I have never heard of a CT being weighted unless its to register for a tare weight . If you went silly & it looked really heavy , over the top it might happen to improve the list of charges against you . Mostly cause we not a commercial transport they have got bigger fish to fry . Some of them are huge to . From time to time there is a blitz on caravans & the like but how often do you reckon you would be heavy anyway ?
If you want Brownie points find a closed weigh bridge in your travels . Pull up on it lean over & kiss SWMBO then tell her she been kissed on a Grand Scale
Works every time !,,,,,,,,,,might
