We’re willing to bet that a lot of you would never get behind the wheel with so much as a single beer flowing through your system. No need for a breathalyzer, you’re not taking the risk, right? That’s commendable, and we thank you for keeping the roads safe, but do you exercise the same caution when it comes to driving tired? According to the NHTSA, the difference between driving while intoxicated and driving while drowsy isn’t as significant as you might think. In both instances, you’re seeing slower reaction time, poor attention to the road, and a greater potential for a serious accident.
