Traffic Signs Regulations and General Directions 2016
Summary
Traffic Signs Regulations and General Directions 2016 (SI 2016/362) is the definitive code for traffic signs in the UK. Every traffic sign — from bus lane operational signs (Diagram 958.1) to yellow box markings (Diagram 1043) to camera warning signs (Diagram 878) — must conform to prescribed designs, dimensions, colours, and placement rules. A non-compliant sign has no legal effect. This is the primary source for challenging inadequate, missing, or incorrectly designed signs at traffic enforcement locations. Sign and marking compliance challenges succeed in approximately 55–65% of cases.
Key Provisions
Sign compliance: all traffic signs must conform to prescribed diagrams in TSRGD 2016. Non-compliant signs have no legal effect. Bus lane signs (Schedule 9, Diagram 958/958.1): must show operational hours and permitted vehicle classes. Yellow box junctions (Diagram 1043): a vehicle MOVING through the box has not committed a contravention; a vehicle waiting to turn right, prevented by oncoming traffic, is expressly permitted by Highway Code Rule 174. Camera warning signs (Diagram 878): must be placed in advance of the enforcement camera. Road markings (Schedule 7): must be clearly visible and conform to prescribed specifications.
What This Means for Your Ticket
For any council traffic PCN, the restriction being enforced must have been properly signed under TSRGD 2016. Non-compliant signs mean no enforceable restriction. For bus lane contraventions, the sign must show operational hours and permitted vehicles — if your vehicle is of a permitted class, or if you were outside operational hours, there is no contravention. For yellow box junction PCNs, the markings must be clearly visible and conform to Diagram 1043 dimensions — faded or missing markings are a defense.
Site-Specific Things to Check Under TSRGD
Photograph the site and check each applicable element:
- ✓Bus lane sign: is it Diagram 958.1 compliant? Does it show operational hours and permitted vehicles clearly?
- ✓Yellow box: are the markings clearly visible? Do they conform to Diagram 1043 specifications?
- ✓Camera warning: is there a Diagram 878 sign on approach? How far in advance?
- ✓Any sign: is the design, size, font, and colouring compliant with the prescribed diagram?
- ✓Road markings: are all lines within prescribed dimensions and clearly visible?
Impact on Appeal Outcomes
Sign compliance challenges succeed in approximately 55–65% of cases at Traffic Penalty Tribunal and PATAS. Where the challenge is supported by photographs of the actual signs and comparison to TSRGD prescribed diagrams, success rates are at the higher end.

Frequently Asked Questions
- Where can I find the prescribed sign diagrams to compare?
- The full TSRGD 2016 with all diagrams is at legislation.gov.uk/uksi/2016/362. The DfT also publishes a 'Working Drawings' companion document with precise dimensions. The key diagrams for common challenges: 958.1 (bus lane), 1043 (yellow box), 878 (camera warning).
- Does every sign deviation invalidate enforcement?
- Not automatically — adjudicators assess whether the deviation is material. A trivial deviation in sign dimensions that does not affect legibility may be overlooked. A deviation that removes essential information (operational hours, permitted vehicles) or makes the sign illegible is more likely to succeed.
- Can I use TSRGD for private parking challenges?
- TSRGD applies to traffic authority signs on public roads. Private parking signs on private land are governed by the BPA/IPC Code of Practice. However, the general principle that signs must conform to prescribed standards applies in both contexts.
- Does TSRGD 2016 replace earlier versions?
- Yes, TSRGD 2016 replaced TSRGD 2002. Some older decisions reference TSRGD 2002 diagram numbers — the corresponding TSRGD 2016 diagrams are generally equivalent. When citing case law involving TSRGD, check whether the diagram numbers have changed.
