"FLEETSAFER" TO PROMOTE SAFE, LEGAL, AND RESPONSIBLE USE OF MOBILE DEVICES

IH Services, whose fleet of vehicles exceeds 1.5 million miles per year, was the first U.S. customer to implement the "FleetSafer" software program on all company cell phones. This software disables the text and email functions when operating a vehicle in excess of 5 miles per hour and only allows voice communications when using a hands-free device.
