Speed limit issues were devolved to the Welsh Government in the Wales Act 2017, which amended the Road Traffic Regulation Act 1984. In terms of the 20mph speed limit, it is disappointing that the Welsh Government seems to be ignoring its own impact assessments, which suggest that the damage to the Welsh economy could be as high as £4.5 billion. The UK Government does not have any current plans to change the national speed limits, or to introduce 20mph as the default speed limit for urban areas in England.
