When, exceptionally, a traffic light consists of an illuminated white bar on a round black background, its signals apply only to trams and regular-service buses, unless there is a lane reserved for buses, or for buses, taxis and other vehicles; in that case, they apply only to the vehicles using that lane. These traffic lights mean the following: (1) an illuminated horizontal white bar prohibits passing in the same conditions as a steady red light; (2) an illuminated vertical white bar allows you to go straight on; (3) an illuminated white bar slanting to the left or to the right indicates that you may pass to turn left or right respectively; (4) a vertical or slanting white bar lit intermittently indicates that these vehicles must stop in the same conditions as for a steady amber light.
