When emergency responders were called to a grass fire near the Tilbury 401 rest stop, they discovered an unexpected cause.
The investigation determined two wheels had come off the rear passenger side of the trailer on a tractor trailer unit.
According to police, the overheated wheels had rolled into the nearby field, starting the fire.
The incident happened in October 2016, but now a 64-year-old Chatham man is charged with driving an unsafe commercial motor vehicle.
