It is perfectly possible that it can be done, but I just do not see the point. It would create extra confusion, and there would be a plethora of signs at the border where currently there is none. There would also have to be a huge information exercise, which would, in many cases, fail to get to the users of those roads.
Welsh devolution was meant to improve the lives of people, but it is very difficult to see how the devolution of a national speed limit, among other items in the Bill, would bring that about. It surely needs to be accepted that this is a matter most sensibly overseen at UK level. I respectfully urge the Government to reconsider.
