Its tagged as a "track" which in OSM terminology means its not necessarily a road, but should be suitable for tractors etc to use. Can you have a look at the distinction at https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrack#highway.3Dtrack_versus_other_classes_of_highway.3D.2A and see whether you think it should be classified differently -- or alternatively, tell us the width and surface so we can update appropriately.
