In December 1952 the West German legislature voted to abolish "all" national speed limits, seeing them as Nazi relics, reverting to State-level decisions. National limits were reestablished incrementally. The urban limit was enacted in 1956, effective in 1957. The limit on rural roads—except autobahns—became effective in 1972.
