The Welsh government has decided to make permanent five 50mph zones on the M4 motorway to improve air quality.

The Freight Transport Association’s Sally Gilson responded saying: “The 50mph zones were introduced as a temporary measure to help ease the air quality issues along the five areas identified by the Welsh Government.

“FTA’s concern is that the Welsh Government has now announced that the zones will be permanent. Previous data has shown that air quality target levels will be achieved without any additional measures, due to fleet replacement and the increase in Euro 6 vehicles. The A48 was projected to achieve target levels by this year with the A494 the latest to achieve target in 2022.”
