highways by all or any specified classes of vehicles should incorporate a red disc or ring and these symbols should be used only where appropriate statutory powers have been exercised. (Paragraph 86.)
(27) Design of Mandatory Signs.
(a) Signs which indicate that in conformity with a Statutory Order or Regulation traffic must proceed in a specified direction, should be surmounted by a red ring.
(b) The symbol of the inverted red triangle within a red ring should not be used on any signs other than the “Slow” and “Halt” signs erected on the approach to a major road.
(c) “Stop ” signs should be displayed only during such time as the
injunction is in force. (Paragraph 101.)
(28) Through Direction Signs.—A satisfactory system of direction signposting should provide the road user with the following information:
(i) Clear information in good time as to his proper route at places where he might otherwise be in doubt. }
(ii) Confirmation from time to time that he has not deviated from his route.
(iii) Indication of the names of the places through which he is passing.
(iv) Information as to mileages.
Any satisfactory system of direction signs must be based on the use of route numbers, and the existing system should be continued. (Paragraph 106.)
(29) Route Number System.—The through direction signposting system should be made more widely known, and information about the system should be given greater publicity. Alterations of route numbers should be readily available to the public. (Paragraph 107.)
(30) Approach Direction Signs—The route number should remain the more important feature on the panels and not more than one place name should appear on one panel. The letters and figures for the route number should not be less than 4 in. or more than 44 in. high. The letters in the place name should be not less than 2 in. or not more than 3 in. high, instead of not more than 2 in. high as at present. (Paragraph 110.)
(31) Approach Sign Where Space is Restricted—A new form of approach direction sign is recommended for use where space restrictions prevent the use of signs of the existing form. (Paragraph 120.)
(32) Colour Surround to Approach Direction Signs in Towns.—In order to improve conspicuity, the black and white panels on approach direction signs in towns should be mounted on a yellow background or surround.
Recommendations are made for the definition of the areas in which this colour should be used. (Paragraph 121.)
(33) Local Direction Signposting—A new approach direction sign for local signposting is recommended. In towns, the background or surround of this sign should be “traffic blue ”’ in order to improve conspicuity and to emphasise the difference from “through” signs. (Paragraph 124.)
(34) Display of Street Names and Street Numbers—Uniformity of practice in the display of street name plates and street numbers is important. We consider that the results achieved by the exercise of existing statutory powers are unsatisfactory, and recommend that the Minister’s attention should be specifically directed to the desirability of a review
