CONVENTION ON ROAD SIGNS AND SIGNALS
The Contracting Parties, recognizing that international uniformity of road signs, signals and symbols and of road markings is necessary in order to facilitate international road traffic and to increase road safety, have agreed upon the following provisions:
Chapter III
TRAFFIC LIGHT SIGNALS
ARTICLE 24
Signals for pedestrians only
1. The only lights which may be used as light signals for pedestrians only are the following, which shall have the meanings here assigned to them:
(a) Non-flashing lights:
(i) A green light shall mean that pedestrians may cross;
(ii) An amber light shall mean that pedestrians may not cross, but that those already on the carriageway may continue to the other side;
(iii) A red light shall mean that pedestrians may not enter the carriageway;
(b) Flashing lights: a flashing green light shall mean that the period during which pedestrians may cross the carriageway is about to end and the red light is about to appear.
2. Light signals for pedestrians shall preferably be of the two-colour system, comprising two lights, red and green respectively; however, they may be of the three-colour system, comprising three lights, red, amber and green respectively. Two lights shall never be shown simultaneously.
3. The lights shall be arranged vertically, with the red light always at the top and the green light always at the bottom. The red light shall preferably be in the form of a standing pedestrian or of standing pedestrians and the green light in the form of a walking pedestrian or of walking pedestrians.
4. Light signals for pedestrians shall be so designed and arranged as to exclude any possibility of their being mistaken by drivers for light signals for vehicular traffic.
5. Light signals for pedestrians may be supplemented by audible or tactile signals at pedestrian crossings to facilitate crossings of the carriageway by blind pedestrians.
