There will always bee national differences.  In Scandinavia we do not 
keep the national number on the A and B-class roads, while in GB, they 
to not mark them at all, nor do they have ferries to link them together 
where there is no bridge or tunnel.

As it goes for tertiary, it's difficult to say from one country to an 
other what is the correct tag. The most important is the hiracy, and get 
in agreement of the whats what in each country.

I would say that
"tertiary is a slightly more important road than unclassified and 
residential (A subdivision main road; A industrial park main road; a 
rural man road near a larger road)"

I drove on a road yesterday which you call a track. The traffic on this 
"track" flowed at speeds between 80-90kph.

The road in question is a A-class road. ref=E34.

So you want that E6, E34, E16 (A-class roads) and E134 (B-class road) to 
be tagged as track????

Tag by importance, not how someone somewhere wants your road quality to bee.

note: all road-class is after the definition of the UN-body that defines 
the E-roads....
