BTS21: Weigh your on-board mass options

Smart OBM systems are here, so make sure you know what you need


Smart OBM systems are digitally connected on-board weighing systems that enable new productivity and safety initiatives using applications of the National Telematics Framework (NTF).

Smart OBM systems use digital technology to collect and transmit mass data from vehicles in a reliable and standardised way.

There are different categories of OBM system, but only Category B or C can generate and transmit data for use with applications of the NTF.

Although Category A OBM systems have been type-approved by TCA for accuracy and integrity, they do not offer data generation and transmission capabilities.


On-board mass measurement can be very valuable for supporting your commercial operations. OBM systems provide you with critical information about the loading of your vehicles, which is important to manage safety and regulatory compliance while also maximising productivity.

Smart OBM systems allow the digital collection and transmission of data for later analysis and reporting – these smart systems are in use for a range of road access schemes, permits and national notices across jurisdictions. 

You will need a Smart OBM system if required by a road manager, regulator or other party that specifies it as a requirement.

These road access conditions include all high productivity freight vehicles in Victoria and performance-based standards vehicle combinations in Tasmania. There are also a number of new permit arrangements in New South Wales and Queensland.

If you are a transport operator, make sure you ask for a Smart OBM system if you want to benefit from new productivity and safety reforms.
