A campaign launched at the start of Road Safety Week is appealing to drivers and authorities in London and the South East to GO 20, to bring about a 2012 legacy of safe walking and cycling.
Brake, the road safety charity, is appealing to drivers to slow down to 20mph or below in communities and calling for widespread 20mph limits in built up areas, so children and adults can walk and cycle for their health and enjoyment, and for cheap and sustainable travel, without being endangered.
