The american concept of freeways is unambiguous, though we do have some oddities with expressways, which we map as trunks. No/few driveways, usually surface intersections but could also have motorway-style ramps at higher traffic junctions, or (far more rarely) a controlled access single carriageway (it's a motorway, but instead of dual carriageway, it's typically a two lane road at the top of the ramps) would qualify as a trunk, as well.
