Question to the Department for Transport:

To ask the Secretary of State for Transport, if she will require local highway authorities to conduct an annual review the effect of the introduction of 20 mile per hour speed limit zones on (a) road accidents and (b) traffic flows in those areas.

The Department for Transport does not have any plans to impose any new requirements on local traffic authorities. They are responsible for taking the decisions in respect to the speed limits on their roads, because they have the local knowledge making them the best placed to do so.

The Department for Transport issues non-mandatory guidance to English local authorities on setting speed limits, to assist their decision making. The guidance suggests that they keep their speed limits under review with changing circumstances.
