Since its opening in 1927, the track has been used by the public for the so-called Touristenfahrten, i.e. anyone with a road-legal car or motorcycle, as well as tour buses, motor homes, or cars with trailers. It is opened every day of the week, except when races take place. The track may be closed for weeks during the winter months, depending on weather conditions and maintenance work. Passing on the right is prohibited, and some sections have speed limits; the normal traffic rules (StVO in German) apply also here.
