PBS Vehicle Routing Australia: Plan Routes for Performance Based Standards Vehicles
Performance Based Standards vehicles operate on their own NHVR-approved network. It is not the same as the B-Double or Road Train network. Truck Me routes PBS vehicles on the correct approved corridors for their specific PBS class.
What Performance Based Standards vehicles are
The PBS scheme is a national framework managed by the NHVR that allows heavy vehicles to be approved based on how they perform rather than on fixed dimension and mass limits. Under the standard prescriptive rules, a B-Double must be no longer than 25 metres and no heavier than 62.5 tonnes gross. PBS removes those fixed limits if the vehicle can demonstrate it meets defined performance standards.
Those performance standards cover four areas: safety (braking distance, rollover threshold, rearward amplification), geometry (swept path on turns, tail swing), pavement damage (the load the vehicle puts on the road surface), and infrastructure compatibility (bridge loading). A vehicle that passes all relevant standards for its PBS level gets an NHVR approval and access to the approved network for that level.
The result is that PBS vehicles can be significantly larger and heavier than standard combinations while still being legally compliant. They are common in grain transport, livestock, and bulk commodity haulage where productivity per kilometre is a significant operating cost factor.
The trade-off is network access. A standard B-Double can use any road on the B-Double network. A PBS Level 3 vehicle is limited to corridors specifically approved for PBS Level 3. The approved network is narrower for higher PBS levels.
PBS approval levels
Each PBS level has its own approved network. Select the correct level when creating your vehicle profile in Truck Me.
PBS Level 1
Entry-level PBS class. Comparable in dimensions to standard B-Double combinations but assessed under the PBS performance standards framework. Widest network access of the PBS classes.
PBS Level 2
Larger combinations with higher productivity than Level 1. Approved on a narrower set of corridors assessed as capable of handling the increased mass and length.
PBS Level 3 and 4
The highest PBS classes, covering very long and very heavy combinations. Network access is the most restricted and is typically limited to specific high-productivity freight corridors.
Why the PBS network is separate from B-Double and Road Train networks
The NHVR assesses each road network independently for each vehicle class. A road on the B-Double network has been assessed for B-Double combinations. It has not necessarily been assessed for a PBS Level 2 vehicle, which may be longer, heavier, or have different swept path characteristics at intersections.
Road managers, which can be local councils, state road authorities, or the NHVR itself, apply to have roads assessed for each class. A road manager who has sought B-Double approval for a road may not have sought PBS approval for the same road. The result is that the PBS network has gaps that the B-Double network does not have, and also corridors that are specifically approved for high-productivity PBS vehicles where standard combinations are not the primary use case.
Using a routing app that does not distinguish between PBS levels and standard networks means you are at risk of being routed onto roads that are not approved for your vehicle. The NHVR access codes are vehicle-class specific. A general heavy vehicle GPS does not have this data.
Built for PBS vehicle operators
Every feature accounts for the specific network requirements of PBS vehicles.
PBS vehicle profile support
Create a vehicle profile matching your PBS approval level. Truck Me routes on the correct NHVR network for that specific PBS class, not the generic heavy vehicle network.
PBS network overlay
Green, amber, and red colour coding on every road segment specific to your PBS vehicle class. See approved, conditional, and restricted roads at a glance before you plan.
Segment-level condition display
PBS conditional segments carry specific conditions: mass limits, speed restrictions, escort requirements. Truck Me shows these before routing you onto the segment.
Approval reference in profile
Store your PBS approval reference in your vehicle profile. Useful when you are stopped at a check and need to reference your vehicle class and approval status quickly.
Network change notifications
Truck Me monitors the NHVR PBS network for your saved routes. If a segment changes access status, you get a push notification before your next trip.
Route intelligence comparison
See both the PBS-approved route and the unrestricted route side by side. Know before you leave whether the approved route adds significant time or distance.
Frequently Asked Questions
What is a PBS vehicle?
A Performance Based Standards vehicle is a heavy vehicle combination approved under the PBS scheme rather than under standard prescriptive dimension and mass limits. PBS vehicles are assessed against performance outcomes: how well they brake, turn, track, and handle rollover risk. If the vehicle meets those performance standards, it can exceed standard dimension or mass limits. The NHVR administers the PBS scheme nationally.
Is a PBS vehicle the same as an overdimension or oversize load?
No. PBS vehicles are a distinct category. An overdimension load is a specific load that exceeds standard limits and requires a movement permit for each trip. A PBS vehicle is a vehicle that has been permanently approved under the PBS scheme and can operate on its approved network without a per-trip permit. The approved network for a PBS vehicle is managed by the NHVR through the same system as other heavy vehicle networks.
Why does PBS routing need to be different from standard B-Double routing?
The NHVR maintains separate approved networks for each vehicle class. The PBS Level 2 network is not the same as the B-Double network. Roads are assessed separately for each class based on the performance characteristics of that vehicle type. A road on the B-Double network may not be on the PBS Level 2 network, and vice versa. Using the wrong network means planning routes that may be non-compliant.
How does Truck Me handle PBS vehicle profiles?
When you create a vehicle profile in Truck Me and select a PBS level, the app retrieves the NHVR network data for that PBS class and uses it to calculate routes, colour-code the map overlay, and check segment conditions. You do not need to manually identify which roads are approved for your class.
Can I check PBS network access for a specific road segment?
Yes. Tap any segment on the Truck Me map to see its access status and conditions for your current vehicle profile. This works from the depot before you depart, not just while navigating.
Does Truck Me cover PBS vehicles in all states?
The NHVR PBS network data covers all states and territories where NHVR jurisdiction applies. Truck Me reads this data directly from the NHVR API for your vehicle class.
