Yeah i Slept once while driving,that too it was evening,at that time i had 6 months of driving experience,and was my first drive to native,on NH-17,mumbai-goa highway(head on traffic condition).I ate light lunch,as my dad use to do,rest excluding my dad has dozed off.i don`t know what happened but i was feeling sleepy,and i closed my eyes and something weird happened,An opel corsa,white color(do remember it quite well),was honking aloud,flashing.Later do i realized that i was on the wrong lane(opposite)
,and poor corsa guy pulled his car outside the road or it would be fatal accident.Dad asked me to pull of the car and later asked me to wash my eyes,and he drove the later journey.Since then dared not to sleep even at long odd hours..
My advise would be:
-Just when you feel tired, pullout somewhere,wash your face and walk for 50-100meters from the car,do some little exercise to keep warm(stretching legs,arms,neck exercise).
-Feeling sleepy,pullout,take a power nap.
-Avoid night journey(especially long once) if possible.
-Try to cover most distance in day time.
-Chat with your Co-passenger,sitting besides,ensure that he\she doesn't sleep.(Always works)
-Drink plenty of Water.
-Specially during nights,drive at safe speed, doesn't matter if you reach a hour late.
-Ensure your alert,and keep eye on reckless drivers.
-Listen to your favorite music,try to sing.
-Use low beam.
