Under section 95 of the Road Traffic Act 1961 the provision of traffic signs on the public roads is a matter for each road authority. I have given directions and guidance to road authorities in the Traffic Signs Manual on the provision and use of traffic signs. The revised Chapter 8 of the Manual, which was issued to all local authorities in February 2007, provides for clear guidance on the implementation and removal of all signage associated with road works. It is a matter for the road authority to determine the location of traffic signs to ensure that clear and effective signing is in place for the efficient operation of the road network, for the enforcement of traffic regulations and for road safety purposes.
