DUI myths coming. Can you beat a breathalyzer by sucking on a penny? That's not true. It's a myth. It doesn't work. The idea is something about the metals of a penny can help you beat a breathalyzer. Don't fall for that. Now, if you're a follower of Dr. Judge, you already know what to say when a police officer offers you a breathalyzer, and that is, I don't take tests without a lawyer. So, if you've had a few too many to drink and you find this penny on the sidewalk right before you get arrested, please don't put that in your mouth.
