Protocol nopens de verkeerstekens

The contracting Parties to this Protocol accept the system of road signalling described herein and undertake to introduce it as soon as possible. For this purpose they will erect the signs set out in this Protocol as and when new signs are put up or those now in existence are renewed. Signs which do not conform to the system provided in this Protocol shall be completely replaced within a period not exceeding ten years from the date of the coming into force of this Protocol in respect of each of the Contracting Parties.

The Contracting Parties undertake, as soon as this Protocol comes into force, to replace signs which, although they have the distinguishing features of a sign belonging to the system provided in this Protocol, are used with a different meaning from the one attaching to that sign in this system.

The international system of roadside traffic signs shall comprise three classes of signs namely:
(a) Danger signs;
(b) Signs giving definite instructions subdivided into: (i) Prohibitory signs,
(ii) Mandatory signs;
(i) Prohibitory signs,
(ii) Mandatory signs;
(c) Informative signs subdivided into: (i) Indication signs,
(ii) Advance direction signs and direction signs,
(iii) Place and route identification signs.
(i) Indication signs,
(ii) Advance direction signs and direction signs,
(iii) Place and route identification signs.

There shall be a distinctive shape for each class of sign.

1. The symbols as indicated on the signs shown in the tables appended to this Protocol shall be accepted bij the Contracting Parties as the fundamental basis of their roadside traffic signs. As a rule they shall appear within the signplate.
2. Where Contracting Parties consider it necessary to modify the symbols, these modifications shall be such as not to alter the essential character of the symbols.
3. For the purpose of facilitating the interpretation of the signs additional information may be given on a rectangular plate below the sign.
4. Where an inscription is used within or below a sign, it shall be in the national language or languages, and if so desired in one of the official languages of the United Nations. The provisions of this paragraph shall not apply to the inscription “stop” referred to in article 33, paragraph 2.
5. New signs created by Contracting Parties in accordance with the provisions of paragraph 1 of article 17 of the Convention on Road Traffic opened for signature at Geneva on 19 September 1949, shall be communicated to the Secretary-General of the United Nations, who shall notify all Contracting Parties.

1. The colours used on the signs, symbols and inscriptions shall be those prescribed in this Protocol, unless exceptional conditions make them impracticable.
2. Where the colours to be used are optional, each country shall employ the same colours for any one class of signs used under the same conditions.
3. The reverse side of signs shall be of a neutral colour except in the case of the signs III, C.Ia, b and symbol II, A. 15 when affixed to he reverse side of sign II, A. 14.

The use of lighting or of reflecting materials or devices is recommended at least for danger signs and signs giving definite instructions where such use improves the visibility of roadside traffic signs at night time; but they should not dazzle road users or obscure the legibility of the symbol or the inscription.

1. The dimensions of sign plates shall be such that the sign can be easily seen from a distance and easily understood near at hand.
2. The dimensions of various signs shall be standardised in each country so as to ensure the maximum uniformity. In general, two sizes shall be used for each type, namely, a standard size and a reduced size for use where conditions do not permit or the safety of road users does not require the erection of the standard sizes. In exceptional circumstances, a special small type sign may be used inside built up areas or for repeating the main sign.

1. Outside built-up areas, the centre line of the signs shall be not more than 2 m from the nearside edge of the carriageway unless special circumstances render this impracticable.
2. In built-up areas and mountainous country, the distance between the edge of the sign nearest the carriageway and a vertical line drawn from the edge of the carriageway shall be not less than 0.50 m. In exceptional cases, however, this distance may be reduced.

1. In this Protocol the height of signs above the ground shall mean the height of the lower edge of the signs from the level of the road.
2. So far as possible a uniform height shall be observed over the same route.

1. The danger signs shall be in the shape of an equilateral triangel with one point upwards except in the case of sign “Priority road ahead” (I, 22) which shall have a point downwards.
2. These signs shall have a red border with white or light yellow ground. Symbols shall be black or dark.
3. For signs of the standard size, the length of each side of the triangle shall be not less than 0.90 m and for the reduced size, not less than 0.60 m.
4. The signs shall be placed on the side of the road appropriate to the direction of the traffic concerned and facing that traffic. They may be repeated on the other side of the road.
5. Unless otherwise provided hereafter in this Protocol, the signs shall be placed at not less than 150 m and not more than 250 m from the hazard unless this is impracticable on account of local conditions. In such exceptional cases the sign shall be erected at less than 150 m, but as far as possible from the hazard and special provisions shall be made.
6. The height of signs shall be not more than 2.20 m and, outside built-up areas, not less than 0.60 m.
7. The signs shall be placed in such a way that they cannot be obscured nor be a hindrance to pedestrians.

The sign “Uneven Road” (I, 1) shall be used wherever the competent authorities deem it necessary, as the approach sign to sections of the road in which the road is uneven, to a gutter or drain crossing the road, or to a humpback or hump bridge.

1. The sign ”Dangerous bend” of ”Dangerous bends” (I, 2) shall be used only as the approach sign for a bend or bends, which are dangerous owing to their physical characteristics or to reduced visibility.
2. Each Contracting Party may elect to substitute for the above sign, signs giving a clearer indication of the bend or bends. Such substitution shall apply throughout the territory of the Contracting Party concerned. These alternative signs are:
I, 3 — right bend
I, 4 — left bend
I, 5 — double bend, the first to the right
I, 6 — double bend, the first to the left.

1. The sign “Road intersection” (I, 7) shall be used, wherever the competent authorities deem it necessary, as the approach sign for a fork, crossroads or road junction. In built-up areas this sign shall only be used in exceptional cases.
2. When there is a roundabout at the crossroads to be indicated, the sign I, 7bis shown below may be used instead of sign I, 7; where the left-hand rule of the road is observed, the arrows on the sign shall be reversed.

1. The sign “Level-Crossing with Gates” (I, 8) shall be used as the approach sign for every level-crossing with gates and for every level-crossing equipped with staggered half-gates on either side of the railway track.
2. The sign “Level-Crossing without Gates” (I, 9) shall be used as the approach sign for every level-crossing without either gates or half-gates.
3. On roads with a large volume of motor traffic during the night, the signs referred to in paragraphs 1 and 2 of this article shall be adequately illuminated or provided with reflectors or reflecting material.
4. At level-crossings equipped with gates or half-gates, the extension of such gates or half-gates across the road shall mean that no road-user may pass; the movement of gates or half-gates shall have the same meaning.
5. The gates and half-gates of level-crossings shall be painted in stripes of red and white or red and light yellow. Alternatively, the gates may be painted white or light yellow with a large central red disc. In order to make gates more visible at night they shall either be provided with red lights or red reflectors or red reflecting material or be illuminated by a floodlight whenever they are not fully open.
6. At all level-crossings without either gates or half-gates there shall be placed, in the immediate vicinity of the railway line, a sign in the form of a St. Andrew's cross (I, 10 and I, 11) or a rectangular signplate, on which this symbol is displayed against a neutral background. The St. Andrew's cross or in any case its lower arms, may be double if there are two tracks or more. It shall be painted in red and white or in red and light yellow.
7. In the case of level-crossings situated on local railways, on connecting-lines to factory sidings or on parts of railway lines assimilable to such connecting lines, especially in the case of roads of minor local traffic importance or where a level-crossing is coincident with a road intersection, each Contracting Party may:
outside built-up areas, make certain simplifications in or exceptions to the system laid down in paragraphs 1, 2, 3, 5 and 6 of this article;
in built-up areas, apply whatever regulations it deems most appropriate in place of the provisions of paragraphs 1, 2, 3, 5 and 6 of this article.

The sign ”Intersection with a non-priority road” (I, 20) shall be used wherever the competent authorities deem it necessary on a priority or a major road as an approach sign to an intersection with a non-priority road, in the territory of any Contracting Party where the use of such a sign corresponds to traffic rules.

1. The sign ”Other danger” (I, 21) shall be used, wherever the competent authorities deem it necessary, as the approach sign for a danger other than those indicated in articles 12 to 24 of this Protocol.
2. However, an inscription in black or dark colour defining the danger, such as limited headroom or width, ferry or falling rocks, may be placed within the sign in substitution for the symbol.
3. This sign shall always contain the symbol or an inscription or both.
4. An additional rectangular plate bearing an inscription or a symbol in current use in the territory of the Contracting Party may be placed underneath the sign.

Where atmospheric conditions do not permit the use of the full sign, a hollow red triangle may be used to indicate the different dangers referred to in articles 12 to 25. A rectangular plate shall always be placed below the triangle on which the appropriate symbol or inscription or both of them shall be given to indicate the danger.

(f) The sign ”End of speed-limit” (II, A. 15) (white or light yellow ground with an oblique black or dark coloured bar) shall be used to indicate the point at which the effect of the sign ”Speed-limit” ceases; it may be affixed to the reverse side of sign II, A. 14 even though, as a result, it would not be placed on the side of the road appropriate to the direction of the traffic.

1. The sign “Stop at intersection” shall be used to indicate that a driver shall stop before entering another road and shall give way to vehicles moving along that road.
2. This sign shall consist of a red triangle with the point downwards inscribed within a red circle. The triangle may have the word ”Stop” as shown in the diagram II, A. 16.
3. The diameter of this sign shall be at least 0.90 m for the sign of standard size and at least 0.60 m. for the reduced size.
4. This sign shall be placed at roads without priority, at a suitable distance from the intersection, up to 50 m in open country and up to 25 m in built-up areas.
It is recommended that there should also be placed on this road a suitable position sign, mark or line, as near to the intersection as practicable.

Diagrams I, 8a, I, 9a, I, 8/9b and I, 8/9c are examples of these plates.

1. If a signalling system is installed at a level-crossing to give warning of the approach of a train or of the imminent closing of the gates or half-gates, it shall consist either
(a) subject to the provisions of paragraph 4 of this article, of a flashing red light or two red lights flashing alternately and placed on the same post; such light or lights being accompanied or not being accompanied by a sound signal; or
(b) of a simple sound signal.
2. (a) All level-crossings equipped with gates or half-gates operated from a box from which the gates are not visible shall be equipped with the signalling system described in paragraph I(a) or in paragraph l(b) above;
(b) All level-crossings equipped with gates or half-gates operated automatically by the approach of trains shall be equipped with the signalling system described in paragraph l(a) above.
3. The signal provided for in paragraph 1 of this article means that no road-user may pass.
4. Exceptionally, on roads where the level-crossing is near an intersection equipped with the traffic light signals described in article 53 of this Protocol, the signalling referred to in paragraph 1 of the present article may be replaced either by the three-colour light system described in the aforesaid article 53 or by the amber and red lights only of that system; the amber and red lights shall then have for all road-users the meaning indicated in article 53 for vehicular traffic. In the event of such replacement, the approach sign provided for by paragraph 1 or paragraph 2 of article 15 may be dispensed with if, by reason of local conditions, it would be difficult to affix it in such a way that it would be sufficiently visible.
5. At every level-crossing equipped with gates or half-gates the operation of which is controlled automatically by the approach of a train or is controlled from an operating box from which the gates or half-gates are not visible, the closing movement of the gates or halfgates shall be such that road-users approaching the crossing or already on it when the signalling device comes into operation shall have time to stop before reaching the crossing, or to clear it.

At all level-crossings equipped with gates or half-gates, the gates or half-gates shall be kept in operation during the whole period when train services are in operation. Should a level-crossing with gates or half-gates be permanently reclassified as a level-crossing without gates or half-gates, the gates or half-gates shall be removed to avoid any misunderstanding on the part of the users of the road.

The devices signalling the approach of trains prescribed in article 47, paragraph l(a) of this Protocol shall be placed in the immediate vicinity of the railway and, if a sign in the form of a Saint Andrew's cross is used, wherever possible on the same post as that sign. Where signalling is automatic, appropriate measures shall be taken to guard against any defect in the working of a signal and to ensure that the signal cannot be misinterpreted if it fails to work or works incorrectly.

Level-crossings shall not be without either gates or half-gates and signalling of the approach of trains unless the railway line on both sides of the level-crossing is clearly visible to road-users, having regard, in particular, to the speed of the trains, so that the driver of a vehicle approaching the railway from either side may have time to stop before entering the level-crossing when a train is in sight and road-users who have already entered the crossing when a train appears have time to clear the crossing.

Traffic police shall be so equipped and stationed as to be visible to alle road users.

1. Signals to be made by traffic police shall conform to one of the two following systems:
Signal A — to indicate ”Stop” to the vehicles approaching the officer from the front: arm raised vertically, palm of the hand to the front.
Signal C — to indicate ”Stop” to the vehicles approaching the officer from the rear: arm extended horizontally to the side of the road to which the traffic concerned is keeping, palm of the hand to the front.
Signals A and C may be used simultaneously.
Signal B — to indicate ”Stop” to the vehicles approaching the officer from the front: arm extended horizontally to the side of the road to which the traffic concerned is keeping, palm of the hand to the front.
Signal C — to indicate ”Stop” to the vehiclues approaching the officer from the rear: arm extended horizontally to the side of the road to which the traffic concerned is keeping: palm of the hand to the front.
Signals B and C may be used simultaneously.
2. Under both systems, a beckoning gesture with the hand may be made to call vehicles forward.

1. The lights of the traffic light signals shall be given the following meaning:
(a) In a three-coloured system: Red indicates that vehicular traffic must not pass the signal; Green indicates that vehicular traffic may pass the signal; When amber is used after the green signal, it shall be taken as prohibiting vehicular traffic from proceeding beyond the signal unless the vehicle is so close to the signal when the amber signal first appears that it cannot safely be stopped before passing the signal; — When amber is used in conjunction with or after the red signal, it indicates an impending change in the indications of the signal and shall not be taken as permitting verhicular traffic to proceed.
(b) In the two-colour system: Red indicates that vehicular traffic must not pass the signal; Green indicates that vehicular traffic may pass the signal; The combination of green and red shall have the same meaning as amber after green in the three-colour system.
2. When a single amber intermittent light is used, it shall indicate “caution”.
3. The lights shall be placed one above the other. As a rule the red light shall be placed at the top and the green light at the bottom. Where an amber light is used, it shall be placed between the red and the green lights.
4. When traffic light signals are placed at the side of the carriageway, the height of the lower edge of the lowest light above the carriageway shall normally be not less than 2 m and not more than 3.50 m; where possible, every light signal should be repeated on the opposite side of the intersection. When they are suspended over the carriageway, the height of the lower edge of the lowest light above the carriageway shall be not less than 4.50 m.

1. Where a carriageway outside a built-up area has more than two lanes, these shall as a rule be made clearly distinguishable.
2. Where a three-lane carriageway outside a built-up area passes through sections where the visibility is not sufficient, or at other danger points, the total width of the carriageway shall be divided only into two lanes.
3. Where a carriageway has two lanes in any section where the visibility is not sufficient and at other danger points, the lanes should be clearly distinguishable.
4. The marking of lanes as provided for under paragraphs 2 and 3 of this article indicates that under normal traffic conditions no vehicle shall deviate from the lane reserved for traffic proceeding in its direction.

1. Where the edges of the carriageway are defined by means of lights or reflecting devices, two different colours may be used for such lights or devices.
