Notice development
Issues paper
The NHVR conducted an analysis and comparison of the existing national and transitional notices to produce a project scope statement and a comparative analysis. These documents provided the basis for identifying key issues to be addressed in developing a nationally harmonised B-double notice. The following paper addressed these key issues by proposing solutions to eliminate access inconsistencies experienced by operators.

- Jurisdictions to enforce the XY rule (balanced clear space rule) only on tri-tri B-doubles with a total gross combination mass exceeding 52.5 tonnes.
- Qld, NSW and SA to reassess their existing 23 metre B-double network to be consolidated into their 25/26 metre B-double network.
- SA to consider incorporating their nine commodity routes into a single 25/26 metre B-double network.
