About Certificates of Inspection
Certificate of Inspection (COI) vehicles (such as heavy vehicles, licensed tow trucks, buses, taxis, limousines and booked hire vehicles) registered in Queensland may need to have a periodic or programmed inspection to check minimum vehicle safety standards. A COI is issued when the vehicle passes the inspection.
Owners of registered COI vehicles must have a current COI at all times, unless exempt.
The vehicle must be presented in a clean condition and free of excessive grease to ensure the components can be inspected.
The vehicle should be checked for defects and have any necessary repairs completed before presentation for a COI to prevent the need for a re-inspection.
Depending on your vehicle type, a COI can be obtained from City Fleet Transport Maintenance (an approved inspection station accredited by Transport and Main Roads).
Find out about the different COI vehicle types and requirements.
Unregistered vehicles can also get an inspection certificate from City Fleet Transport Maintenance.
Generally, you will receive a reminder notice around 10 weeks before your COI expires—but it’s your responsibility to ensure your COI vehicle has a current COI.
You can check registration status online or using the QLD Rego Check app to see when your COI expires.
If a COI vehicle is inspected:
- up to 2 month before the current certificate expires, the new certificate will not begin until the current certificate expires
- more than 2 month before the current certificate expires, the new certificate will commence from the date the vehicle was inspected
- after its previous certificate expires, the expiry date of the new certificate will be calculated from the expiry of the previous certificate (e.g. if your COI is normally due on 1 July but you have it inspected on 1 August, your new COI will commence on 1 July.
It is an offence to drive a vehicle with an expired COI unless you have a COI exemption or an extension of time to comply.
Generally, an extension of time is only available if the vehicle needs an inspection at a Department of Transport and Main Roads inspection centre and there are no available booking slots. Contact the Department of Transport and Main Roads to enquire about extensions of time.
