Van Modifications & VASS Certification in Victoria
Request a van modification quote | Book an inspection
Commercial Vehicle Compliance (CVC) provides engineering assessment and VASS certification for van modifications in Victoria. We work with commercial vans, light buses and specialist conversions involving seating changes, wheelchair access, body alterations, tailgate loaders, equipment installations and related compliance work. The applicable approval pathway depends on the vehicle category, GVM, modification and whether the vehicle is already in service.
Seating changes can affect a van’s vehicle category, tare mass, payload, occupant-protection requirements and registration description. Under current Victorian guidance, the applicable requirements depend on the seat category, vehicle category and whether the seating change alters the vehicle’s ADR classification. CVC can assess the proposed seating layout and advise whether VASS certification, updated mass information or additional evidence is required.
For more information about additional seating requirements please see the Seating page on this website. Click here.
Where a van conversion changes the vehicle into a light bus or another passenger-transport configuration, additional vehicle-category, seating, access and operating requirements can apply. These requirements should be identified before the conversion is completed.

Vans are commonly used for wheelchair-accessible vehicle conversions, but the floor layout, access system, seating, wheelchair positions, restraint anchorages and structural changes must be assessed for the particular vehicle. Victorian WAV projects can require VASS certification and must also satisfy the applicable Safe Transport Victoria requirements where the vehicle will operate as a commercial passenger WAV.

Tailgate loaders can be fitted to vans for loading and unloading heavy or bulky equipment. The installation needs to consider structure, mounting loads, rear overhang, axle loading, clearances and any effect on the vehicle’s compliance systems.
Vans can be modified for specialist applications including ambulances, campervans, wheelchair-accessible vehicles, mobile workstations, service bodies and other commercial uses. Each project should be assessed against the requirements that apply to the actual vehicle and intended use.
If you are planning a van modification, contact CVC before fabrication is complete so the likely engineering, inspection and certification requirements can be identified early.
