You should use the link type which reflects the set of rules that apply to that road. If the link is under motorway rules, use highway=motorway\_link; `highway=motorway_link`; if it's under trunk road rules (for your country) use highway=trunk\_link, `highway=trunk_link`, and so on. This is where the meaning in *_link `*_link` highway types comes from. If there's no explicit designation for a link road, you can deduce the rules in place from clues like where the speed limit changes, any roadside markings, or any other roadsigns (such as No Stopping) signs. It may not always be the designation for the higher of the two roads it connects. The ref=* `ref=*` should be omitted unless the link road itself has a route reference.
