Driving while using a cell phone is a dangerous distraction that should be illegal. It contributes to a significant number of motor vehicle accidents and deaths each year. Even hands-free use requires dual-task processing that takes attention away from safe driving. While some argue banning cell phone use won't stop all accidents, it could prevent thousands of deaths annually by reducing this major cause of distracted driving. For safety and policy reasons, all states should prohibit any cell phone use behind the wheel.
