What is a Trailer Roadworthy or Safety Certificate?

A Trailer or caravan roadworthy inspection or Safety Certificate inspection is the process of getting your trailer or caravan inspected by an Approved Examiner so it can be registered and used on public roads.

All trailers and caravans with an Aggregate Trailer Mass (ATM) of more than 750kg must be issued a roadworthy before being registered for use on Queensland roads.

Without a roadworthy, your trailer or caravan cannot be registered or the registration transferred legally in Queensland. 

Your trailer should have a Vehicle Identification plate, normally on the draw bar, which will have a stated Aggregate Trailer Mass or ATM.

Light trailers with an Aggregate Trailer Mass (ATM) up to and including 750kg may be registered in Queensland by the owner completing a vehicle details form – contact your nearest Transport and Main Roads Customer Service Centre for more information.

Light trailers and caravans with an ATM of  751kg to 4500kg require a Safety Certificate inspection to be registered, or in order for the registration to be transferred from a seller to a buyer.

If the trailer is unregistered or is registered in another state in Australia, it will also require a HVRAS inspection or ‘measure up’ in addition to a Safety Certificate inspection.

Why Do You Need A Trailer Safety Certificate?

In Queensland, it’s a legal requirement for every trailer between 750kg ATM and 4500kg ATM to be issued a Safety Certificate before it can be registered and used on public roads.

You will need a trailer Safety certificate in situations such as:

  • First-time Registration: Brand-new or previously unregistered trailer.

  • Transferring Ownership: When buying or selling a trailer.

  • Registering an Interstate Trailer: Transferring registration from another state into Queensland.

Without a Safety Certificate inspection, trailers cannot be legally used, sold, or transferred. It’s an essential step to ensure your trailer is safe, compliant, and road-ready.
