Sometimes you’re out at a bar (while having a breathalyzer like the BreathKey Keychain Breathalyzer, I hope) and you’ve only had one beer or drink. Unless you’re an extreme lightweight, one drink shouldn’t really do much to alter your driving ability. However, sometimes that beer or drink can be enough for a cop to feel suspicious about it if they were to pull you over. We beg that you not drive if you absolutely can’t. If you’ve only had one beer, here a couple tips that can help make a cop feel not so suspicious if they pull you over. First, always have gum in your car. Cops can usually smell the presence of alcohol pretty easily even though you’re way under the limit. Use gum to control some of the odor. Next, roll down your windows for about 30 seconds or so when you’re driving. In case the bar was full of smoke, it’s probably all over your clothes, you’ll want to air that out as much as you can.
