Queensland low-loader operators can now test the National Automated Access System ahead of a November rollout that will begin shifting eligible Class 1 heavy vehicles away from traditional permit-based access.
The Queensland Government has opened a four-week preview of the National Automated Access System (NAAS), giving low-loader operators an opportunity to build vehicle libraries, test routes and familiarise themselves with the system before its full introduction later this year.
The preview runs from 24 August to 18 September 2026.
Importantly, it is not yet a live access system. No access approvals generated during the preview can be used for a journey, and operators must continue using their existing access arrangements, including permits where required.
The Department of Transport and Main Roads says network decisions displayed during the preview are based on data uploaded from November 2025. Current network data will be used when the system goes live.
Try the NAAS preview now
Queensland low-loader operators can access the NAAS preview online and start familiarising themselves with the system ahead of the planned November rollout.
Operators can enter their low-loader combinations, build a vehicle library and explore how NAAS displays available routes and access conditions for different vehicle configurations.
The preview does not provide legal access approval. Operators must continue to use their existing access arrangements, including permits where required, during the preview period.
The preview runs until 18 September 2026.
Access the NAAS preview and TMR operator guidance
What changes in November?
Queensland plans to fully adopt NAAS for eligible low-loader vehicles in November 2026.
NAAS will become the default road-access pathway for eligible low loaders operating outside the National Class 1 Load Carrying Vehicle Dimension Exemption Notice 2025 (No. 2) and National Class 1 Load Carrying Vehicle Mass Exemption Notice 2025 (No. 1).
Instead of relying on a conventional permit assessment for many movements, operators will enter their vehicle configuration, dimensions and mass into the system.
NAAS assesses that vehicle against available road and structural information and generates a vehicle-specific access map showing where it can travel and the conditions applying to the journey.
Those conditions can include mass and dimension restrictions, bridge conditions, pilot and escort requirements, curfews and road closures.
Where suitable access cannot be obtained through NAAS, operators may still need to apply for an NHVR permit.
TMR says it expects most period-permit vehicles and some vehicles currently operating under single-trip permits to transition to access through NAAS.
What operators can do now
During the preview, operators can create their low-loader vehicle combinations and build a library of vehicle codes.
That means operators have an opportunity to test the system against the vehicles they actually operate before November.
TMR is encouraging operators to do exactly that.
The department is also conducting industry support sessions around Queensland during the preview period.
The preview may therefore be particularly useful for operators to identify discrepancies or practical problems before access decisions become operational.
Existing permits aren’t simply disappearing
The transition is more complicated than switching one system off and another on.
Existing low-loader permits will not automatically become invalid when NAAS launches.
TMR says existing permits will be reviewed to determine whether the vehicle can instead operate under the new NAAS notice or whether updated conditions need to be incorporated into the permit.
The department has also begun shortening the duration of newly issued and renewed low-loader permits as the November implementation approaches.
Permits approved between 24 August and 30 September may be issued for up to nine months, while those approved between 1 October and 15 November may be issued for up to six months.
Existing permits are not affected by those transitional duration changes.
From permits to automated access
NAAS represents a significant change in the way heavy-vehicle access decisions are made.
Rather than applying a single set of limits across the network, the system is designed to assess access according to the characteristics of an individual vehicle and the capacity of roads and structures.
Queensland’s existing Conditions of Operation Database is eventually expected to be deactivated, with Class 1 access conditions instead provided through NAAS or individual permits.
TMR also says its Vehicle Limits Manual will ultimately cease to apply under the new approach.
The longer-term national ambition is considerably larger than Queensland’s low-loader rollout.
Australian transport ministers agreed to develop a National Automated Access System aimed at reducing heavy-vehicle permit requirements by 50 per cent within three years and 90 per cent within five years.
Queensland is starting with low loaders.
Mobile cranes are scheduled to follow in 2027, while platform trailers and Performance Based Standards vehicles are currently scheduled for implementation in 2028.
For Queensland low-loader operators, however, the change has already begun.
The preview provides the first opportunity to see how vehicles, routes and restrictions appear inside the system before those automated access decisions start carrying real operational consequences in November.
WWTG quick take
What happened? Queensland opened its NAAS preview for low-loader operators on 24 August.
Can operators use it for access now? No. The preview is a test environment. Existing access and permit arrangements still apply.
When does it become operational? Queensland plans full low-loader implementation in November 2026.
What changes then? NAAS becomes the default access pathway for eligible low loaders outside specified national notices, with permits remaining available where suitable access cannot be obtained through the automated system.
What should operators do now? TMR is encouraging operators to build their vehicle libraries and familiarise themselves with the system during the preview.
