Driver inattention is the leading factor in most crashes and near-crashes […].
Nearly 80 percent of crashes and 65 percent of near-crashes involved some form of driver inattention within three seconds before the event. Primary causes of driver inattention are distracting activities, such as cell phone use, and drowsiness. (Source.)
Would you like to avoid crashing into someone riding a bike? Someone who is a son or a daughter, a brother or a sister, a dad or a mom?
Pull over and get some sleep if you’re drowsy. Wait until you’re stopped to change the CD or iPod playlist. Have someone else pick up the kid’s toy from the back seat.
Hang up and drive.
