Viterra is working with the grain industry, the National Heavy Vehicle Regulator (NHVR) and SA Police to implement measures that reduce heavy vehicle overloading and promote compliance with transport regulation, while still recognising the difficulties faced by growers and heavy vehicle operators in moving the crop from farm to site.
Carriers and their drivers should be familiar with the South Australian Grain Carriers Code of Practice which is registered with the NHVR.
The code does not provide authority for any vehicle to be loaded in excess of its statutory mass limit. Growers, loaders and drivers all have their own obligations under transport regulation. If you are unsure of your obligations you should seek independent advice.
Anyone driving a vehicle carrying grain must ensure they are aware of and comply with all Chain of Responsibility requirements, including heavy vehicle mass management.
The driver is responsible for determining the vehicle’s legal mass limit and is required to declare the legal mass of their vehicle at a Viterra site.
Drivers are required to declare the mass of their vehicle via the Mass Limit Code. This code is linked to the legal mass of the specific vehicle configuration, including accredited vehicles. The Mass Limit Code is recorded on the weighnote.
Declaring the wrong code on a weighnote or exceeding the legal gross vehicle mass limit constitutes an offence that may be dealt with by the NHVR.
Drivers claiming vehicle mass limits higher than general mass are required to provide evidence of entitlement.
All vehicles claiming a Higher Mass Limit (HML) or Concessional Mass Limit (CML), which include mass codes starting with the letters C, H or GH, must:
All vehicles claiming a Permit-based Mass Limit, with a mass code starting with P, must provide the permit number. Failure to provide supporting evidence of the mass limit entitlement, via either NHVAS accreditation or permit, will result in the vehicle being treated as operating at the General Mass Limit.
Please contact the National Heavy Vehicle Regulator on 1300 696 487 if you require more information on the accreditation and permit schemes.
When a vehicle is loaded, the loader and driver have a responsibility to ensure the vehicle is not loaded in excess of its permitted mass limit.
Viterra weighs vehicles on entry and exit of its facilities. If a vehicle enters any Viterra site overloaded to any extent, the Weighnote will be marked with a mass breach warning.
Viterra employees will advise drivers of overloaded vehicles of any requirements to ensure site safety and safe management of the vehicle.
If the vehicle is loaded on farm, both the loader and driver are required to demonstrate that corrective actions have been taken to avoid overloads recurring.
If breaches are committed, the grower who consigned the load may also receive a formal letter, phone call or email from Viterra advising of the breach, in accordance with Chain of Responsibility legislation.
Carriers and drivers need to consider the maximum mass limit allowed on all roads used during the entire journey, including the ‘last mile’.
The roads immediately adjacent to grain receival sites may be subject to lower restrictions on vehicle mass, which is commonly referred to as the ‘last mile’.
Carriers and drivers must take into consideration these ‘last mile’ restrictions when planning off-farm deliveries to Viterra sites as part of their pre-load route assessment. See the journey planner available here.
