for all practical purposes, a trunk is a motorway-wannabe, but with 
grade level crossings of
some sort, either with stop signs for the lesser roads, or traffic 
lights. you generally won't
see driveways or businesses directly on trunks, there will often be 
frontage roads for that.

the portion of US 41 you point out is a bit schzoid, mostly grade 
separated but with a scattering
of grade level crossings. the points with grade level crossings should 
certainly be trunk.
