Type Approval

Type Approval


Type approval is the process by which certain road enforcement equipment is approved by the Home Office for use by police forces (or safety camera partnerships), in order to record data which is admissible as evidence in prosecutions relating to speed, red traffic lights and drink and drug driving. It is a well established and rigorous process.

The process consists of two main phases:

  • Phase 1 – Police force trials of the equipment organised through the Association of Police Chief Officers (ACPO).

  • Phase 2 – Laboratory tests of the equipment organised through (though not necessarily undertaken by) the Home Office’s Centre for Applied Sciences and Technology (CAST).

Phase 1 trials allow for an initial assessment to be made on the equipment’s suitability with regards to operational performance, without the financial and time costs associated with the more in depth laboratory tests

Once an assessment has been carried out and the manufacturer advised on the operational suitability, phase 2 tests then run the equipment through more in depth assessments such as environmental operating limits, accuracy of results, and data integrity. These tests are defined by the Home Office, are rigorous and are standardised for all similar devices.

Results and feedback from both of these phases are then used to make a final decision on the approval of the equipment.

Once the decision is made to grant approval, a formal agreement is drawn up with the manufacturer requiring them not to modify the device in any way without prior consent.

Final sign off must be obtained by the Secretary of State at which point UK police forces are informed of the new type approval.
