[talk-au] When is a road, not a road?

[Warren]

I suspect the answer to this question  is simple.

Following Sam Wilson's post about the data sources available for Western 
Australian Roads, and using Sam's approach I have begun adding and 
checking road names in WA.  In  the area that I am currently working 
there are a number of named "roads" on  OSM (usually Highway: 
unclassified), that do not appear on the Main roads data.

If a road is not on the Main roads database does it automatically become 
a named track (Highway: Track)    ?
