Operation payload management investigated the impact of two weighing technologies (truck and loader installed scales), operated by hired drivers and owner-operators on two route types; gazetted (classified for increased GVW limits) and non- gazetted (standard GVW limits for public roads). On non-gazetted roads the two approaches proved equally effective but when used together appeared to be less effective, while the owner operators appeared to have better management of the payload compared to hired drivers. On the gazetted roads all vehicles were under loaded by roughly the extra payload amount offered by the gazetted routes, which highlights the importance of communication and overall management to ensure payload potential is realised.
