text: Firstly, driving requires your full attention, but phones compromise this focus. You need to keep both hands on the steering wheel to be the most effective driver. But, every time you text, read messages or talk on a cell phone without a hands-free device, not only is your focus compromised, but you can't keep both hands on the wheel. Phone use when you are driving can also affect your alertness of the surroundings, which can make you prone to collisions. Also, distraction and inattention are the number one cause of traffic accidents and it is estimated that nearly every collision involves one of these two related errors. Driving takes all your attention and it is your responsibility to keep your eyes on the road, so put down the phones and pay attention to the road.
