I am not sure about that. From http://www.nsba.org/site/view.asp?TRACK ... &DID=11411sparx wrote:And yet school bus seatbelts aren't even an option so just about every school bus accident, though perhaps not many in number, are high in injuries/casualties.
Each year, approximately 800 school-aged children are killed in motor vehicle crashes during normal school travel hours. This figure represents about 14 percent of the 5,600 child deaths that occur annually on U.S. roadways and 2 percent of the nation’s yearly total of 40,000 motor vehicle deaths. Of these 800 deaths, about 20 (2 percent) are school bus–related—5 school bus passengers and 15 pedestrians. The other 98 percent of school-aged deaths occur in passenger vehicles or to pedestrians, bicyclists, or motorcyclists. A disproportionate share of these passenger vehicle–related deaths occur when a teenager is driving—approximately 450 of the 800 deaths, or 55 percent.
At the same time, approximately 152,000 school-age children sustain nonfatal injuries during normal school travel hours each year. More than 80 percent (about 130,000) of these nonfatal injuries occur in passenger vehicles; only 4 percent (about 6,000) are school bus–related (about 5,500 school bus passengers and 500 school bus pedestrians), 11 percent (about 16,500) occur to pedestrians and bicyclists, and fewer than 1 percent (500) are to passengers in other buses.
....school buses represent 25 percent of the miles traveled by students but account for less than 4 percent of the injuries and 2 percent of the fatalities.
