The driver of a tractor-trailer that overturned, crushing an SUV but leaving its occupant "miraculously" alive was charged with careless driving, Ontario police said on Wednesday.

Ontario Provincial Police charged the 52-year-old driver after his tractor-trailer flipped onto its side while on Highway 403 near Oakville, Ont., Monday afternoon.

The truck forced a Mazda CX7 off the road and into a ditch, before landing on top of the SUV and trapping a 38-year-old driver.

The driver, Edyta Tobiasz, survived the crash but was pinned in her vehicle for more than two hours as emergency crews rushed to pull her from the wreckage.

"I feel scared and then I see the (trailer) fall down on my car. That is it," Tobiasz told CTV Toronto on Tuesday. "It was just a second. I didn't have time to do anything."

As rescue crews were working to save her, Tobiasz managed to find her cell phone and called her husband.

"I think, thanks to God, I am alive. I thank God for my second life," She said. "It is a miracle."

The driver of the tractor-trailer, from Mississauga, Ont., has been charged with careless driving under the Highway Traffic Act.
