This page contains links to the current calibration certificates for speed and red light cameras used by the Safer Roads Partnership in West Mercia.

Calibration verifies the camera equipment so that the process meets requirements. Speed enforcement cameras are calibrated so that only vehicles travelling above the speed limit are seen and photographed by the camera.

Please note, the certificates below relate to the physical camera in the housing and not the camera housing or the mobile site itself.

Expired certificates will be moved to the ‘Archived’ section below.
