While checking the rendering of highway link roads (eg motorway_link, primary_link, tertiary_link), I noticed that in some cases these tags are used when a road splits in a Y-junction, for example before a traffic circle / roundabout. In some areas these are the most common forms of _link for less major roads, eg secondary_link and tertiary_link.
On the wiki there was some debate about whether it was correct to tag a Y-junction as leading into link roads, or if these should only be used for slip lanes and on-ramps which merge off of or onto the through-lanes of another road: https://wiki.openstreetmap.org/wiki/Talk:Highway_link Also see https://wiki.openstreetmap.org/wiki/Highway_link which is marked with a banner that "This article or section contains questioned, contended or controversial information."
