I welcome the hon. Gentleman’s support and that of his constituents for what the coalition Government is doing. Following on from the document “Signing the Way”, which I launched in October 2011, we have provided every English authority with a traffic sign authorisation to use speed limit repeater signs in place of physical measures in 20 mph zones, and that will reduce the costs for local authorities in Northamptonshire and elsewhere. This authorisation also enables local authorities to place advisory part-time 20 mph speed limit signs in the vicinity of schools without the need for central Government approval. Councils can also now use roundels on the road to replace some upright signs.
