Artikel 46

Wherever the competent authorities deem it necessary, a vertical plate bearing three red oblique bars on a white or yellow ground may be placed below a sign I, 8 or I, 9, provided that plates of identical form and bearing respectively two red oblique bars and one red oblique bar on a white or yellow ground are placed as independent signs at about two-thirds and one-third of the distance between that sign and the railway line. Diagrams I, 8a, I, 9a, I, 8/9b and I, 8/9c are examples of these plates.
