1. Because of the special danger presented by level-crossings, the Contracting Parties undertake:
(a) To have one of the danger warning signs bearing one of the symbols A, 25; A, 26 or A, 27 placed in advance of all level-crossings; however, no sign needs to be set up (i) In special cases which may arise in built-up areas;

(i) In special cases which may arise in built-up areas;
(ii) On earth-tracks (dirt roads) and paths where power-driven vehicular traffic is exceptional;
(b) To have all level-crossings equipped with gates or half-gates or with a signal giving warning of the approach of trains, unless road-users can see the railway line on both sides of the level-crossing for such a distance that, allowing for the maximum speed of the trains, the driver of a road vehicle approaching the railway line from either side has time to stop before proceeding on the level-crossing if a train is in sight, and in addition that road-users who are already on the crossing when a train appears have time to reach the other side; however, it shall be open to the Contracting Parties to derogate from the provisions of this sub-paragraph at level-crossings where trains travel relatively slowly or power-driven vehicular traffic on the road is light;
(c) To have every level-crossing having gates or half-gates operated from a position from which such gates or half-gates cannot be seen equipped with one of the systems for signalling the approach of trains referred to in Article 33, paragraph 1, of this Convention;
(d) To have every level-crossing having gates or half-gates operated automatically by the approach of trains equipped with one of the systems for signalling the approach of trains referred to in Article 33, paragraph 1, of this Convention;
(e) In order to make gates and half-gates more visible, to have them equipped with reflecting material or reflecting devices and, if need be, to illuminate them at night; in addition, on roads where is heavy motor traffic at night, to equip the danger warning signs installed in advance of the level-crossing with reflecting material or reflecting devices and, if need be, to illuminate them at night;
(f) Wherever possible, near level-crossings equipped with halfgates to have a longitudinal marking placed in the middle of the carriageway prohibiting vehicles which approach the level-crossing from encroaching on the half of the carriageway reserved for traffic in the opposite direction or even to install directional islands separating the two opposed streams of traffic.
2. The provisions of this Article shall not apply in the cases referred to in the last sentence of Article 35, paragraph 2, of this Convention.
