Truck Scale Operator Checklist to Support Compliance

Truck Scale Operator Checklist

Supporting Chain of Responsibility Compliance

Checking the load on the truck scale is an important step before transportation to ensure compliance with road safety laws and the Chain of Responsibility. This Truck Scale Operator Checklist helps the operator to perform the steps required to determine the correct weight of goods being transported, which ensures the vehicle is not overloaded. 


Chain of Responsibility

According to the National Heavy Vehicle Regulator (NHVR), the Chain of Responsibility recognises that everyone in the supply chain is responsible for ensuring heavy vehicle safety, with a large focus on risk management processes. These changes were enforced as of October 2018.

Checking a Truck Scale

The operator must ensure the weighbridge is correctly run and should flag any issues to the truck scale supplier or technician.

The operator should:

  • Visually inspect the truck scale to ensure it is in good condition at the start of each shift
  • Perform regular checks for weighbridge accuracy
  • Monitor truck scale performance

Determining Truck Load Net Weight Basic Weighing Procedure

  1. Inform driver to slowly approach the weighbridge and drive onto the platform
  2. Once vehicle is completely on platform, ensure no other surfaces are in contact for accurate results
  3. Instruct driver and passengers to dismount vehicle and platform for consistent weight. (When vehicle returns, driver might be different or not carrying the same passengers) (This is the appropriate procedure for trade transactions, however this is not always possible as the driver may be required to remain seated for law enforcement officers.)
  4. Weigh the vehicle (loaded or unloaded). Record the gross (or tare) mass on the measurement ticket once weighing is completed
  5. Once the vehicle returns, weigh the vehicle (loaded or unloaded). Ensure the tare (or gross) mass is on the measurement ticket as soon as the weighing is completed

To obtain the net mass, subtract the tare mass from the gross mass. Record the net mass on the measurement ticket.

Offences and Penalties

Failing to comply with the law may result in a financial penalty for the truck scale operator and the business.

Common offences include using a truck scale:

  • Which is not verified
  • Which is not accurate
  • In an unjust manner, e.g. not starting on zero when measuring weight
  • To weigh a mass greater than the maximum capacity of the weighbridge (in a single measurement)
  • When the approaches are unsuitable

Trade Measurement Inspectors

Trade Measurement Inspectors regularly audit trade approved weighbridges to ensure that tickets for weighing and measurement comply with legislation.

If a trade approved truck scale is inaccurate or does not meet legislation, the inspector will issue a notice to suspend it. The truck scale will require repair, recalibration, re-testing and re-verification.

Trade measurement inspectors have authority to enter your property to inspect business vehicles and to search and seize items. This includes copying documents, recording information and testing measuring instruments.
