Local authorities in Wales are currently reviewing which roads could revert from 20mph to 30mph. This review process has not been completed by all local authorities. Welsh Government at present are not able to state what percentage of 20mph roads have returned to 30mph since January 2025 as Welsh Govt are waiting for the review process to complete.
