Ha ha, funny you should put a picture of scaffold up.
A Dude I worked for used to load his 2wd Ranger pickup up with scaffold until the front wheels left the ground, then throw a few bits off to drive it to site on a regular basis, always got away with it.
The plod pulled him over one day with two bags of cement in the back, and put him over the weighbridge.
The 25kg, written on the bags, and the weight plate on the truck meant nothing to them.
Having said that, they could have just been shooting him a warning.
