If the equipment wasn't properly calibrated and approved, the evidence against you may be unreliable.
Every speed detection device used by UK police forces - from fixed Gatso cameras to mobile laser guns (LTI 20/20, ProLaser) - must hold a current Home Office Type Approval certificate and be calibrated in accordance with the manufacturer's specifications. Appeal Specialists demands disclosure of these records in every case.
If the prosecuting authority cannot produce evidence that the specific device used to record your alleged speed was properly approved, calibrated, and operated at the time of the offence, the reliability of the evidence is undermined.
Every speed detection device must be of a type approved by the Secretary of State. We request the Type Approval certificate for the specific make and model of device used, verifying it covers the mode of operation employed (e.g., static vs. mobile deployment).
We request the most recent calibration certificate for the specific device (identified by serial number). Calibration must have been carried out within the manufacturer's prescribed intervals. Expired or missing calibration records cast doubt on the accuracy of the speed reading.
Regular maintenance is essential to ensure reliable readings. We request the full service history of the device, looking for any recorded faults, repairs, or periods where the device was out of service or returned to the manufacturer.
Mobile speed detection devices must be operated by trained and qualified officers. We examine whether the operating officer held a current qualification for the specific device used, and whether the device was deployed in accordance with approved operating procedures.
