Cleveland and Durham Specialist Operations Unit


The CDSOU includes various teams and departments, and consists of officers and staff from Durham Constabulary and Cleveland Police.

This page features details about some of the teams.


Collision Investigation Unit

The Collision Investigation Unit comprises officers from the Cleveland and Durham Constabularies, based at the Road Policing Unit (RPU) in Wynyard, on the Durham-Cleveland police border.


The unit consists of experienced officers with either a roads policing or an investigative background.




The unit investigates all fatal collisions/accidents on the roads of County Durham, Darlington and Cleveland and attends serious and life-threatening collisions/accidents, offering assistance and expertise to officers in the RPU.











Their role includes:


  • a scale survey of the scene
  • detailed vehicle examinations
  • marks at scene and how they were generated e.g. tyre marks
  • assessment of damage to vehicles
  • dynamics of collision
  • sight lines (the maximum view drivers could see on approach, dependent on other vehicles and activity)
  • conclusion
  • file preparation


As well as road collisions/accidents they are able to assist CID with serious crime scene surveys and the Health and Safety Executive with serious and fatal industrial accidents.

If you have a query in relation to an accident which occurred in the Durham or Darlington area that is not about a fatal or life threatening accident then please contact central accident records. (link to Central Accident Records page under Know the Law section)


Safety camera unit and speed enforcement 

Excess speed is one of the major causes of road casualties and speed enforcement is an essential tool of any casualty reduction strategy.

As part of a casualty reduction  strategy, specific locations and stretches of road which generate the highest level of casualties have been identified where speed enforcement using the mobile safety camera unit can be carried out.



The areas where the safety camera is currently being deployed in support of the speed enforcement strategy are:

      ·         A690 West Rainton

      ·         A67 High Coniscliffe, Darlington

      ·         A67 Darlington Road, Barnard Castle

      ·         A693 Blind Lane, Chester le Street

      ·         B6532 Edmondsley Lane, Daisy Hill, Sacriston

      ·         A68 Rowley Bank, Castleside

      ·         A692 Consett Road/Deneburn Terrace, The Grove, Consett

      ·         A692 Dipton

      ·         A167 Aycliffe Village

      ·         Orbital Road, Chester le Street

      ·         Lowhills Road/York Road, Peterlee

      ·         A6076 Shield Row Bank

      ·         B6168 Annfield Plain/Catchgate

      ·         B6409 Watling Street, Leadgate

      ·         B1283 Sherburn West

      ·         Carmel Road South/Ayton Drive, Darlington


As well as the above locations the camera van can be deployed at specific sites if they  have been subject of local complaints and traffic data analysis supports the deployment of the van.. The use of the camera is always subject to a risk assessment to ensure it is safe to use in the location being considered.


Some offenders caught speeding by the safety camera  may be offered the option to take part in the 'Speed Awareness Diversionary Scheme'.

This gives drivers the option of avoiding formal court action by attending a course which highlights and educates drivers about the dangers of excess speed. 

As well as the safety camera unit RPU officers carry out speed enforcement and a range of other enforcement checks together with driver education options in an effort to reduce road casualties.



At the present time if you are stopped for a speeding offence by an RPU officer, you will not be offered the option to attend a speed awareness course as an alternative to prosecution.
