Performance Based Standards (PBS)
More about the PBS Scheme in Australia
The Australian Design Rules and Heavy Vehicle National Law govern the size and mass of heavy vehicle combinations permitted on Australian roads.
They are prescriptive, out-of-date and limit what heavy vehicles can carry – whether that’s by volume or by mass limitations on bridges.
PBS was incorporated into the law, to recognise that times have changed and we can now simulate vehicles and determine if they’re safer and more productive. Instead of fixed size and mass restrictions, PBS assesses your vehicle combination against 16 performance-based safety and infrastructure standards.
This opens the door to optimized designs and for existing vehicles to be assessed and certified. Through certification, you can unlock your fleet’s performance and productivity, all while ensuring the highest safety standards remain in place.

Unlocking Productivity with PBS Certification
PBS offers a smarter approach, recognizing advancements in vehicle technology and simulation. It allows flexibility to go outside some dimensional limits, unlocking greater productivity. More productive means they can cart more payload, safer, more efficiently and with fewer movements.
This flexibility translates to significant benefits:
- Increased payload: Haul more per trip, reducing truck movements and emissions.
- Enhanced efficiency: Improve fuel economy and operational costs through optimized weight distribution and lower tare mass.
- Greater Access: Utilize more productive vehicles on approved road networks, including:
- Truck and Dog combinations (3-axle truck & 4-axle dog) reaching up to 57.5t GCM on the Level 2 Network.
- A-double vehicles reaching up to 85t GCM on permitted B-double routes.
- 20m Semi-trailers gaining general access.
- Spread axle trailer combinations achieving higher GCM with lower tare masses.
By embracing PBS, you can unlock the hidden potential of your existing fleet, optimize your operations, and stay ahead in the evolving transport landscape.
