A system for encouraging the use of a load stabilizer in a cargo carrying vehicle comprising a storage device which has a detector, the detector being adapted to sense the presence or absence of a stabilizing member such as a shoring bar, the detector being designed to emit a first signal upon sensing the presence of the stabilizing member and to emit a second signal upon sensing the absence of the stabilizing member. The signal could activate or trigger a visual or audio indicator or alternatively the signal will allow or prevent an action being taken.
