§ Mark TamiTo ask the Secretary of State for Transport, Local Government and the Regions what guidance he gives to local authorities on (a) installing road bumps on established roads, (b) painting speed limits in block form on roads and (c) other traffic calming measures. [21458]
§ Mr. JamiesonThe Department provides local authorities with guidance and advice on traffic calming, including road humps, through our Traffic Advisory Leaflets. We are also preparing a Local Transport Note on the design and effectiveness of traffic calming measures. Unlike many other traffic calming measures, painted speed limits on the road (carriageway roundels) require authorisation from the Secretary of State. This is due to their limited effect on vehicle speeds. As such no specific guidance exists, although we offer advice where this is required.
