A Christchurch bus company says it is at a loss to explain why one of its drivers tried to drive a school bus under a low railbridge, smashing the windscreen and injuring several children.
The bus was taking 24 pupils from Woolston School and several adults to a cross-country event at Ferrymead Park when it hit the the bridge on Richardson Tce at 9.15am.
The bus, about 2.9m high, tried to clear the 2.4m bridge, causing the front windscreen and one side window to shatter, said police.
Seven children aged 9-12 were taken to hospital with cuts, bruises and other minor injuries, and the others were returned to school where they would receive counselling, said Sergeant Richard Ryan.
The driver was shaken but injured.
