We are investigating ways to streamline the approval process for seven-axle truck and trailer combinations to improve productivity.

Purpose

Increasing the number of higher productivity vehicles using the network will help Australia’s economy grow by boosting the productivity of our transport system.

Performance based standards (PBS)-approved vehicles can carry heavier loads and can offer up to 20 per cent more productivity than non-PBS vehicle combinations, but industry has said that the time and cost taken to approve PBS design, assessment and certification act as barriers to greater use.

The PBS scheme aims to encourage the uptake of more productive vehicle designs without sacrificing safety requirements.

Next steps

National Heavy Vehicle Regulator (NHVR) is developing a Class 3 National Notice as an interim measure to allow access to networks.

The NTC will review the effectiveness of the Class 3 National Notice after three years with a view to allow compliant seven-axle truck and trailer combinations through regulation.

Background

We have gained agreement from state and territory governments for the National Heavy Vehicle Regulator (NHVR) to streamline the approval process for seven-axle truck and trailer combinations that meet PBS.

The NTC has developed a specification envelope for seven-axle truck and trailer vehicle combinations. The envelope provides ‘boundary conditions’ (i.e. the dimensional range within which PBS vehicles are currently built). PBS vehicles constructed in accordance with the specification envelope that can be used to carry heavier loads than conventional seven axle combinations. The designs are for:

  • seven-axle truck and trailer with low bins
  • seven-axle truck and trailer with high bins.

Seven-axle truck and trailer combinations that fit within the specification envelope will be permitted to be operated up to PBS mass limits on the networks specified by the relevant road managers.
