Abstract
A system 10 for monitoring the load on a load carrying vehicle comprises an electronic radio frequency (RF) identification system 22 comprising a reader 24 and a plurality of RF transponders 28.1 to 28.n. Each transponder is associated with a respective load item 36.1 to 36.n, and the items collectively constitute the load located in a load carrying region of the vehicle. The reader is operative in use to interrogate the transponders, to read response data received from the transponders and to generate data relating to a load change event. A controller 34 and a vehicle position data generating device 38 are connected to the controller. The controller is sensitive to a load change event and operative to record vehicle position related data corresponding to the load change event.
