RCMP say a chain-reaction crash northeast of Calgary that killed a road worker was caused by a transport truck that failed to stop at a posted stop sign.

Police say that the truck was travelling north on Highway 21 when it went through the stop sign at the intersection with Highway 9 and crashed into a Honda Civic at about 12:30 p.m. Monday.

The two vehicles then crashed into a Chevrolet Silverado pickup truck parked at the side of the road just north of the intersection.

Two workers who were doing highway maintenance on Highway 21 were hit by the vehicles and one of the workers, an 18-year-old man from Three Hills, was killed.

The transport truck eventually came to rest over 80 meters away in a field.

The other worker, a 19-year-old female also from Three Hills, was air lifted by STARS to hospital in critical condition and remains in intensive care.

The person in the Honda was taken by EMS to hospital and has since been released.

Police say charges are pending against the driver of the transport truck.

The 35-year-old man, from Blackfalds, could be facing the following charges:

  • 1 count of Dangerous operation of a motor vehicle causing death
  • 2 counts of Dangerous operation of a motor vehicle causing bodily harm
