Polish road sign D-39: permissive speed limits. This is the version of the sign that was valid from 1993 to 1999; introduced by the Regulation of the Ministers of Transport and Maritime Economy and Internal Affairs of January 11, 1993 on road signs and signals (Dz.U. z 1993 r. nr 32 poz. 145), which entered into force on May 27, 1993 and was annulled on July 1, 1999 by the Regulation of the Ministers of Transport and Maritime Economy as well as Interior and Administration of June 21, 1999 on road signs and signals (Dz.U. z 1999 r. nr 58 poz. 622). In 1999, a new look of this sign came into force, which is basically used to this day.
