your right Dave it is illegal to tow a trailer with people riding in the back with a motor vehicle ,
Thing about carnival float parades ect is there is usually strict rules to be adhered to from the local council which grant permission to tempory close the road off whilst its in procession and there is usually some sort of police presence en route with a very slow speed as one of the rules ,
i have towed publicity lifeboats usually old d classes in various offical parades for the last 20 years or so all over yorkshire often with people sitting on the boat ,
though the lifeboat code of practice is only to have a max of 3 people all must be holding on and all should be sat facing forwards with a max speed of 3 mph (unless its a shout or a boat thats in operational service).
think the only people that may still be allowed to ride in the backs of trailers are those classed as showmans such as steam traction engines or fairground types though they used to be limited to 20 mph.
