Heavy Trailers over 3.5 tonne to 10.0 tonne (ATM)

Unregistered Trailers over 10 Tonne


  • 5th Wheelers
  • Transporters
  • Pig Trailers
  • Dog Trailers


A  Certificate of  Inspection covers the basics that could affect the safe operation of the vehicle.


  • Identification
  • Modifications
  • Lights & Electrical Components
  • Body & Chassis
  • Suspension
  • Wheels & Tyres
  • Brakes
  • Tow Couplings


If the trailer complies in all of these areas in accordance to the Code of Practice then the Certificate of Inspection is issued on the spot.


What happens if I have a defect and it doesn’t pass on the first inspection?


Queensland Transport allows you 14 days from the first inspection date to have the defects repaired.

Once the repairs are completed, call us and we will come and complete the second inspection.

If the repairs are completed to the Code of Practice then the Certificate of Inspection will be issued.


If the heavy trailer is unregistered or is a new registration to Queensland you will require a HVRAS. This is a measure up of the trailer to ensure that it meets the standards set by Queensland Transport and Main Roads. You can have the HVRAS completed at Queensland Department of Transport and Main Roads. We also offer this service as a mobile service and can be completed at the same time as the Certificate of Inspection.


In some circumstances the trailer will need to go over a weighbridge. To confirm the exact paperwork/inspections required for your trailer contact Queensland Transport and Main Roads on 13 23 80.
