Since 01 January 2012 only vehicles bearing the green sticker may enter the low-emission zone.
For vehicles registered in or outside Germany, the required environmental badge, indicating the relevant emissions group, can be obtained at www.umwelt-plakette.de.
For vehicles without an 'environmental badge' access to the exhibition grounds is only possible via Tor West (West Gate) and Tor North (North Gate). These gates can be reached via the A648 motorway (coming from the A5) taking the Rebstockexit or via the Katharinenkreisel (roundabout).
The Rebstock multi-storey car park can be reached without an 'environmental badge' .
