Do you mean for the purposes of licensing, Redhand or for committing an offence for driving overladen?
Licensing Because plod has no way of knowing what a car and trailer weighs (without a trip to weighbridge) the rules apply to the MAM of the trailer regardless of whether it's empty or loaded. you could have a titanium/carbon fibre trailer weighing 300kg If it's plated as having a mam of 3500kg or if the MAM of the trailer is higher than the weight you can tow without B+E then you can't tow it..
