Environmental Sticker in Germany
The environmental zone sticker is mandatory in Germany. These windshield stickers are in three colors, i.e. green (shows environmentally acceptable vehicle), yellow (less acceptable than green), and red (still acceptable). A fourth colored sticker in blue is under consideration also. From the year 2018, there are some areas where diesel vehicles are not allowed to enter. Catalytic converters are mandatory to enter these zones. Vehicles found in an environmental zone without an appropriate sticker are subject to a €10 fine. A total absence of an environmental zone sticker can cost €100 fine.
These stickers have vehicle number written on them.
