A boy who jumped from a school Go Bus in Hawke's Bay has been taken to hospital in a serious condition.
A St John ambulance attended the scene at 3.38pm on Friday.
According to a bystander the boy was meant to get off the bus in Waipawa for a doctor's appointment.
"He forgot, hit emergency stop and, as the door opened, he threw his bag out and jumped after it."
Passengers heard a thud and saw him roll into gutter, the bystander said. Motorists immediately stopped and ran to the boy.
Another bystander said the boy was unconscious.
The bus was seen to stop about 500m down the road.
