20 mph signs, the legalities.

David Bilyk made this Freedom of Information request to Nottinghamshire County Council

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was successful.

Dear Nottinghamshire County Council,

Please provide me with any information you hold regarding the legal status of the traffic signs which consist of a circular grey border within which are displayed the figures '20' (as seen, for example, on Nottingham Rd in Keyworth), including (but not limited to) whether they are authorised by the Department for Transport. Also has there been a TRO for the change in speed?

Same as the signs in this document - http://www.nottinghamshire.gov.uk/media/...

Yours faithfully,

David Bilyk

FOI, Nottinghamshire County Council

Dear Mr Bilyk

I am writing to you in reply to your Freedom of Information Act (FOIA)
request to Nottinghamshire County Council about 20mph speed limit signage.
Firstly I apologise for the delay in replying to you and hope that it has
not caused any inconvenience. I have the following information.


[1]Circular 01/2013 ‘Setting Local Speed Limits’ issued by the Department
for Transport (DfT) in January 2013 set out the responsibilities and the
framework highway authorities should follow when reviewing and setting
local speed limits.


Given the high level of pedestrian activity and the high volumes of
vulnerable road users at school start and finish times the County Council
introduced advisory 20mph speed limits outside schools where it was
feasible to do so. National research has shown that where the mean speed
is at or below 24mph introducing signing alone is likely to lead to
general compliance with the new speed limit. As the speed limits are
advisory, there is no associated Traffic Regulation Order (TRO).


A report and the relevant appendices to implement 20mph speed limits
outside schools was approved by Transport and Highways committee on 17th
September 2013:  

-          [2]T&HC report – implementing 20mph speed limits;

-          Appendix 1 – [3]summary of DfT guidance ‘Setting Local Speed

-          [4]appendix 2 – advisory 20mph signs to be used outside

-          Appendix 3 – [5]schools for delivery in 2013/14. This
identified the first 50 schools for delivery in 2013/14.

-          Appendix 4 -  [6]schedule of speed surveys outside schools to
be undertaken. This identified the schedule of when speed surveys would be
undertaken outside each school.  


There are two different types of 20mph speed limits that were installed:

 1. Most schools are in residential areas so advisory 24 hour speed limits
were installed outside schools that are located on residential roads
with signs only. The signs were approved by Transport and Highways
committee on 17^th September 2013 [[7]T&HC report – implementing 20mph
speed limits and pages 1 and 2 of [8]appendix 2 – advisory 20mph signs
to be used outside schools] following consultation with the road
safety team.
 2. For schools located on main traffic distributor roads, advisory
variable speed limits were installed (with flashing amber warning
lights with a sign beneath them stating ‘20 when lights show’). The
variable speed limit signs used are DfT approved signs and were
approved by Transport and Highways committee on 17^th September 2013
[[9]T&HC report – implementing 20mph speed limits and page 3 of
[10]appendix 2 – advisory 20mph signs to be used outside schools].
 The advisory 20mph limits operate during school start and finish
times, Monday-Friday during term-time only; and 30mph (or appropriate)
limits at all other times.


If you have any queries or concerns then please contact me. Please
remember to quote the reference number above in any future communications.
