Car breathalyzers and ignition interlock devices are widely used today as a result of a DUI or other drunk driving conviction. The fuel cell technology that is approved by the U.S. Government in the devices is complicated, of course, but the devices themselves have one simple purpose: to keep drunk drivers off the roads. That translates into one very simple trigger for setting off an ignition interlock device, alcohol, which means there are few things that will complicate the ignition interlock test. Most of those complications come down to a person who has been drinking alcohol.
Alcohol sets off an ignition interlock device, whether it is alcohol in beer, wine or liquor or the alcohol in mouthwash or some medications. The differences in those types of alcohol is how quickly the mouthwash alcohol dissipates from your mouth. Plus, binge drinking those kinds of minty flavors will probably just leave you feeling sick, not drunk, and not a danger on the road. So, if your ignition interlock is set off by mouthwash, you just have to wait for your next re-test opportunity (usually, just a few minutes later), and you should be good to go. You’re even safe to eat beer-battered food and dishes that are cooked with wine, since the intoxicating effect of alcohol is burned off during the cooking process and all you’re left with is the flavor.
The alcohol and risky behaviors that led to your drunk driving conviction and your ignition interlock will obviously set off the device. That’s the purpose of an interlock and most violations come down to a person who has been drinking alcohol and then try to drive. Ignition interlock devices are simple to use and ask one simple thing from you; that you don’t try to drive under the influence of alcohol. There’s nothing complicated about that.
