On Saturday, July 2, 2016, about 5:16 a.m., a 1979 Blue Bird bus, operated by Billy R. Evans Harvesting, Inc., of Belle Glade, Florida, was traveling south on State Road 363 (SR-363), near St. Marks, Florida. The bus was occupied by a 56-year-old driver and 33 passengers, most of whom were migrant agricultural (AG) workers. As the bus driver approached the US Highway 98 (US-98) intersection, he did not stop at the stop sign and overhead flashing red traffic control beacons, entered the intersection, and was struck by a westbound 2005 Freightliner truck-tractor in combination with an enclosed semitrailer. The truck-tractor—occupied by a 55-year-old driver and a passenger—was operated by Verity Van Lines, Inc., of Seaford, New York. Overhead flashing yellow traffic control beacons controlled westbound traffic on US-98 at the intersection.
The front of the truck-tractor struck the left side of the bus slightly behind its front axle, resulting in the rapid counterclockwise rotation of the truck-tractor and the breach of its right-side-mounted diesel fuel tank—which ignited a fire. The front of the semitrailer then struck the left side of the bus near its rear wheel area as both vehicles proceeded toward the southwest corner of the intersection. Prior to coming to rest, the vehicles collided with fixed roadside objects, including a utility pole and its supporting cables. As a result of the crash, the truck driver and three bus passengers died. The bus driver, 28 bus passengers, and a passenger in the sleeper berth of the truck sustained injuries of varying degrees.
