Being drowsy or “half asleep” can be compared to a drugged condition which can result in a fatal collision. It usually occurs from steady driving or from having started out tired. Be well rested before you begin your trip. If you start to feel sleepy, stop your vehicle and rest. If you must park by the side of the road, pull well over and put on your four-way flashers to prevent being struck. If possible, stop at a rest area, motel or hotel.
