Traffic Signs Design Principles
- This section sets out the principles governing the use of road numbers and destinations on directional traffic signs.
- The design and application of directional signing shall accord with the requirements of the Traffic Signs Regulations and General Directions (TSRGD) and relevant Department for Transport guidance.
- Direction signage is structured to provide clear and consistent guidance to motorists through the use of a defined hierarchy of routes and destinations.
Road Hierarchy and Route Classification
- The signing system uses colour coding to indicate the classification and relative importance of routes, assisting drivers in following appropriate networks.
- The principal colour conventions are as follows:
- a.Motorways – Blue background
- b.Primary Routes – Green background, or green panels on white signs
- c.Non-Primary Routes ('A', 'B', 'C' and unclassified roads) – White background
- Direction signs may incorporate coloured panels (“patching”) to indicate the status of connecting routes along which destinations can be reached.
