We have introduced a default 20mph speed limit on restricted roads across Wales.

Restricted roads are usually located in residential and built-up areas where there are lots of people. They often have street lights on them, placed no more than 200 yards apart.

We made this change to:

  • reduce the number of collisions and severe injuries from them (also reducing the impact on the NHS from treating the people who are injured)
  • encourage more people to walk and cycle in our communities
  • help to improve our health and well-being
  • make our streets safer
  • safeguard 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 default 20mph speed limit on roads where cars mix with pedestrians and cyclists. 

What did we do

We worked with highway authorities, Trunk Road Agents (TRAs), who operate the strategic road network, and local authorities, who are responsible for county roads.

Not all roads with a 30mph limit are suitable to change to 20mph. These roads are known as exceptions. Local Authorities considered which roads should remain at 30mph. There will be 30mph signs in place to tell you this. 

A map on DataMapWales that shows which roads would stay at 30mph. 

All highway authorities must follow the statutory process on traffic regulation Orders to make exceptions. 

Early impacts

Eight communities were selected as first phase settlements to introduce 20mph speed limits:

  • St Dogmaels, Pembrokeshire
  • Llanelli North, Carmarthenshire
  • St Brides Major, Vale of Glamorgan
  • Central North, Cardiff
  • Cilfrew Village, Neath Port Talbot
  • Abergavenny, Monmouthshire
  • Severnside, Monmouthshire
  • Buckley, Flintshire
