(COI) Certificate Of Inspection
Vehicles over 4.5 tonne up to and including 16 tonne (RGVM)
Unregisterd Heavy Vehicles (including buses) over 16 Tonne
A Certificate of Inspection (COI) covers the basics that could affect the safe operation of the vehicle.
If the truck/unregistered 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 and 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 certificates 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.
