it happens to everyone from time to time. Whether you drive a car or a commercial truck. We all get fatigued sometimes.
It can happen because we had a terrible night’s sleep, or we ate the wrong foods for lunch. And all of a sudden, our eyes are getting heavy, our heart rate slows, and we start dossing off. Those microsleeps. Your chin drops and hits your chest, and you are temporarily jolted awake. Only to have that feeling come over you again. Your eyes get heavy and you know you had better do something. But what???
I came across this article recently and it is full of suggestions for both the commercial drivers and the car drivers.
