Trucks (Heavy Vehicle Inspection) 

Certificate Of Inspection

  • Vehicles over 4.5 Tonne up to and including 16 Tonne (RGVM)
  • Unregisterd Heavy Vehicles (including Buses) over 16 Tonne
  • Defect notice clearance


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


  • Identification
  • Modifications
  • Seats & Restraints
  • Lights & Electrical Components
  • Windscreen & Windows
  • Body & Chassis
  • Steering & Suspension
  • Wheels & Tyres
  • Brake Components
  • Engines & Drivelines
  • Exhaust Emissions
  • Road Test
  • Service Brake Test
  • Hand Brake Test

If the truck/unregisterd Bus 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.

(Re-Inspection charges apply to mobile services)

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


What do I need to do if my truck is unregistered?


  • You need at least Compulsory Third Party Insurance on the vehicle
  • A copy of the Department of Transport’s New Registration Application Form signed by the owner

How often do I need to have a Certificate of Inspection?


Heavy vehicles are required to have a valid Certificate of Inspection every 12 months. Queensland Transport and Main Roads will send a reminder notice approx. 12 weeks prior.


The Certificates of Inspections are a time sensitive Certificate. Please see the guidelines below.


  • If the heavy vehicle is inspected up to 1 month before the current Certificate Expires, the new Certificate will not be allocated to the vehicle until the previous Certificate of Inspection expires.
  • If the heavy vehicle is inspected more than a month before the current Certificate of Inspection expires then the new Certificatees Inspection date will become the valid certificate date.

If you are unable to complete the inspection in the time required and it expires, you will need to contact the Department of Transport and Main Roads to apply for an extension of time.

"Thank you very much for the report. The mechanic was very generous with his time (30 minutes or so) in providing a verbal feedback to me. As I live in Canberra, getting the report done was the best value for money I have achieved. It saved me un necessary expense in getting to Queensland and pursuing a car that ultimately had far more issues than I had expected. In addition, I consider myself somewhat 'car savvy' but your inspector definitely picked up stuff that I would never have identified. There is no doubt in my mind the inspection was highly detailed and the money well earnt. Thank you again for your support, and should I look at purchasing any more cars in Queensland, I will definitely be seeking an M1 report before I seriously consider a purchase. cheers and thanks a million.
