Two people were rushed to the hospital after their SUV slammed into the back of a transport truck that had blown a tire and was stopped on the left shoulder of the eastbound 401 at Westney in Ajax.
As a result of the impact, the SUV rolled over and ended up on its roof across the eastbound lanes of the highway.
The female driver was ejected from the vehicle and was airlifted by Ornge from Lakeridge Health Ajax to a trauma centre with life-threatening injuries. A male passenger was also taken to the hospital with non-life threatening injuries.

“We are just trying to determine why the SUV driver was unable to avoid it and ended up colliding significantly with that stopped transport truck on the shoulder,” OPP Sgt. Kerry Schmidt said in a video update posted to twitter
