“Vehicle compliance” can describe several different jobs. A manufacturer preparing a new model for the Australian market, a body builder modifying an existing truck, and an operator arranging an in-service inspection may all need different evidence and approvals. The first question is what is happening to the vehicle, and when?

1. A vehicle being supplied to the Australian market for the first time

Under the Road Vehicle Standards (RVS) framework, a road vehicle generally needs an applicable pathway for entry on the Register of Approved Vehicles (RAV) before it is first provided for road use in Australia. Vehicle type approval is one pathway for supplying a type of vehicle; concessional RAV entry may apply to eligible individual vehicles or small numbers. The applicable Australian Design Rules (ADRs), vehicle category, evidence and approval holder responsibilities need to be established early.

CVC helps manufacturers, importers and second-stage manufacturers plan the evidence and application pathway. See our ROVER and type approval support, vehicle import guide, and comparison of second-stage manufacture and modification approval. The Australian Government explains RVS legislation and vehicle type approvals.

2. An existing vehicle being modified

Once a vehicle is in service, the question is whether the proposed change needs engineering assessment and approval under the relevant state or territory scheme. In Victoria, the Vehicle Assessment Signatory Scheme (VASS) covers modified, individually constructed and certain imported vehicles. The signatory’s authorisation and the vehicle category determine the work they can certify.

For heavy vehicles, the NHVR classifies modifications by approval pathway. VSB6 provides technical requirements for many common heavy vehicle modifications; some changes need an Approved Vehicle Examiner (AVE), while others require NHVR approval. Confirm the pathway before fabrication, particularly for chassis, wheelbase, body, seating, brakes, mass ratings or lifting equipment. A VASS signatory in Victoria can act as an AVE for work within their authorisation. Read our Victorian VASS guide, heavy vehicle modifications service and interstate approval planning guide.

3. An in-service inspection

A roadworthiness or in-service inspection checks the vehicle against applicable inspection criteria. It does not, by itself, approve a modification that needs an engineering certificate or modification label. This distinction matters when a customer asks for a “compliance inspection” without specifying whether a vehicle was changed. Our heavy vehicle inspection guide explains the difference.

What to send before an engineering assessment

• Vehicle identification, category, current registration jurisdiction and manufacturer ratings.
• A complete list of proposed or completed changes, including changes that may need separate labels.
• Drawings, component specifications, installation instructions, calculations and relevant test evidence.
• Clear photos of the vehicle, identification plates, affected structures and completed work.
• The intended operating state or territory and whether the vehicle has already entered the RAV.

CVC can review the project and identify the likely approval and evidence path before an inspection. Send us the vehicle and modification details; the final requirements depend on the vehicle and the signatory’s assessment.
