New video footage has emerged following a massive pileup on the 401 east of Toronto on Saturday.
Provincial police say around 100 vehicles were involved in crashes in the Bowmanville area, after poor weather conditions left the highway snow covered and slick.
The video, posted on YouTube, shows cars struggling with the poor conditions and a jack-knifed transport truck crashing into multiple vehicles after losing control.
Police say no one was killed in the collisions, but several people were taken to hospital with minor injuries and released.
Both directions of the 401 were closed for several hours in Bowmanville while vehicles were removed and the road was plowed.
The OPP is reminding motorists to take the time to prepare themselves and their vehicles for safe winter driving. They say defensive, responsible driving is crucial to reducing fatalities and serious injuries on our roads, especially during the winter months. Motorists are being asked to stay focused on the road and on other vehicles, and to eliminate all distractions.
