National Class 2 Road Train Authorisation Notice – Network and Mapping Update
Isaac Regional Council is advising heavy vehicle operators of upcoming changes to the National Class 2 Road Train Authorisation Notice network, as communicated by the National Heavy Vehicle Regulator (NHVR).
What is changing
The NHVR has introduced a new network mapping capability for Road Train access. As part of this update:
- The current shaded access areas for Type 1 and Type 2 Road Trains will be phased out.
- These shaded regions will be replaced with individual road‑by‑road access approvals and restrictions.
- This change affects operators using Isaac Regional Council roads under the National Class 2 Road Train Authorisation Notice.
Why the change is occurring
The new mapping system is intended to provide clearer, more accurate, and more responsive information regarding approved Road Train routes across Australia. Operators will now be able to see specific road segments rather than broad shaded areas, improving network reliability and safety.
When will the changes take effect
Under the Heavy Vehicle National Law (HVNL):
- Amendments and/or cancellations take effect 28 days after the NHVR publishes a Network Suspension and Amendment Notice.
- The NHVR published the March Network Update on Thursday, 5 March 2026, meaning the changes will take effect from Thursday, 2 April 2026.
Right to make representations
Any person affected by these amendments may make written representation to the NHVR (rm.enquiries@nhvr.gov.au) within 14 days of the publication, outlining why the amendment(s) should not be made.

Isaac Regional Council is providing this information as a secondary communication to support industry awareness. All formal notifications are issued by the NHVR.
