This application enables people to look up the areas of cities which are restricted for being used by cars limited by their specific emission profile. The app shows the outline of the low emission zones and provides additional information about dates or special regulations such as for vehicles registered abroad. Moreover, the user can use the FAQs to read about emission groups, fine particles, stickers for cars or motorbikes, punishments, exception permits and many more. Further, there are several links included pointing to external websites which serve more information to read through.
