On France’s roads, a new traffic sign could cause confusion among German tourists: A separate lane for soccer fans? The white rhombus on a blue background, often seen as the logo of a German soccer club, has a different purpose, however: it marks lanes on which the environmental balance in road traffic is to be improved by means of more efficient vehicle use. Carpools, buses, e-cars – they all have a „private“ lane here. In and around Lyon, Grenoble and Strasbourg, such lanes have been in place for several months; Rennes and Nantes are working on implementation.
