The driver of a Chevrolet Silverado was pulled over in Norfolk County, about two hours west of Toronto, Ontario, for using his truck to tow a full-size semi-truck trailer.

Photos posted by the Ontario Provincial Police on their Facebook page show the 53-foot trailer was attached by a crude pin system, which somehow took the weight and stress without breaking.

The vehicle also had a rudimentary air braking system installed, but it appears to only be hooked up to run the lights, not the brakes themselves. This means the truck’s brakes may have been stopping the entire weight of the trailer.

The vehicle pulling the trailer was a mid-2000s Chevrolet Silverado, and it wasn’t even a dually. The tow rating for a 2003 Chevrolet Silverado is at most 8,600 pounds, and as some keen commenters have noted, a trailer that size weighs about 12,000 pounds unloaded — and who knows what he was carrying.
