Lower speed limits could be introduced on two sections of Welsh roads to tackle pollution.
The BBC reports that the Welsh government wants to reduce nitrogen dioxide (NO2) concentration on the A470 between the Coryton and Nantgarw interchanges on the outskirts of Cardiff, and on the M4 between junction 43 Llandarcy and 44 Lon-las in the Neath-Swansea area, and is looking to 50mph limits as a way of doing it.
But the report does say it is reviewing “all practical options” and that it is too early to say if it would lead to more 50mph zones.
A full public consultation will be undertaken on shortlisted options.
Slower speeds have already been imposed in pollution hotspots around where drivers are used to doing 70mph, enforced by Jenoptik average speed cameras.
