The TSRGD came into force on 1 January 19651 to implement the re-signing recommendations of the Worboys Committee of 1963, with signage designs and typeface developed by Jock Kinneir and Margaret Calvert. Since 1964, the TSRGD has been revised and re-issued several times to introduce new signage rules and features reflecting changes in road operations. The current edition of the regulations came into force on 22 April 2016, with minor amendments in England and Wales in 2017.23
The Traffic Signs Manual4 is a companion guide to the TSRGD which provides guidance to highway engineers about how and where to use traffic signs, including the size of sign to use (which depends on the speed of vehicles passing the sign). It was first issued in 1965 in a loose-leaf binder and was continuously updated.5 Individual chapters were also published in book form and these became the only format from 1980 onwards.
