Traffic Signs Regulations and General Directions
The Traffic Signs Regulations and General Directions (commonly abbreviated to TSRGD) is the law that sets out the design and conditions of use of official traffic signs that can be lawfully placed on or near roads in Great Britain (England, Scotland and Wales) and the Isle of Man. The regulations were the result of the review of British road signage carried out by the Worboys Committee.
The TSRGD was introduced on 1 January 1965 to implement the re-signing recommendations of the Worboys Committee of 1963. The regulations were the result of the review of British road signage carried out by the Worboys Committee with signage designs and typeface developed by Jock Kinneir and Margaret Calvert. Since 1964, TSRGD has been revised and re-issued several times since 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.
