Should one use highway tag specific to country

Respected All,

I would like to have the suggestions from the community that Roads classification tags should be country specific or a number of lanes of the roads OR the type of cities/places it is connecting. I am particularly concerned with the Status of Indian Roads. What is followed for other countries.

Thanks

It’s country specific, see http://wiki.openstreetmap.org/wiki/Highway:International_equivalence
It has a link to a page specific for India I see.
