Guidelines for Setting Local Speed Limits in Wales

The guidelines are to be used for setting all local speed limits on single and dual carriageway roads in both urban and rural areas. It brings together the main features of other published guidance on speed limit related issues including speed related road traffic regulation and signing, street lighting, speed limits in rural communities, and 20mph speed limits and zones.

Increasing the use of 20mph limits across Wales is a One Wales commitment, we are working with Local Authorities to extend 20mph schemes and the safer routes to schools/in communities programme. The introduction of 20mph limits is generally most appropriate for non-trunk roads, although the new guidance also introduces the potential for time-bound 20mph limits on trunk roads such as at peak periods when children are either going to or from school.
