One vehicle was in an almost vertical position, sandwiched between a car and a hatchback, after a pile-up on Highway 417 sent the car underneath it.

It happened in the left lane of Highway 417 westbound, just past Boundary Road, during Friday morning's rush-hour commute, according to OPP.

No major injuries were reported.

People on the highway tweeted pictures of the crash:
