Important points for drivers at the sites

Anyone delivering to a site should note the following points:

Uncontrolled vehicle movements

Recent harvests have seen an increasing number of vehicles moving without anyone in control of the vehicle. In order to protect the safety of all personnel associated with our operation it is a requirement that:

  • vehicles accessing Viterra sites be adequately maintained ensuring that all brakes be in good working order
  • park brake alarms, where installed, be used
  • park brakes be applied at all times prior to leaving the vehicle cabin.
If you require disengagement of brakes for the purposes of discharging your load (for example tip over axle vehicles) you will be required to implement a safe system of work to the satisfaction of Viterra staff. Please contact your local Viterra site to discuss this prior to harvest.

After reviewing any incident of an uncontrolled vehicle movement, Viterra may take appropriate and necessary action. This may include requiring evidence of certification, roadworthiness and denying access to sites if a vehicle is deemed to be unsafe.

Tipping in bunkers (where available)

  • Always reverse in when entering a bunker.
  • When tipping/backing into bunkers, chains on tailgates should be completely removed to assist stockpiling grain into the one heap.
  • Trucks should not turn around on the bunker but move off slowly, directly out.
  • Extra care needs to be taken in wet conditions.

Employees on site are there to direct and guide drivers to ensure that everything is done in a safe and efficient way. This helps ensure we can maximise the number of trucks moving around the site.

Drive over hoppers – chains on tailgates

To efficiently run the drive over hoppers and reduce turnaround times, we ask that drivers have chains on tailgates set at a 100mm gap.

This gap ensures grain goes directly onto the underbelly belt on the hopper, helping to maximise its performance. It also reduces spillage around the chassis, rims and concrete so there is less time cleaning erquired, making it a safer task for drivers and Viterra employees.

Heavy Vehicle Mass Management

Viterra 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 the crop from farm to site.

Growers and carriers should be familiar with the South Australian Grain Carriers Code of Practice which is registered with the NHVR.

A copy of the code can be accessed online via the South Australian Road Transport Association (SARTA) website.

The code does not permit any vehicle to be loaded in excess of its statutory mass. Growers (as consigners of freight), loaders and drivers all have their own obligations under transport regulation.  If you are unsure of your obligations you should seek independent advice.

Growers and their carriers delivering to sites in either Victoria or New South Wales should refer to information regarding east coast heavy vehicle mass management.

Driver Declaration of Legal Mass

The driver is responsible for determining the vehicle’s legal mass limit and is required to decalre 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 specific vehicle configurations, 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.  Should you require more information on the accreditation and permit schemes please contact the National Heavy Vehicle Regulator on 1300 696 487.

Operation of vehicles at Higher Mass Limits or by Permit

All vehicles claiming Higher Mass Limit (HML) or Concessional Mass Limit (CML) must be accredited under the National Heavy Vehicle Accreditation Scheme (NHVAS), display the accreditation label on the vehicle and comply with the South Australian Heavy Vehicle Farm Gate Grain Transport  Exemption (Notice) 2015.

All vehicles claiming a Permit-based Mass Limit, with a mass codes starting with P,  must provide the permit number.

Failure to provide supporting evidence of the vehicle’s mass limit entitlement, via either NHVAS accreditation or permit, will result in the treatment of the vehicle as operating at the General Mass Limit.

The required NHVAS accreditation label number is highlighted below.

Management of overloaded vehicles

When a vehicle is loaded, the loader and driver have a responsibility to ensure the vehicle is not loadedin excess of its permitted mass limit.

Viterra weighs vehicles on entry and exit of its facilities.If a vehicle enters a Viterra site overloadeded 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 andsafe management of the vehicle.

If the vehicle is loaded on farm, both the loader and driver are required to demonstrate that corrective actions are being 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.

Breaches include:

  • Entering any Viterra site with a vehicle that exceeds its Statutory Mass Limit.
  • The driver being unable to demonstrate corrective actions have been taken to manage mass inaccordance with the Code (i.e. overload percentage trending downwards).
  • The driver being unable to provide the required information about the vehicle (e.g. if the incorrectlegal mass is declared by the driver, incorrect accreditation label numbers or truck registration details).

Site access restrictions - the 'last mile'

  • 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 should take into consideration these 'last mile' restrictions when planning off-farm deliveries to Viterra sites as part of their pre-load route assessment.

List of Site Access Restrictions for the 2016/17 harvest.

Please note - this list is not exhaustive and is provided for reference by carriers and drivers when planning grower deliveries. Carriers and drivers retain responsibility for the correct judgement of permitted maximum vehicle mass for the whole route prior to commencement of their journey. Carriers and drivers are encouraged to utilise the NHVR's Journey planner and the RavNet system maintained by the South Australian Department of Planning, Transport and Infrastructure (DPTI) which publishes road permissions within South Australia. Where inconsistencies occur, DPTI's RavNet is the presiding authority for restricted access vehicles. DPTI's RavNet is available at ravnet and the NHVR's Journey Planner is available at
