Cabinet Secretary, there is growing evidence and support for a default 20 mph speed limit in urban areas, with provision for lower or higher limits on particular roads. The evidence is that there would be fewer crashes, fewer casualties, fewer fatalities, and that traffic would move more freely, with lower emissions. It has strong public support, and it's estimated that tens of millions of pounds would be saved. It also links with active travel. In Bristol, for example, where they've rolled out such a speed limit, more people are walking and cycling to school and work, and, in fact, 25 per cent of Britain's urban areas are now 20 mph areas. There is a strong '20's plenty' campaign, calling on Welsh Government to introduce a 20 mph default speed limit in urban areas, and this is supported by the Organisation for Economic Co-operation and Development, the World Health Organization, Public Health Wales, Sport Wales, and Brake. Will Welsh Government now introduce this policy in Wales?
