  • Registering a new trailer or caravan in Queensland.
  • Renewing the registration of an existing trailer or caravan over seven years old.
  • Transferring ownership of a trailer or caravan.
  • Taking a trailer or caravan interstate (some exceptions may apply).

Please note: This information page is intended as a general guide and may not cover all specific requirements. We recommend referring to the TMR website for the latest regulations regarding trailer and caravan RWCs.

Furthermore :

The document linked is a Vehicle Standards Bulletin (VSB 1 Revision 5) published by the Department of Infrastructure, Transport, Regional Development, Communications and the Arts (DITRDCA) in Australia. It outlines the design and construction standards for trailers with an Aggregate Trailer Mass (ATM) of 4.5 tonnes or less. These standards serve as an alternative to the stricter Australian Design Rules (ADRs) for low-speed trailers.

Here's a summary of the key points in VSB 1 Revision 5:


  • This bulletin establishes a simplified set of design and construction standards for trailers with an ATM of 4.5 tonnes or less.
  • These standards aim to be more practical and cost-effective compared to the ADRs, eliminating the need for some expensive testing procedures.
  • The standards reflect the common requirements of various Australian states and territories for trailer registration.


  • This VSB applies to both new and used imported trailers with an ATM of 4.5 tonnes or less.
  • Trailers seeking registration for the first time in Australia or intending to be used on public roads must comply with these standards.


Key Considerations:

  • Brakes: The trailer braking system must be sufficient to bring the trailer to a safe stop under various operating conditions.
  • Wheels and Tyres: Wheels and tyres must be appropriate for the trailer's weight capacity and intended use.
  • Coupling: The coupling mechanism must ensure a secure connection between the towing vehicle and the trailer.
  • Chassis and Suspension: The trailer chassis and suspension system must be robust enough to handle the expected load and ensure stable handling.
  • Lighting and Reflectors: The trailer must be equipped with functional lighting and reflectors for improved visibility on the road.
  • Labelling: The trailer must have a permanent label with essential information such as ATM, manufacturer details, and compliance statement.

Benefits of VSB 1 Compliance:

  • Provides a cost-effective alternative to ADR compliance for low-speed trailers.
  • Streamlines the registration process for trailers within the specified ATM limit.
  • Ensures trailers meet basic safety standards for operation on public roads.

Important Note:

While VSB 1 offers a simpler approach, it's crucial to remember that these standards apply only to trailers with an ATM of 4.5 tonnes or less. Trailers exceeding this weight limit must comply with the full ADR requirements.

I hope this summary is helpful! Remember, this information is for general understanding, and it's always recommended to refer to the official VSB document for the most accurate and detailed regulations.
