Regulation 31 Permitted variants of green arrow light signals
A lens or lenses of the size and colour shown in either diagram 3001 or 3001.1 which, when illuminated, shows a green arrow
may be substituted for the lens showing the green light in the light signals referred to in regulation 30(2) using any of the methods shown in diagram 3003, 3005, 3006, 3011.1 or 3011.2; or
may be affixed to the light signals referred to in regulation 30(2) or to those signals as altered in accordance with sub-paragraph (a) using any of the methods shown in diagram 3000.4, 3000.6, 3002, 3004, 3005, 3006, 3007, 3008, 3009.1, 3011.1 or 3011.2.
The direction of the arrow prescribed as the permitted variant of diagram 3000.3 and shown in diagram 3000.4 may be varied so that the head of the arrow points to any position on the 90° arc shown in diagram 3002 or 3004.
The direction of the arrow prescribed as the permitted variant of diagrams 3000 and 3000.5 and shown in diagram 3000.6 may be varied so that the head of the arrow points to any position on the 180° arc shown in diagram 3003 or 3009.1.
The direction of any arrow prescribed as a permitted variant of diagrams 3000.3 and 3000.4 where the arrow is substituted for the green light may be varied so that the head of the arrow points to any position on the 90° arcs shown in diagram 3005 or 3006, provided that there is a difference of not less than 45° between the directions in which paired arrows point.
The direction of either of the green arrows included in diagram 3000.4, where the sign shown in that diagram has been varied by the substitution of a green arrow for the tram signal aspect, may be varied so that the head of the arrow points to any position on the 45° arcs shown in diagram 3007 or 3008 provided that there is a difference of not less than 45° between the directions in which paired arrows point.
The direction of either of the green arrows included in diagram 3000.6, where the sign shown in that diagram has been varied by the substitution of a green arrow for the tram signal aspect, may be varied so that—
when the arrows are illuminated and extinguished simultaneously, the head of the upper arrow may point in any direction on the 135° arc and the head of the lower arrow may point in any direction on either of the two 45° arcs shown in diagram 3011.1, provided that there is a difference of not less than 45° between the directions in which the two arrows point ; and
when the arrows are illuminated and extinguished independently, the head of either of the arrows may point in any direction on the two 180° arcs shown in diagram 3011.2, provided that there is a difference of not less than 45° between the directions in which the two arrows point.
