RETROFIT BUSES AND AVOID PENALTIES
Public buses and travel coaches are also subject to German federal emissions sticker regulations (“window sticker” regulation) and therefore not excluded from the driving bans imposed in German environmental zones.
Retrofitting a Twintec particulate filter eliminates the need to purchase an expensive new bus.
The green environmental sticker is also required in order to drive in some European cities outside of Germany, as well. Anyone caught without the sticker on their windscreen can expect to pay a heavy fine.
So owners who retrofit their Euro-II or Euro-III buses with a particulate filter from Twintec are always driving on the safe side, also throughout the rest of Europe.
