New 20mph zones are not going to be introduced along the M4 motorway. It was, of course, an April Fool joke.
In our article, we said the speed limit was going to be permanently reduced to 20mph on some of the busiest sections of the motorway as part of further Welsh Government measures to reduce pollution in surrounding built-up areas.
The limit had already been cut to 50mph on some parts of the road in a bid to manage congestion, improve journey times, reduce accidents and improve air quality. But the new move - if real - would have made Wales the only country in the world to have such a low speed limit enforced on a motorway.
