 Use of reflecting material and studs with reflectors on road markings

25.—(1) The road markings shown in diagrams 1011 to 1014 shall be illuminated with reflecting material, and studs incorporating reflectors shall be fitted—

(i) between the two lines constituting the marking shown in diagram 1013.1 unless that marking is placed on any automatic half barrier level crossing within the meaning of Regulation 11(2)(a) or is placed on a length of the road falling within a distance of 90 metres measured from the transverse stop line provided in association with any such crossing and in conformity with diagram 1001, and

(ii) either along the length of, or between, the said two lines whenever the marking so shown is placed on any such level crossing or length of that road as aforesaid.

(2) Subject to the foregoing provisions of this Regulation, any road marking may be illuminated with reflecting material and studs incorporating reflectors may be fitted to the markings shown in diagrams 1003,4 to 1012.1, 1025.2, 1025.3 and 1040 to 1042 in such a manner that no such stud shall be fitted to any mark coloured white and forming part of any of the markings so shown as aforesaid but shall be applied to the surface of the carriageway in the gap between any two such marks:

Provided that in the case of the markings shown in diagram 1012 or 1012.1, the said studs shall, if fitted, be applied to the surface of the carriageway at the side of and adjacent to the line shown in the diagram.

(3) Reflectors incorporated in studs shall be white except that in the case of reflectors fitted to the markings shown in diagrams 1009 to 1012.1, 1025.2, 1025.3, 1041 and 1042 they may be—

(a) red where the near side edge of a carriageway is indicated to drivers of approaching motor vehicles,

(b) amber where the offside edge of a carriageway which is contiguous to a central reservation is indicated as aforesaid, and

(c) green when fitted to the markings shown in diagrams 1009, 1010, 1025.2 and 1025.3 where the edge of any part of the carriageway available for through traffic at a road junction, a lay-by or a parking place is so indicated as aforesaid.

In this Regulation "central reservation" means any provision made in a road (not being the provision of a street refuge) for dividing the road for the safety or guidance of vehicular traffic.

Height of road markings and size of studs

26.—(1) Non-depressible studs incorporating reflectors and fitted as a part of a road marking shall either be in the shape of a circle having a diameter of not more than 20 millimetres in excess of the width of the road marking to which the studs are fitted or of a rectangle having a length of not more than 250 millimetres and a width of not more than 20 millimetres in excess of the width of the road marking to which the studs are fitted.

(2) Subject to paragraph (3), no road marking shall project above the surface of the carriageway in the immediate vicinity more than 6 millimetres at any point unless it is a road marking fitted with non-depressible studs when those studs shall not project above the said surface more than 18 millimetres at the highest point nor more than 6 millimetres at their edges, or unless it is the road marking shown in diagram 1003.4 when that marking shall not project above the said
