Residual Mouth Alcohol and Your Breath Test
Many of the Twitter trolls that harass me every time I succeed in anImmediate Roadside Prohibition or impaired driving case appear to believe that innocent people do not receive DUI charges. This could not be farther from the truth. I have personally seen how a person can provide a falsely elevated result just from a few drops of alcohol consumed in recent proximity to the test.
This phenomenon is known as residual mouth alcohol. And it can affect the reliability of an approved screening device (or, roadside breathalyser) test. But it can also affect the reliability of a breathalyser at the police station, even where the instrument has a mechanism designed to eliminate it.
The video above shows how mouth alcohol falsely skews the results. I do not want to spend much time on the process, but more on what I have seen and where mouth alcohol can come from in affecting a breath test.
