Not all Interstates *ought* to be tagged as motorways. A case in point
is Interstate 93 in Franconia Notch, New Hampshire, which *ought*
to be a trunk (it's a two-lane road with a centre guard rail that was added
long after the initial construction.)

Many motorways are not Interstates. The local law where I live doesn't
special-case Interstates, but rather uses phrasing like 'multi-lane
grade-separated controlled-access highways'.

But that said, if a piece of legislation says, 'Interstate', then it means
specifically 'Interstate', whether motorway or not, and not other motorways.
