Proposed Mass, Dimension Limit Increases Spark Debate

The Heavy Vehicle National Law Consultation Regulatory Impact Statement has generated lively discussion amongst HVIA members at recent State Committee Meetings

At last week’s State Committee Meetings, the presentation by Aaron de Rozario from the NTC on the Consultation Regulatory Impact Statement (C-RIS) for updates and changes to the Heavy Vehicle National Law (HVNL) review generated lively discussion amongst HVIA members.

The points of greatest interest and discussion included the proposed changes to mass and dimension limits.

Those changes included an increase to the current GML to account for Euro VI emissions and safety equipment, increasing GML to the current CML (and removing CML entirely), and increasing the general access length and height limits to 20 metres and 4.6 metres respectively.

The C-RIS is available here: Reforms to Heavy Vehicle National Law Consultation Regulation Impact Statement ( and Aaron de Rozario’s presentation is available here.

HVIA staff have prepared a draft response to the C-RIS incorporating member’s comments. Members interested in reviewing the draft response and providing further comment can contact Adam Ritzinger at or Greg Forbes at

Alternatively, members can provide a direct submission to the NTC at

HVIA will take all additional comments from members until November 17 and will then finalise its response and submit it to the NTC by the November 24 deadline.
