The Nordschleife has remained a one-way, public toll-road for nearly 80 years except when it is closed off for testing purposes, training lessons or racing events. Since its opening in 1927, the track has been used by the public for the so-called "Touristenfahrten," i.e. to anyone with a road legal car or motorcycle, as well as tour buses, motor homes or cars with trailers. It is opened mainly on Sundays, but also on many Saturdays and weekday evenings. During the winter months, depending on weather conditions and maintenance work, the track may be closed for weeks.
During Touristenfahrten sessions, German road law applies. There is no general speed limit, however speed limits exist in certain areas in order to reduce noise and risks. As on public roads, passing on the right is prohibited, and the police take an extremely dim view of poor driving as they prosecute offenders with the aid of helicopters.
