Never drive sleepy. If you have heavy eyelids, you are not fit to drive.


Drowsy Driving – you can’t fight sleep – TAC ad

Drowsy driving is at least as dangerous as illegally driving under the influence of alcohol (Powell, Schechtman, Wiley, Li, Troell, & Guilleminault, 2001). Staying awake for 19 hours produces impairment similar to having a BAC of 0.05. Being awake for 24 hours is comparable to having a BAC of roughly 0.10 (Dawson & Reid, 1997).

According to a recent report by AAA Foundation for Traffic Safety, “More than two in five drivers (43.2%) admitted having fallen asleep or nodded off while driving at least once in their life.”


Drowsy Driving Signs

If you find that you are too sleepy to drive, the best thing to do is get a full night’s rest. If that’s not possible, take a 20 minute nap or drink 2 caffeinated drinks (each with as much caffeine as a cup of coffee).
