Uncontrolled tramway crossing or tram line

This triangular sign showing a tram warns of an uncontrolled tram line that crosses the carriageway or reduces the space available to traffic, inside or outside a built-up area. Reduce speed, watch for trams and do not obstruct them. You may drive on the rails only if this does not impede a tram. Specific rules govern passing a tram, including whether passengers have a pedestrian refuge or boarding island. The sign does not warn of trolleybuses, a railway level crossing or a bus parking area.
