20mph will become the default speed limit on 30mph roads in Wales, from 17 September 2023.
It follows Senedd approval of The Restricted Roads (20 mph Speed Limit) (Wales) Order 2022 (opens in a new tab) legislation.
The Welsh Government is making this change for a number of reasons, including:
Not all roads currently at 30mph will be suitable to change to 20mph. These roads will be known as exceptions (please see the link below for more information on these).
Like all highway authorities in Wales, we must follow the statutory process on traffic regulation orders to make exceptions.
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.
Eight communities were selected for the first phase of the 20mph national programme, including St Dogmaels in Pembrokeshire: Pilot Project, St Dogmaels (opens in a new tab)
