There is 2 « independant » things in the debate : 1) trunk definition - what is a trunk, a motorway-like road - based on physical characteristics- or a super-primary road - based on the importance ? 2) wordwilde trunk definition ? - should we have the same definition all over the world of what is highway= trunk ? (value that are country-dependant are not that common, aren’t they ?)
