Welcome to our web pages dedicated to providing information about the Welsh Government plans to set a national 20mph default limit for cities, towns and villages.

Wales is joining the many countries where 20mph or 30km/h limits are becoming the norm for urban and village streets. But unlike the street by street approach of the rest of the UK, it is taking a smarter route by setting 20mph as the national urban/village default with exceptions decided by local authorities. It has all the benefits of a national and consistent standard combined with local flexibility.

The legislation for this has already been passed and the new limit becomes effective on 17th September 2023. The Welsh Government have dedicated 20mph pages on their website.

We have brought into this section any previous briefings that referenced the Welsh 20mph policy.

Here you will find a range of pages which will help understand why and how the changes are to be made. 

Please expect these pages to be developed as time goes by.

If you have any suggestions as to how the information can be improved then please email [email protected].
