So an empty truck will have to sit behind a fully laden truck in theory from one end of the m6 to the other even up hills where the laden truck will have to change down gears and the empty truck can stay in top gear?
Yeah, why not. 56mph is 56mph.
I think the point Retribution forgot to mention is that heavily laden lorries will slow down considerably on inclines, while light or empty ones do not have to. Then you have Tesco lorries with limiters set at 50mph.. So sitting behind slower moving lorries becomes a bit silly when it is perfectly safe to overtake.
