In Victoria a Certificate of Roadworthiness is generally required when a vehicle is sold or if a used vehicle is to be re-registered. This helps minimise the number of poorly maintained vehicles on the road.
In some cases a Certificate of Roadworthiness is also required to clear a Vehicle Defect Notice or a Notice of Unroadworthiness.
Who issues certificates?

A Certificate of Roadworthiness can only be issued by a licensed vehicle tester, operating from a nominated garage or service station. All Car Service Centre is licensed vehicle testers.
When can a certificate be issued?

The vehicle must pass a roadworthy inspection, then a certificate is issued.
What is inspected?

The inspection is a check of the vehicle to ensure that key components have not worn or deteriorated and that the vehicle is safe for normal road use.
A roadworthy inspection mainly covers the major safety related items, including:

wheels and tyres
steering, suspension and braking systems
seats and seat belts
lamps and reflectors
windscreen, and windows including front windscreen wipers and washers
the structure of the vehicle itself
other safety related items on the body, chassis or engine.
The roadworthiness test is not a check of the mechanical reliability or general condition of the vehicle. If you require a comprehensive check on the overall condition and reliability of the vehicle then you should arrange for a separate report offered by All Car Service Centre.
The certificate does not mean:

that the vehicle is in top condition without any wear or deterioration
non-safety related accessories such as the air conditioner, rear window demister, electric windows and rear-window wipers are working
that the items checked during the roadworthy inspection will continue to function after the inspection eg. a brake light can stop functioning at any time after the inspection.
What if the vehicle fails the test?

If an item fails to meet the standard, We will issue a rejection report. You will be given seven days to repair the item/s rejected and return the vehicle to us for a second inspection of the failed items. If more than seven days elapse a complete inspection must again be carried out on the vehicle.
How much does the test cost?

The cost of obtaining a Certificate of Roadworthiness is not fixed. It may depend on the age, type and condition of the vehicle being examined. You can ask for a quote from us.
How long does a certificate last?

A Certificate of Roadworthiness is current, for the purposes of a transaction, for 30 days from the date of issue.
What about the Australian Design Rules?

The roadworthiness test is not a complete assessment of a vehicle’s compliance with the Standards for Registration, which, in most cases, are the Australian Design Rules (ADRs). The ADRs are a set of minimum standards for the construction of motor vehicles and trailers. In most cases compliance with these standards cannot be assessed by inspection alone.
