In this situation, does the tram driver have the right of passage over the tram driving on the transverse track?

The situation shown is a junction of tramways of equal priority, at which there are no signs or signals regulating priority. In such a case, the tram driver, like other drivers, must observe the priority to the right rule. This means they must give way to rail vehicles approaching from their right, i.e., in this case, those travelling on the intersecting tramway.
