This photo, taken Jan. 14, 2015, at the Fort Belvoir, Va., Express, shows the blue FuelCall sign, which indicates the gas pumps are equipped with a new call button system that allows drivers with disabilities to request assistance from a store associate with refueling. The Department of Defense authorized $1.12 million to install FuelCall assistance systems at military service stations on 370 Army, Air Force, Navy and Marine Corps installations worldwide.
