Agreed.  To me trunk means:

  paved
  divided
  very few at grade intersections or driveways (one every few miles is ok)

basically "sort of like a motorway, but not quite".

primary already means "this is a very main road".

There are plenty of primary roads with 65 MPH speed limits out there.
If they aren't divided or have more-than-occasional at-grade
intersections or driveways, that's the right classification.

I don't think a road that isn't physically trunk should get tagged as
such just because it is the most important road (or the only road).
