Road signs of Duchessland in 1955

In 1955, most road signs became pictorial, while some signs (such as speed limit signs and stop signs) are simply written in English. It also adopted the European-style "no parking" and "no stopping" signs, as well as the "give way" sign, which is similar to Australian yellow circle standard. Warning signs of this time are compliant with the United States' MUTCD standards. Duchessland's road sign manual of 1955 also includes the Belisha Beacon, first introduced in 1943. Road signs used the imperial system of units.
