I would say the rule ought to be that it should be mapped in accordance
with local laws and
regulations as to the nature of the link.  If that cannot be determined,
then the mapper has to use
best guest based on context, topology, shape, speed limit and other
signage.  For UK motorways
the regulations say motorway access roads are classed as motorways and the
road signage
confirms it.  That is not necessarily the case for links other than to
motorways, and possibly not
even for all of those (there are always exceptions).

I suspect the wiki entry was written in days of yore when a question arose
about motorway
access roads and it became enshrined as a general rule for all link roads
of all types in all
countries.  Whatever the origin, I think it is time to amend it to
something more sensible.
