A motorway would be two or more carriageways, limited access (ie, no driveways and no at-grade intersections). A trunk road would either be a dual carriageway with surface intersections with cross streets, and limited or no direct driveway access (eg, OK 3 in Oklahoma County, aka Northwest Expressway). Alternatively, a single carriageway that is limited access, ie, no intersections, no driveways, only ramps (eg, Chickasaw Turnpike in Oklahoma). Essentially, almost a motorway but not quite there.
