Ontario Provincial Police issued a warning to the driver of a transport truck they say is responsible for the collapse of an elevated sign on a major highway Friday morning.
Authorities say just before 8 a.m., a truck struck the sign on Highway 401 near Brock Street in Whitby, causing it to "bend and collapse."
"You can see the impact mark here on the sign where a transport truck hit the sign and part of the crossbar here as well," OPP Sgt. Kerry Schmidt said in a social media post.
Images from early Friday morning show the sign on the other side of the road, completely blocking traffic. As a result, a long line of cars was stuck on that stretch of road.
