About 12:20 p.m. on March 13, 1985, an Ashe County School District schoolbus driven by a 17-year-old student driver and carrying 22 students, ages 16 and 17, was traveling up an 8-percent grade on eastbound State Route 88 near Jefferson, North Carolina, when it went off the right edge of the road in a left curve and crossed the grassy shoulder. The 1980 schoolbus then rolled one revolution to the right and down a steep embankment and came to rest upright 24 feet below the road surface against two trees. There was no fuel leakage or fire. It was daylight the weather was clear, and the two-lane roadway was dry. One student was seriously injured, one sustained moderate injuries, and the other 20 had minor injuries; the schoolbus driver was not injured. None of the bus occupants were ejected from the schoolbus.
