10. Specification for Signs
1.77 Specifications for construction of signs, bollards and their supports are contained in the current edition of British Standard No 873, The Construction of Road Traffic Signs and Internally Illuminated Bollards.[1] No signs should be purchased unless they comply with this standard or with the equivalent standard of a European Economic Area member state.
11. Illumination and Reflectorisation of Signs
1.79 The requirements for the illumination and/or reflectorisation of traffic signs are specified in the Regulations. Site checks should be made during darkness to ensure that reasonable visibility standards are achieved and if a reflectorised only sign at a particular location does not perform adequately, it may be directly illuminated.
1.80 For reflectorised signs, button reflectors may only be used on round hazard markers. Reflectorisation on most types of signs must be whole area reflectorisation (see regulations 18 to 21 in the Traffic Signs Regulations and General Directions 2002).
