A dash cam footage shows a tractor-trailer fall off a ramp and onto a busy highway, striking two vehicles, in Toronto earlier this week.

According to CTV news, a Canadian news station, the accident happened around 3:30 in the afternoon on March 24th. The driver of the trailer somehow lost control of his vehicle on Highway 401 and fell over the ramp onto Highway 404.

None of the car drivers were injured but the driver of the tractor-trailer was sent to the hospital with minor injuries. The lanes were closed for hours while the wreckage was cleaned up.

The cause of the accident is yet unknown but is currently under investigation.
