Certificate of Inspection (COI) Mobile Truck, Bus & Heavy Trailer Inspections
In Queensland, heavy vehicles over 4.5t GVM, buses, taxis, limousines, and heavy trailers over 3.5t ATM require an annual Certificate of Inspection (COI). We provide mobile COI inspections directly at your depot, yard or job site.
What is a Certificate of Inspection (COI)?
A Certificate of Inspection (COI) is a compulsory annual safety check for heavy vehicles registered in Queensland. Unlike a standard light vehicle safety certificate (which is valid for 2 months), a COI is a recurring requirement that must be renewed every 12 months to maintain valid registration on Queensland roads.
Vehicles Requiring a COI in Queensland:
- Heavy trucks over 4.5t GVM (Prime movers, tippers, pantechs, fire trucks)
- Heavy trailers & horse floats over 3.5t ATM
- Large motorhomes & heavy caravans
- Public passenger vehicles, buses, taxis & limousines
Bundle COI + HVRAS Inspections Onsite
If you are registering an interstate truck or heavy trailer in Queensland for the first time, you may need both a COI and an HVRAS assessment. We can perform both checks simultaneously during a single mobile visit to save you downtime and money.
