It appears the bus was traveling on Mount Wesley Road in Washington County, when the tires dropped off the right side of the roadway, the driver overcorrected and the bus overturned. It happened at approximately 3 p.m. (EDT).

Early information reveals that 67 students were on board; 22 were transported to Holston Valley, Johnson City Medical Center and Franklin Woods Hospital. The remainder of the students were transported by another bus to Mount Wesley Church for pickup.
