Don't Fall Asleep at the Wheel
If you experience any of these danger signs of drowsiness, pull off the road and take a nap -- in a safe, well-lighted area, if possible.
Your eyes close or go out of focus by themselves. You have trouble keeping your head up.
You can't stop yawning.
You have wandering, disconnected thoughts. You don't remember the last few miles.
You drift between lanes, tailgate or miss traffic signs.
You keep jerking the car back into the lane.
You have drifted off the road and narrowly missed crashing.
