The National Heavy Vehicle Regulator (NHVR) has issued five new notices in partnership with the South Australian Department for Infrastructure and Transport (SA DIT), aimed at improving freight efficiency and delivering more productive networks across the state.
Heavy vehicles that may benefit from the new notices include livestock vehicles, high productivity combinations, and tri drive prime mover and rigid truck combinations.
The new notices include:
National Class 2 B-double Authorisation Notice 2026 (No.1) – amended to include prime movers with tri-axle groups.
National Class 2 Road Train Authorisation Notice 2026 (No.1) – amended to include prime movers with tri-axle groups.
National Class 2 Performance Based Standards (High Productivity) Authorisation Notice 2026 (No.1) – amended to include a South Australian schedule and the incorporation of Euro VI mass provisions.
South Australia Class 3 Road Friendly Suspension Mass Exemption Notice 2026 (No.1) – amended to include rigid trucks and prime movers with tri-axle groups.
South Australia Class 3 Livestock Transportation Mass and Dimension Exemption Notice 2026 (No.1) – amended to include road train combinations.
Commenting on the new notices, NHVR Chief Operations Officer Paul Salvati said, “This is a strong example of the NHVR working closely with government and industry to deliver practical, on-the-ground improvements.
“These changes demonstrate our commitment to supporting industry and improving productivity – particularly at a time when we know industry are facing increased cost pressures.”
The NHVR says the increased capacity will mean more goods can be moved in a single trip, while reducing administrative burden by removing the need for some permits, cutting road manager consent requests, and providing greater certainty of access for operators.
These changes formed part of a significant body of work undertaken by the NHVR under the South Australia Minister Commitment program, which aimed to reduce permits by transitioning access to notice.
The publication of these notices was fast-tracked at the request of the South Australian Government, to help ease fuel and cost pressure.
Salvati said the changes would deliver real benefits for operators and road managers alike. “By expanding access through notices, we are reducing red tape, improving certainty, and helping operators get on with the job,” he said.
