The latest information available to my Department regarding the maintenance record of the vehicle in question since 1998 is given in the following statement. The narrow country roads and pot-holed terrain, over which school buses typically travel, subject the coaches to considerable structural stress, which is a contributory factor in their failure rate. When the bus was off the road, for any reason, other arrangements were made to ensure that the service operated. This vehicle was included in a programmed schedule of preventative maintenance procedures, designed to keep these occurrences to a minimum.
