Speeding is anti-social and often requires police intervention. However, local initiatives may be used to encourage drivers to slow down.


Education, training and publicity (ETP)

Road safety education, training and publicity campaigns aim to change habits and driving attitudes. Traditionally used on their own, they can also support the introduction of physical traffic calming measures.

Advertising and publicity campaigns can quickly reach a large audience and enable the delivery of simple measures in a coordinated manner.

Collisions cannot be prevented through simple engineering measures for numerous reasons such as drivers being under the influence of alcohol or that the severity of the collision is far worse simply because the occupants of a vehicle have failed to wear a seat belt. In many cases the solution may be through better education, therefore Transport for Buckinghamshire run campaigns, courses and awareness raising initiatives.

More details can be found on our road safety page.

Speed education campaign

TfB promote a speed reduction campaign which aims to tackle the problems caused by inappropriate and excessive speed in local communities. The campaign consists of educational campaign materials and online media to influence behaviour on the road and ultimately reduce speeding incidents.

Community speedwatch

Thames Valley Police run a Community Speedwatch Scheme which may operate in your area. This is a scheme where a Speed Detection Radar Device (SDR) is used at the roadside and registration numbers of vehicles that have been seen speeding are noted down.

The information is fed into a TVP database and a warning letter is issued to the registered vehicle owner. Should the vehicle be identified speeding on a subsequent occasion, a further letter will be sent to the owner informing them that the information has been passed to Roads Policing (RP) for possible further action.

A community can operate this scheme with volunteers, either in partnership with neighbouring parish councils, who may already own Speedwatch equipment, or by purchasing their own equipment. Police may also have equipment which can be used by trained volunteers to carry out a vehicle speed data gathering exercise.

For further information on Community Speedwatch or to find out the availability of this equipment, please contact your local Neighbourhood Policing Team online or by telephoning 101.

Complaints regarding anti-social driving behaviour are a police matter and should be reported to them.


Reporting speeding drivers

Thames Valley Police (TVP) is responsible for all matters concerning enforcement of traffic laws including speeding.

Concerns regarding speeding should initially be dealt with by the relevant Thames Valley Police (TVP) Neighbourhood Team. You can contact the police online or by telephoning 101.

Please note that we have no powers to enforce speed limits.


Engineering solutions

It is important to establish exactly what the problem is, as very often concerns are based on perception rather than fact.

Parish councils and community groups can request a speed survey from the Traffic Information Data Team at Transport for Buckinghamshire. The cost is £412 + VAT for a 7 day survey. Requests can be made via our contact us form or by calling 01296 382 416.

If there is evidence of speeding or speed related collisions Parishes may apply for a permanent or moveable vehicle activated sign (VAS).

Alternatively, TVP may have their own version of these signs which organisations and community groups can borrow or hire. This can be done by contacting your local Neighbourhood Policing Team online or by telephoning 101.

Traffic calming for example speed cushions or other physical engineering schemes may be funded through local community funds. Find out more about Community Boards


Speed limits

Changing a speed limit

A countywide review of speed limits for all public roads in Buckinghamshire was completed in 2012. The roads were assessed and new speed limits installed, (where appropriate); in accordance with the National speed limit policy. Following this comprehensive review, we are unable to justify funding any further speed limit changes across the county – higher priority has been given to the funding of road maintenance.

Our current policy on requests for changes to speed limits is set out in Key Decision Report PT01.13.

The basic principles described in this report are that all requests for changes to speed limits, (including 20mph limits), will need to be funded either:

  • directly by individual parish or town councils
  • by a Local Area Forum of local councils via the Local Priorities Budget process
  • from independent sources

The only exceptions to this will be speed limits introduced as part of a casualty reduction scheme or by a Section 106 developer funded agreement and a few other specific speed limits which are detailed in the report.

Irrespective of the funding source, requests for speed limit changes will only be formally consulted upon and implemented if they comply with the National guidance on setting speed limits.

20 mph speed limits and zones

We have the power to install 20 mph speed limits or zones on:

  • residential streets in towns and villages where there is community support and the characteristics of the street are suitable
  • on other town streets which have a lot of pedestrian and cyclist movement (on major streets, the need for the limit should outweigh the disadvantage of the resultant longer journey times for traffic)

20 mph limits/zones should not require any enforcement by the police to keep speeds within the limit.

There are 2 ways to create 20 mph roads:

  • a 20mph traffic calmed zone
  • a signed 20mph speed limit

20 mph zones require traffic calming measures (e.g. speed humps, chicanes) or repeater speed limit signing and/or roundel road markings at regular intervals, so that no point within a zone is more than 50m from such a feature. They also:

  • require the beginning and end of a zone is indicated by special 20 mph zone entry and exit signs
  • usually cover a number of adjacent roads e.g. a residential estate
  • should not include roads where motor vehicle movement is the primary function


Safety cameras

Fixed safety cameras

TVP are in the process of upgrading a number of safety camera housing to enable digital technology. However, our preference is for consideration to be given to alternative speed reduction measures, road layout changes and signing/ lining modifications in order to reduce speed related collisions.

As a result there are currently no plans to introduce additional fixed safety (speed) camera housings in Buckinghamshire.

Mobile safety cameras

Requests for mobile speed enforcement should be made via the Police Neighbourhood Team
