A man in Canada sustained serious head injuries in a four-car accident when the vehicles hit tires that flew off a garbage truck. http://www.cbc.ca/canada/toronto/story/2010/04/20/runaway-tires.html
The crashes took place at 4:30 a.m. on Highway 403 near Dundas, Canada. The 23-year-old driver of a Suburu sedan involved in the crash suffered bad head injuries when he was thrown from his vehicle. He was air-lifted to a hospital.
Police said that the incident happened when cars struck a pair of runaway tires that came off the garbage truck. The drivers involved in the crashes couldn’t see the tires in the predawn darkness.
After a series of fatal accidents a few years ago, at least one province in Canada put in place larger fines against trucking firms for accidents caused by runaway tires.
