The Traffic Signs Regulations and General Directions (TSRGD)
Following a government consultation in 2014 the Traffic Signs Regulations and General Directions 2016 were made on 16 March 2016, coming into force on 22 April 2016. This Instrument consolidates, with substantial amendments, the Zebra, Pelican and Puffin Pedestrian Crossings Regulations and General Directions 1997, the Traffic Signs (Temporary Obstructions) Regulations 1997, the Traffic Signs Regulations and General Directions 2002 and the School Crossing Patrol Sign (England and Wales) Regulations 2006. Part 1 is the Traffic Signs Regulations 2016 and Part 2 is the Traffic Signs General Directions 2016.
TSRGD 2016 prescribes the designs and conditions of use for road studs in the UK and specifies the products classification and level of performance. The Table below is taken from TSRGD 2016 and shows the requirements that must be met. Where mentioned that “British Standard requirement or test specification and class” this means the road studs must meet the requirements of BS EN 1463-1 2009 on retroreflecting road studs when read with BS EN 1463-2 2000 on road test performance for retroreflecting road studs.
