Witnesses say the plywood came flying off a small utility trailer being towed by an SUV on Highway 410 in Ontario

Just moments after watching a piece of plywood soar through the air and smash into her windshield, Jaspreet Sran stopped, stepped out of her car and assessed the damage.

"I started shivering," said Sran from her Brampton home. "I realized, 'Oh my God,' this thing has happened."

During the afternoon rush on a busy Toronto-area highway, Sran looked on in shock at the large piece of plywood sticking straight out of her windshield. One of its corners had pierced the glass and struck her in the arm.

Sran, who was driving with her mother-in-law and a family friend, remembers watching the plywood in the air for between 10 to 15 seconds before it eventually landed on her Volkswagen Jetta.

She and her friend were covered in broken glass, and her mother-in-law had her hand cut in the back seat.

"When the call came in that there was a vehicle blocking a live lane that had a piece of wood that had gone through the windshield, you think the worst," said Sgt. Kerry Schmidt of OPP.

"This could have been so much worse," he added.
