Ottawa Now - Wheel dislodges from truck carrying a trailer, causing lane closures but fortunately no deaths

The wheels on a truck, hauling a trailer, were going round and round on the Queensway yesterday morning. That is, until one of them flew off and caused a bunch of lane closures. To add another dose of fear to the rural chaos, a Bobcat vehicle was being housed inside the trailer when the accident took place. Miraculously, nobody was injured, but charges are now pending against the company that owns the truck. How does something like this happen in the first place? How can we prevent this scenario from happening more often? Kristy Cameron picks the brain of Simon Potten, a master mechanic who used to host CFRA’s Drivability.
