every point where a motor vehicle may duly pass from a length of road on which a speed limit is in force to a length of road on which a speed limit is not in force:
Provided that where the length of road on which the speed limit is not in force is a dual carriageway road one sign shall be erected on the left or near side of the road and one sign shall be erected on the central reservation instead of on the right or off side of the road.
8. Signs shown in diagram 5 in the First Schedule shall be erected in accordance with the provisions of the next succeeding paragraph along a length of road on which there are one or more street lamps and on which no speed limit is in force.
9. A sign mentioned in the last preceding paragraph shall be erected on each lamp-post along any length of road mentioned in that paragraph so as to be clearly visible to the drivers of motor vehicles using the road, but if any lamp is mounted otherwise than on a post or if any existing lamp-post is not available or cannot conveniently be used for the purpose of erecting the sign upon it such sign shall be erected on a post to be specially placed for the purpose by the side of the road as close to each lamp as is consistent with the visibility of the sign to the drivers of motor vehicles using the road:
Provided that where on such a length of road—
(a) there is a lamp which is placed more than two hundred yards from the nearest other lamp on that road; or
(b) on one side of the road there are more than three lamps without there being any lamp on the other side of the road between the first and last of those lamps; or
(c) there are not more than three lamps which are placed two hundred yards or less apart;
two such signs facing in opposite directions shall be erected on each lamp-post on which is mounted each of such lamps or on a post close to each of such lamps, as the case may require.
10. Where a sign shown in any of the diagrams in the First Schedule or the Second Schedule is mounted on or attached to a post specially provided for that purpose, such post shall be painted in alternate black and white bands, each band being not less than eleven inches nor more than thirteen inches in width.
11. Nothing in these Directions shall be taken to limit the power of the Minister by any special Direction to dispense with, add to or modify any of the requirements of these Directions in their application to any particular case.
Given under the Official Seal of the Minister of Transport and Civil Aviation this twenty-first day of February, 1957.
