One of the parents outside Rhws Primary School this morning told ITV News: "You just feel lucky it wasn't you."
Martin Rauch said the Rhoose collision occurred on the same route his family walks to the school.
"We go down that side of the road," he said.
"We cross at that crossing, with that lollipop lady. It could easily have been us."
He added that the community was in 'a state of shock'.
Five adults and four children have been taken to hospital with injuries.
