Viterra continuously works 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 grain from farm to site.
Carriers and their drivers should be familiar with the South Australia Heavy Vehicle Farm Gate Grain Transport Mass Exemption Notice 2020 (No.1) and the Heavy Vehicle National Law.
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.
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 the general mass are required to provide evidence of entitlement such as their accreditation number under the National Heavy Vehicle Accreditation Scheme (NHVAS) and permit number issued by the NHVR.
Failure to provide evidence of mass limit entitlement will result in the vehicle being treated as operating at the general mass limit.
Please contact the NHVR on 1300 696 487 or nhvr.gov.au if you require more information.
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 extend, the Weighnote will be marked with a mass breach warning and the information may be passed onto the NHVR.
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 be mindful of the maximum mass limit allowed on all roads used during the entire journey, including the ‘last mile’.
The road 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 route assessment. To find out more information please see the NHVR route planner or RAVNet maps.
