whether any medical conditions or other factors might have influenced your results. Knowing these possibilities can help you better understand your situation and the choices available to you.
