A driver and his passenger are lucky to be alive after a piece of plywood smashed into their windshield on Highway 410.

Emergency crews responded to reports of a collision southbound at Queen Street East on Highway 410 in Brampton around 4 p.m. on Wednesday.

"A loose piece of wood that was unsecured flew off another truck and struck another vehicle," says Sgt. Kerry Schmidt.

Tow truck driver Rawad Sawah ​extracted the wood from the windshield and tells CBC News the incident could've been a lot worse.

"The plank fell right between the front seats of the car and it looked like it just missed the driver. I guess they got really lucky to not be seriously hurt," Sawah said.

Paramedics transported a man and woman to hospital with minor injuries.

Police are reminding drivers to ensure materials being transported are strapped and properly secured.
