Convention on Road Sings and Signals

Annex 2
ROAD MARKINGS
Chapter III
Transverse markings
A. General
29. Because of the angle at which the driver sees markings on the carriageway, transverse markings shall be wider than longitudinal markings.
B. Stop lines
30. The minimum width of a stop line shall be 0.20 m and the maximum 0.60 m. A width of 0.30 m is recommended.
31. When used in conjunction with a STOP sign, the stop line should be placed in such a position that a driver who stops immediately behind the line has the clearest possible view of the traffic on the other arms of the intersection consistent with the requirements of other vehicular and pedestrian traffic.
32. Stop lines may be supplemented by longitudinal lines (diagrams 18 and 19). They may also be supplemented by the word "STOP" inscribed on the carriageway as shown in the examples given in diagrams 20 and 21. The distance between the top of the letters of the word "STOP" and the stop line should be between 2 m and 25 m.
C. Lines indicating points at which drivers must give way
33. The minimum width of these lines should be 0.20 m and the maximum width 0.60 m; if there are two lines, the distance between them should be at least 0.30 m. The line may be replaced by triangles marked side by side on the ground with their vertices pointing towards the driver who is required to give way. The bases of these triangles should measure at least 0.40 m but not more than 0.60 m and their height should be at least 0.60 m but not more than 0.70 m.
34. Transverse marking(s) should be placed in the same positions as the stop lines referred to in paragraph 31 of this Annex.
35. The marking(s) referred to in paragraph 34 above may be supplemented by a triangle drawn on the carriageway as shown in the example given in diagram 22. The distance between the base of the triangle and the transverse marking should be between 2 m and 25 m. The base of the triangle shall be at least 1 m; its height shall be three times its base.
36. This transverse marking may be supplemented by longitudinal lines.
D. Pedestrian crossings
37. The space between the stripes marking a pedestrian crossing should be at least equal to the width of the stripes and not more than twice that width: the width of a space and a stripe together should be between 1 m and 1.40 m. The minimum width recommended for pedestrian crossings is 2.5 m on roads on which the speed limit is 60 km/h, and 4 m on roads in which the speed limit is higher or there is no speed limit.
E. Cyclist crossings
38. Cyclist crossings should be indicated by two broken lines. The broken line should preferably be made up of squares (0.40-0.60) x (0.40-0.60) m. The distance between the squares should be 0.40-0.60 m. The width of the crossings should be not less than 1.80 m. Studs and buttons are not recommended.
