No through road for polluting cars

It's "no entry" for some of Germany's most polluting cars as they are banned from some city centres.

Drivers are now required to get their vehicle's emissions tested and display an environment sticker if they want to drive in the so-called "environment zones" in the inner-city areas of Berlin, Cologne and Hanover. The new measures are designed to cut pollution which has been linked to asthma and other conditions. (video at Reuters)
