Frequently Asked Questions

What is a VASS Certificate?
A VASS Certificate is an engineering approval issued in Victoria for vehicles that have been imported, modified or do not meet standard compliance requirements.
The certificate confirms that a vehicle has been assessed and meets the applicable safety and design standards under the Vehicle Assessment Signatory Scheme (VASS). This certifications is required before certain modified or imported vehicles can be legally operated on public roads.
Why do I need a VASS Certificate?
A VASS Certificate is required when a vehicle has been imported into the country, or modified in a way that affects its safety, structure, performance or compliance with road regulations. This includes modifications such as engine swaps, suspension changes, body alterations, seating changes, wheelchair lift installations, or braking upgrades.
The certificate ensures that the vehicle meets all relevant engineering and safety standards before it can be registered or driven legally on public roads in Victoria.


What are the fees involved?
The cost of a VASS Certificate varies depending on the type of vehicle and the complexity of the modifications involved. At JEC, pricing is based on a structured fee schedule according to the scope of work required for each project.
To provide an accurate quotation, clients are required to submit a Build Plan form so the vehicle and modifications can be properly assessed prior to commencement of works.
What modifications require a VASS Certificate in Victoria?
VASS Certificates are required when vehicles are modified in a way that affect safety, structural integrity, performance, emissions or compliance with Victorian road regulations.
Common modifications include engine or drivetrain swaps, suspension changes, body or chassis alterations, seating configuration changes, roll cages, braking upgrades, and imported vehicles.
In general, any modification that changes the vehicle from its original manufacturer specifications may require assessment and approval under the VASS scheme.


What happens during a VASS inspection?
VASS inspections typically include reviewing the vehicle’s modification history, assessing the quality of workmanship, and checking the modified areas of the vehicle. Where required, engineering calculations, testing, and supporting documentation may also be reviewed.
Inspections are typically completed within approximately one hour, and can be carried out at our facility or at a suitable location anywhere across Victoria, as we provide a mobile inspection service statewide.
Once the inspection is completed, an engineering report is issued to the vehicle owner. This report outlines the findings of the assessment, including any areas that require rectification in order to meet compliance requirements.
Where can VASS inspections be completed?
VASS inspections can be completed either at our dedicated assessment facility or at a location that suits you. We operate from a fully equipped inspection site in Yarraville, Victoria, fitted with a hoist and all necessary tools to carry out detailed engineering assessments.
For clients who are unable to bring their vehicle to us, whether due to defect notices, unregistered status, or logistical constraints, we also offer mobile inspection services. Our equipment and processes are designed to allow assessments to be conducted at workshops, homes, or other suitable locations.
This flexibility ensures that inspections can be completed with minimal disruption while still meeting all engineering and compliance requirements.


What documents are required before an inspection?
Clients are primarily required to complete our Client Agreement Form, which captures key vehicle details and the scope of modifications. From there, we manage the assessment process, including identifying applicable standards and required checks.
Supporting documents may be requested depending on the nature of the modifications. These can include a weighbridge ticket, a dynamometer report, or any existing engineering reports or compliance documentation.
If you are unsure whether specific documents are needed, we will guide you prior to the inspection to ensure the process runs smoothly.
Can vehicle defects be cleared with a VASS Certificate?
A VASS certificate does not directly clear a defect notice, but it may form a critical part of the defect clearance process. In Victoria, defect notices are typically issued by Victoria Police when a vehicle is identified as non-compliant or unsafe. The notice will outline the requirements that must be met before the vehicle can be returned to the road.
In many cases, a Roadworthy Certificate (RWC) is required to clear the defect. However, if the defect relates to vehicle modifications, the vehicle may first require engineering approval through the VASS scheme.
The exact requirements depend on the details listed on the defect notice. If you have received a defect, we can review it and advise on the correct path forward
