What products might cause inaccurate Breathalyzer readings?
Some mouthwash and breath sprays can contain alcohol. Because the device cannot determine the source of the alcohol – whether it came from beer, liquor, mouthwash, etc. or from the lungs or the mouth and throat – the test may indicate impairment incorrectly. It doesn’t actually render a false positive for alcohol because it does detect it, but the source may be called into question by a Ft. Lauderdale DUI attorney in some cases.
Similarly, a breath test may detect alcohol from cough syrup and other medicines. Instead of detecting alcohol from the lungs, the test may detect alcohol present in the mouth and throat from these products. Again, this isn’t a false positive for alcohol, but the source of the alcohol isn’t detected, and a lawyer may question the results.
Some drivers have been wrongly accused of drinking and driving because of alcohol-containing products like mouthwash and cough syrup that can affect a breath test. (Of course, drinking mouthwash can cause an individual to become impaired.) Those wrongly accused of drinking and driving due to inaccurate Breathalyzer readings influenced by other sources than alcoholic beverages should contact a Ft. Lauderdale DUI attorney who can assess the situation and determine the next steps.
Addressing Inaccurate Breathalyzer Readings with a Ft. Lauderdale DUI Attorney
While cough medicine or breath fresheners alone may not cause BAC to rise above .08 according to a chemical breath test, it may add to the test’s readings. If you’ve been drinking previously, but your BAC is below legal limit, adding alcohol to the mouth or throat area might affect the readings.
Talk to your attorney about factors that might have affected your chemical test because these issues, along with other evidence that may indicate you were not intoxicated, may be presented in a defense against DUI charges. Testimony from others who were with you prior to the traffic stop, your behavior during the traffic stop and the circumstances of the arrest might also be used as evidence in your defense. Improper use or calibration of the actual Breathalyzer device also may be evaluated.
