Preliminary investigation has determined that two SUVs had stopped on the shoulder of the north bound left lane, possibly due a mechanical failure of one. A north bound minivan clipped the rear SUV before colliding with the second stationary SUV at highway speed, pushing this SUV down into the median. The minivan deflected to the right and struck an enclosed utility trailer being pulled by a pickup in the right lane. The minivan came to rest blocking the left lane.
As additional Emergency Responders arrived, the north bound traffic on the QEII Hwy was diverted onto an adjacent gravel side road for safety. This diversion lasted just under 2 hours.
The female passenger of the SUV had to be extricated from the vehicle by Fire / Rescue. She and the female driver were transported to the Foothills Hospital in Calgary by EMS. Both have since been treated and released.
The occupants of the minivan, an adult male, adult female and 4 male youths between 4 and 9 years of age were transported by EMS to Olds Hospital. All were treated and released.
The two males in the SUV initially clipped + the male driving the pickup pulling the trailer were uninjured.
Speed, alcohol and road conditions do not appear to factors in the collision. All occupants appear to have been wearing seatbelts, or to be riding in the proper child seats. Air bags also deployed as designed.
Attending members would like to especially thank those that stopped at the collision scene to assist the injured prior to the arrival of Emergency responders. Also they stuck around and provided contact information for statements after the soaking rainstorm hit.
