Our camp is being given a 22-passenger bus. This is the style common to churches and daycare operations. The bus does not have seatbelts for passengers. We have been researching the issue and cannot find a firm consensus pro or con on this issue. Anyone have experience in this area? Also, are there any established resources (e.g. NTSB) that I could reference in supporting our decision to use/not use seatbetls?
