The Traffic Signs Regulations and General Directions (TSRGD) 2016 prescribes the design and condition of use for traffic signs on or near roads in England, Scotland and Wales.
Schedule 3 of the TSRGD 2016 covers upright signs that indicate regulatory requirements for moving traffic.
Schedule 3 prescribes regulatory roundels and follows a similar format to Schedule 2. However, unlike warning triangles, roundel sizes remain individually prescribed. The full size range for sub-plate x-heights applies in all instances.
The title of each working drawing reflects the respective Schedule, Part and Item in TSRGD 2016. The part of the title in parentheses refers to the TSRGD 2002 working drawing that it has replaced.
