On October 11, 1975, about 9:05 a.m., a charter bus owned and operated by the Metropolitan Coach Corporation was eastbound, in heavy rain, on Interstate 495 in Bethesda, Maryland. As the bus negotiated a curve to the right at 50 mph, the rear wheels of the bus lost traction and the rear of the bus began to slide from side to side. In its final slide to the right, the bus rotated counterclockwise 160 deg and contacted the guardrail. The bus rolled over, rotated 270 deg about its longitudinal axis, and landed on its left side in a roadside ravine. Of the 29 bus occupants, 26 were injured. The National Transportation Safety Board determines that the probable cause of this accident was the inadequate frictional coefficient between the tires and the pavement; the frictional coefficient could not resist the centrifugal force of the bus as it traversed the curve at the posted speed limit.
