Though Openstreetmap strives for global definitions, local variations
also exist. For example, in French Openstreetmap "trunk" must be a
dual-carriage way - that rule does not exist in the rest of the
Openstreetmap world. But divergence carries the cost of increased
complexity - tread lightly there: not all Openstreetmap communities have
sufficient power to deal with it.
The ref=* tag might help you: the national highway numbering schemes
reflect the national classification - so it might be a good source of
"official" truth to carry the national road agency's vision regardless
of what the way actually is.
