School bus Photo: 123rf.com Two children were seriously injured and six others suffered minor injuries after a school bus crashed near Murchison this week. Murchison Area School principal Andy Ashworth said the bus was taking children home when the crash happened and was in an area with little signal. Last week four school students were injured after two buses crashed in Christchurch. St John clinical director Dr Tony Smith said ambulance officers were often the first to arrive at the scene and see first hand the devastating impact of crashes especially when passengers were not wearing seatbelts. "Our view that seatbelts on buses of an agreed definition should be compulsory remains unchanged; we believe safety belts should be worn to prevent fatalities and serious injuries including fractured and amputated limbs.
