The sign indicates that the number of lanes is increasing. The brand is adapted to the conditions on site. Symbols for vehicle types, road numbers or physical demarcations between opposite lanes may be inserted in the mark. The mark is also used as a preparatory information that the number of lanes is increasing. The distance is then indicated on an additional board. In the event of temporary traffic diversion, the mark may be made on an orange background. Otherwise, deviation from color must not occur.
