Changes in TSRGD 2016
6.2
Those roundels that may be mounted within traffic signal heads – and the associated sign specific provisions and directions – have been included in Schedule 14 which covers traffic signals.
6.3
Those directions previously prescribing the placing of two signs indicating the beginning and end of a prohibition, restriction or requirement have been removed. Only one sign is now required although authorities will need to consider if this is appropriate in individual cases. There is still a requirement to place a terminal sign as close as possible to the point where the restriction begins and ends.
6.4
The No Entry sign to diagram 616 and the road marking to diagram 1046 when used at safety-critical locations approved by the Secretary of State, previously did not need a traffic order. The option to seek this approval has been removed, so the sign and road marking will now always require a traffic order. Existing site approvals will remain valid, unless written notice of withdrawal has been made.
6.5
The "Only" plate to former diagram 953.2 has been withdrawn, as this legend is no longer used under 'bus gate' and 'tram gate' signs to diagrams 953 and 953.1. This series of signs has been extended to include all permutations of exemptions for cycles, motorcycles and taxis.
6.6
The permitted supplementary plate exception legends for use in combination with the 'No entry' (diagram 616) are now one of "trams", "buses", "local buses", "cycles", "buses and cycles" or "local buses and cycles" where "and" may be varied to "&".
6.7
The "no right turn" and "no left turn" signs (diagrams 612 and 613) may now have time plates. The use of these is likely to be appropriate where the prohibition on turning applies during peak hours and where there are no dedicated traffic lanes for turning traffic. The use of double-headed arrows (diagram 1038) in traffic lanes should be avoided.
6.8
Where the road marking to diagram 1044.2 (now a permitted variant of diagram 1043) is placed on the carriageway at a road narrowing, the requirement to also place diagrams 615 and 811 has been removed. However, it is strongly recommended that where the road marking is provided, the upright signs are also used.
6.9
The requirement to apply direct illumination during the hours of darkness to regulatory roundels, where placed on retroreflective self-righting bollards within a street-lit area, has been removed. Instead these signs must now be reflectorised as a minimum. It remains that those signs mounted on internally illuminated bollards must be directly lit.
6.10
Signs for speed limits are prescribed in Schedule 10.
6.11
A new roundel diagram 956.1 has been added for routes for use by pedal cycles, horses and pedestrians only. A second new roundel, diagram 956.2, is prescribed for routes that may be used only by pedal cycles, horses, horse-drawn vehicles and pedestrians.
6.12
The regulatory signs to diagrams 629 and 629.2 showing height and width restrictions in imperial units of measurement only have been withdrawn. All new
