Danger: Cell Phone Driver
by Hank Upp

A law should be passed that bans the use of a cell phone while driving. Too often I have seen people driving recklessly while engaged in conversation on a cell phone. They can't seem to find time to exercise proper vehicle functions or safe driving procedures because they are too busy gabbing on their phones. One hand holds the phone to the ear, and the other hand is used to steer. In fact, a study has shown that more accidents are caused by people using cell phones while driving than by people who are drunk while driving. The need for restricting cell phone use is clear. These careless people are endangering you and me on the public streets, and I believe the time has come to call for an end to this needless and potentially dangerous practice.
