20mph: A new default speed limit for Wales

Commencing 17th September 2023, a default 20mph speed limit for drivers will be implemented on ‘restricted roads’ across Wales. This means most 30mph speed limits will reduce from 30mph to 20mph.

‘Restricted’ refers to roads which have street lights placed no more than 200 yards apart. They are usually located in residential and built-up areas with high pedestrian activity.

A Welsh public health study estimated that the 20mph default speed limit could result in:

  • 40% fewer road collisions
  • saving 6 to 10 lives every year
  • and avoiding 1,200 to 2,000 people being injured every year

The Senedd passed The Restricted Roads (20mph Speed Limit) (Wales) Order 2022 legislation last year. Under this legislation, local authorities and the two trunk road agencies, will decide which roads should remain at 30mph.
