Ontario Provincial Police (OPP) officers with the Highway Safety Division have reopened the eastbound lanes of Highway 401 at James Snow Parkway in Milton after a multi-vehicle crash that sent one person to hospital with life-threatening injuries on Monday.
OPP Sgt. Kerry Schmidt said the crash happened when a vehicle travelling eastbound tried to merge into the express lanes and crashed into the entry cushion that separates the collectors and express lanes.
“That sent the vehicle out of control into the path of an eastbound tractor-trailer,” Schmidt explained.
He said two people were in the vehicle, and the driver was taken to hospital with serious, life-threatening injuries. The passenger had minor injuries.
Schmidt later said officers received reports of aggressive driving before the crash. However, the investigation is still ongoing.
Four vehicles in total were involved in the crash, which happened just before 5 p.m.
According to a post on the Ontario Ministry of Transportation’s 511 social media account just after 11:10 p.m., the highway lanes were cleared.
