 (ii) In direction signs of the fingerpost type the badge should be on the arm in immediate proximity to its junction with the post.

(iii) In rectangular signs, such as approach signs, advance direction signs and village name-plates, where, owing to the varying lettering, there is space available, the badge may be placed in one of the four corners of the sign, but thenearest edge of the badge should not be more than 4 in. from the edge of the plate.

(iv) In the case of all signs other than these referred to in (i) and (ii) the badge should be fixed either above or below the sign, subject to the provisions of (iii) above, and should be contained in a circle of an area not exceeding 7½ per cent of the area of the plate on which it is fixed. The circle containing the badge may be supported by solid attachments to the plate, such attachments being contained within the tangent drawn to the circle from the upper or lower corners of the plate.

(v) In the case of the signs referred to in (i) and (ii) above, not more than 7½ in. in length of the sign or arm should be appropriated to the display of the badge.

APPENDIX VI (Diagrams 1 to 128)

Notes:

1. Except where otherwise provided in note 2 below, or in notes on the diagrams, all letters, numbers, symbols and borders on signs are black on a white ground.

2. In towns as defined in paragraph 121, the background colour, outside the route number panels on the signs shown in diagrams 78 to 92 inclusive, should be yellow; the background colour on the sign shown in diagram 102 should be traffic blue.

3. The overall dimensions given for the direction signs shown in diagrams 76 to 103 inclusive, are approximate only and are based on the minimum sizes of letters. They will require to be varied according to the size and number of letters in the route numbers and place names.

4. In the approach direction signs shown in diagrams 78 to 82 inclusive, 84 to go inclusive, and 92, the letters and numerals in the route numbers may not be less than 4 in. or more than 4½ in. high. The letters in the place names may not he less than 2 in. or more than 3 in. high.

In paragraphs 24 and 26 of the Report it is recommended that on unlighted roads where direct illumination of warning, prohibitory or mandatory: signs is not practicable, reflecting lenses should be fitted on these signs. Letters not less than 3 in. high can be fitted with reflecting lenses (e.g. on 3 in. letters, with ⅜ in. diam. lenses at ¾ in. centres) to give reasonable legibility at night when viewed in the light of vehicle headlamps. It has been thought sufficient to show in the diagrams the recommended arrangements of reflecting lenses only on those warning signs in which the message of the sign 18 conveyed by a symbol.
