20mph streets

20mph speed review

Between April and July 2024, Welsh government are asking for people's thoughts on 20mph speed limits. 

They're looking to revise the guidance on which local roads can be exempted from 20mph.

If you have any feedback on how 20mph has been implemented on a particular street in Newport, you can let us know by completing our form.

Complete our 20mph review form

We will log your feedback and review it once new exceptions guidance is available from the Welsh government.

We expect to receive this guidance by summer 2024. 

New 20mph default speed legislation

Welsh government introduced a default 20mph speed limit on restricted roads in Wales in September 2023. 

These are roads with streetlights no more than 200 yards apart, usually located in residential and built-up areas.

Newport maps and 30mph exceptions

Maps showing which streets in Newport defaulted to 20mph, and which streets had limits set at 30mph were published on Welsh government’s Data Map Wales site, and can be viewed by clicking the link below.


The streets with 30mph speed limits are known as exceptions, as they are not subject to the new default limit.
