Trucking industry companies now have a bit longer to locate and purge potentially harmful telecommunications equipment manufactured by five Chinese companies that may be in use in their operations. On Aug. 12, John Ratcliffe, the director of national intelligence, extended the deadline from Aug. 13 to Sept. 30 for all federal contractors to be compliant with the law or risk possible debarment as a contractor if they cannot ensure the components are not present in their systems. The five companies targeted -- Huawei, ZTE Corp., Hytera, Hikvision and Dahua Technology -- are believed to be potential hackers into U.S. intelligence and defense agencies’ information systems.
