In the Republic of Ireland, such signs appear normally on national routes and upgraded regional roads. Officially known as "route confirmation signs", there are two variants; the smaller (featuring just the road number) is common after minor junctions, and a full route confirmation sign will feature the route number and several destinations and the distances to them (with distances not directly reached by that particular route number in brackets). Euroroute numbers have begun to appear on these signs but are not yet commonplace. On motorways and high quality dual carriageways, they appear after every junction (except on the M50, on which they are not typically used). On other national roads they appear when leaving built-up areas. Some regional roads feature route confirmation signs, but they are not common on these roads.
