Three-axle bus mass limits review


This project identified that there is a need to increase the mass limits that apply to three-axle buses and assessed the potential implications.


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 be eligible for this increase, there are additional safety requirements to be met, which are set out in the NTC Decision Regulation Impact Statement.
