Three people are in hospital after a three-vehicle crash near Dalmeny involving a school bus.

Emergency crews were called to the collision, about 1.5 kilometres south of the central Saskatchewan town, at about 3:30 p.m. Friday.

A minivan struck the back of a southbound school bus before being hit by a pickup truck, RCMP said in a media release.

A 46-year-old woman driving the van was taken to hospital in Saskatoon by STARS air ambulance with serious injuries, while a six-year-old girl and a 40-year-old woman in the truck were transported to hospital by ground ambulance in stable condition.

One of the injured people had to be extricated from one of the vehicles by emergency crews, according to MD Ambulance.

All 10 children on the bus as well as the driver were not injured.

The 46-year-old woman was the lone occupant in the van.
