The Senedd passed The Restricted Roads (20 mph Speed Limit) (Wales) Order 2022 legislation in 2022. This means speed limits on most restricted roads will reduce from 30mph to 20mph from September 2023.

Restricted roads include street lights placed no more than 200 yards apart. They are usually located in residential and built-up areas with high pedestrian activity.

Reducing the default speed limit from 30mph to 20mph in these areas could see a number of benefits, including:

  • a reduction in road collisions
  • more opportunities to walk and cycle in our communities
  • helping to improve our health and wellbeing
  • making our streets safer
  • safeguarding the environment for future generations.

Wales will be one of the first countries in the world and the first nation in the UK to introduce legislation to have a 20mph speed limit on roads where cars mix with pedestrians and cyclists. 

These changes support:

Next steps

We recognise not all roads currently at 30mph will be suitable to change to 20mph (known as exceptions) and are working with the Welsh Government and SWTRA (South Wales Trunk Road Agent) to identify these routes prior to September 2023.
