Road Signs and Markings

Question

To ask His Majesty's Government what discussions they have had with National Highways regarding signage at night when diversions on major trunk roads arise from temporary carriageway closures during planned maintenance.

Answer

The Department maintains appropriate engagement with National Highways (NH), the delegated authority for the operation of the strategic road network, within the framework of the New Roads and Street Works Act 1991 and the Traffic Management Act 2004. National Highways uses signs to ensure safe and suitable movement of traffic around a planned closure. Diversion signs are provided at every decision point along an agreed diversion route. These will usually be temporarily installed metal plate signs which complement diversion symbols on permanent signs to guide traffic. The need for repeater diversion signs is also considered, determined by the risk of drivers deviating from the route.

In the hours of darkness diversion signs are illuminated or reflectorised to help visibility and readability.
