This incident involved a school bus traveling westbound and a tractor traveling eastbound on a non-divided, two-lane roadway. The front left of the school bus was contacted by a farm implement which was being towed by the tractor. The collision occurred just beyond the crest of a hill. ARCCA’s accident reconstruction team was tasked with determining which vehicle crossed into the opposing lane of travel.
Roadway evidence, including gouge marks from the chisel and tire marks from the bus, was captured at the scene.
