When under court Order to use an ignition interlock system, a mouthwash interlock false positive can violate your probation. Because this is so important, you need to know to avoid this issue.
Avoiding Mouthwash Interlock False Positive
While it may be surprising, many mouthwashes contain significant amounts of alcohol. In fact, you actually have to look for “alcohol free” products to avoid it. Consequently, we list here some of the most common brands and how much alcohol they contain. For example, Listerine Total Care contains 21.6% alcohol (42 proof). Furthermore, even the Listerine Naturals had the same amount. But it goes further. Even Cepacol, the #1 brand in hospitals, had 14% alcohol (28 proof). So how do you prevent mouthwash interlock false positive test results? Probably the safest way is to just have stale breath. Another way is to use an “alcohol free” brand (Crest Pro-Health) and rinse with water before testing. Since so much is at stake, it is best to safe than sorry.
So What Happens If You Violate
Because of potential DMV and court Order issues, we discuss both. First, you get a DMV letter stating your license is suspended. But you can file a written appeal claiming an error or mistake. In addition, you may have violated your probation conditions. Consequently, a District Court judge could revoke your probation and put you in jail. Hence, you need to be extra careful to avoid things that can cause false positives. Much as you may try, however, let’s not forget interlock devices are imperfect machines and can fail.
So what do you do if you find yourself in trouble? Almost certainly you should retest quickly so that you can show you were not drinking. Rather, a quick retest showing negative is best evidence of machine error. In addition, it demonstrates you are following the rules and staying compliant. And in the end, that’s what really matters. In conclusion, if you have any doubt, rinse your mouth with water and wait at least 15 minutes before testing. Maybe best to test later than take a chance.
