Most people know that if they are pulled over while driving because they are suspected of being under the influence of alcohol, they will probably have a breathalyzer test administered to them. However, it is important to understand what can affect the results of breathalyzer tests. Why? Mainly because if you're not under the influence of alcohol, but the breathalyzer indicates that you are, you can still be arrested.
With that in mind, take stock of the common items that can affect a breathalyzer test. They include some kinds of cough syrup, mouthwash and breath mints. Taking some of any of those can make a breathalyzer indicate that your blood alcohol content exceeds legally allowable levels for individuals driving a motor vehicle. You might be arrested because of that, even if you haven't had a single beer and are capable of driving safely.
