The Road Vehicle Standards Act 2018 (RVSA) has replaced the Motor Vehicle Standards Act 1989 (MVSA). The operational aspects of the RVSA are contained in the Road Vehicle Standards Rules 2019 (the Rules). The RVSA, the Rules and other related legislation are collectively referred to as the RVS legislation.

What is the Register of Approved Vehicles

The Register of Approved Vehicles (RAV) is a publicly searchable database of vehicles that have met the requirements of the RVS legislation and been approved to be provided to the Australian market. The RAV replaced the need for physical compliance (ID) plates to be fitted to vehicles.

All road vehicles—cars, trucks, trailers, caravans and so on—must be entered on the RAV before they can be provided to the market for the first time in Australia.

Entry on the RAV is almost always a prerequisite for being able to register a vehicle for road use.

The RAV has two approval pathways—vehicle type approval or concessional RAV entry approval. Manufacturers, suppliers and importers need to decide which pathway is appropriate for each vehicle type.

What is a vehicle type approval?

Vehicle type approval is the pathway to allowing an unlimited number of vehicles of a particular type to be imported and/or entered on the RAV. It identifies the applicable national road vehicle standards for a road vehicle type and specifies the documents required to confirm compliance with them. This option is generally used for commercial quantities of road vehicles.

What is a concessional RAV entry approval?

Concessional RAV entry approval is the pathway for importing and/or entering road vehicles on the RAV one-by-one on behalf of an approval holder. For example, specialist and enthusiast vehicles. A separate application is required for each road vehicle.

How do I apply for an approval?

All applications are submitted through ROVER, our online applications and approvals portal.

Where can I find more information?

Guidance materials providing further information on the RVS application processes and links to other useful resources can be accessed at Guides and resources, including ROVER how-to videos and videos on various RVS topics.

Changes to road vehicle standards the effect electrical wiring on trucks and trailers

There has been a change in the wiring of the electrical connector plug & socket of the truck/trailer connection.

This change has been made with the amendment from Australian Design Rules (ADR), ADR42/04 to ADR42/05.

Within ADR42/04 the wiring needed to comply with AS2513. With the amended ADR42/05 the electrical wiring of trailers above 3.5t ATM must comply with AS4735. The previous standard (AS2513) has been removed from the ADR.

The new trailer plug and wiring won’t fit most trucks in the field unless they are built after a certain date. An adapter will be needed. Customers may need to be made aware of this, especially if they intend to pick up the trailer with their own trucks.

This will have a major effect on most Australian vehicles as older vehicles have been wired to the AS2153 and when the plug is used with wiring in accordance with AS4735 the old plug will not fit the new socket and vice versa. In order to remedy this situation, it is recommended that an adaptor plug should be used. These adaptors can be purchased from Redmond Gary Australia.
