This research has been carried out because drowsiness has played agreat part in road accident casualties especially in passenger transportation section and is based on library studies. Due to fieldwork limitations, results of other researchers have been used. The present research concludes that we don’t have enough information about various methods of avoiding drowsiness when driving.
