NHVR Routing: Calculate Routes That Stay on Approved Roads
Truck Me uses live NHVR data to calculate routes that only use roads approved for your vehicle class. B-Double, Road Train, PBS. Select your truck and the routing engine handles compliance.
NHVR routing vs standard GPS routing
A standard GPS app, Google Maps or Apple Maps, picks the fastest route for a car. It has no concept of heavy vehicle access codes, network designations, or per-class approvals. Sending a road train down a car-optimised route is how drivers end up on restricted roads, facing fines, and looking for a turnaround point.
NHVR routing means the route algorithm is constrained from the start. The NHVR network for your vehicle class defines which roads are available as route candidates. The algorithm picks the best path through that constrained set. Every turn-by-turn instruction only uses approved roads.
This is not a filter applied after the route is calculated. It is built into the calculation itself. The router never proposes a road and then checks it. It only proposes roads that are already in the approved set.
Vehicle combination types and why they matter
The NHVR uses vehicle combination types to define which network applies. Getting the vehicle type right is the first step in getting the route right.
B-Double
Two trailers, up to 26 metres. Approved on the B-Double Network. Cannot use general access heavy vehicle roads that are not on the B-Double designation.
Road Train
Three or more trailers, up to 53.5 metres. Restricted to the Road Train Network. The tightest network of the three, largely covering outback freight routes.
PBS Vehicle
Performance Based Standards vehicles are assessed individually. Approval is tied to the specific vehicle configuration and the route must be verified against PBS segment data.
General Access Heavy Vehicle
Vehicles operating within standard mass and dimension limits under the National Network. Broadest access, but still subject to bridge limits and local conditions.
The route calculation process
Select your vehicle
Choose from saved vehicle profiles or enter your combination type. Truck Me identifies the corresponding NHVR network.
Enter your destination
Type or select your endpoint. Origin defaults to current GPS location or can be set manually for pre-trip planning.
Network check
The routing engine queries NHVR network data for every road segment on the candidate route. Restricted and non-network segments are excluded.
Dual-route calculation
The approved route and an unrestricted comparison route are calculated in parallel. Both appear on screen with distance and estimated time.
Turn-by-turn navigation
Select a route and start navigating. Community incident markers are overlaid in real time. The map shows the NHVR network overlay throughout the trip.
Route intelligence
Approved routes are not always the most efficient routes. The NHVR network sometimes forces significant detours around segments where approval has not been granted. Drivers taking those routes have no way of knowing whether a shorter path exists or whether the detour is genuinely necessary.
Truck Me runs two calculations for every route: the NHVR-approved route and the fastest unrestricted route. Both are displayed side by side with distance and estimated travel time. If the approved route is significantly longer, the app shows which specific segments are responsible for the difference.
This gives drivers clear information about the trade-off. It also surfaces cases where the approved network may be suboptimal, data that Truck Me aggregates for community route quality reporting.
Dual-route example
Brisbane to Toowoomba: approved B-Double route via Warrego Highway is 135 km. Unrestricted fastest route is 128 km via a corridor not on the B-Double network. Truck Me shows both, flags the difference, and routes you compliantly. The 7 km detour becomes a visible, explained choice, not an invisible surprise.
Alternative routes that stay on the network
When a community-reported incident sits on your route, Truck Me offers a reroute. The alternative is not just the next fastest road. It is the next fastest road that is approved for your vehicle class.
The same applies to the fastest vs shortest comparison. Truck Me surfaces alternative approved routes, not just one. A longer route through a well-maintained approved corridor may be faster in practice than a shorter approved route through congested sections.
All alternatives are checked against the NHVR network before being offered. You never see a route option that would take you off the approved network.
Community intelligence on top of network data
The NHVR network tells you which roads are legally approved. It does not tell you that there is a road closure 40 km ahead, a flooded crossing on your planned route, or roadworks that have reduced a two-lane section to one-way. That information comes from drivers.
Truck Me has a community incident reporting system built into the app. Drivers report incidents with two taps. Reports are GPS-pinned to the map and visible to other drivers in real time. Incidents on your active route trigger a notification and a reroute offer.
Incidents auto-expire based on type. A breakdown clears after 4 hours by default. Roadworks stay active for 7 days. Other drivers can confirm an incident is still present or mark it cleared. The map stays current without any central moderation.
Incident types include accidents, road closures, flooding, debris, police checks, roadworks, and general hazards. All are tied to real GPS coordinates and visible on the approved network map.
Core routing features
Vehicle class selection
Select your vehicle type once and the routing engine works from the correct NHVR network. Switch vehicles and the map updates instantly.
NHVR-constrained routing engine
Every segment of every route is checked against the NHVR network for your vehicle class before it appears in your directions.
Dual-route comparison
See the approved route and the unrestricted fastest route side by side. Know upfront if the approved route adds significant time and why.
On-network incident avoidance
If an incident blocks your route, one tap reroutes you. The alternative stays on approved roads, not just the fastest available road.
