Do you have cell phone policies for your employees? Driver distraction contributes to 20 percent to 30 percent of all crashes, according to the National Highway Traffic Safety Administration (NHTSA) - and a recent NHTSA survey finds that nearly 75 percent of drivers are taking a risk by using their phone while driving.

Conversing on cell phones while driving disrupts the driver's attention to the visual environment, leading to "inattention blindness," or the inability to recognize objects encountered in the driver's visual field.
