Three-axle bus mass limits review

This project will identify whether there is a need to increase the mass limits that apply to three-axle buses and assess the potential implications.
For some time, there has been a mismatch between regulatory provisions for determining bus occupancy numbers and those setting maximum axle mass limits. Bus mass has increased for several reasons, including the increased average weight of the Australian population over recent years and the increased tare weight of buses as a result of regulatory requirements for specific safety and environmental improvements.
In November 2018, transport ministers approved a gross mass limit increase for three-axle buses from 20 tonnes to 22 tonnes.
The increase will take effect once the Heavy Vehicle (Mass, Dimension and Loading) National Regulation is amended, which is expected to be in 2019. To access this increase, there are additional safety requirements to be met, which are set out in the NTC Decision Regulation Impact Statement.
