What is a Certificate of Inspection (COI)?
A COI is a mandatory inspection in Queensland that confirms a heavy vehicle like a truck or trailer meets safety and roadworthiness standards. It is required periodically to keep your vehicle legally registered and on the road.
How often do I need a COI for my diesel truck or trailer?
Most heavy vehicles in Queensland require a COI annually, but the frequency can vary depending on the vehicle type and use. Always check with the Queensland Department of Transport or your mechanic for specifics.
Why should I get a pre-COI inspection?
A pre-COI inspection helps you identify and fix potential issues before your official COI. This reduces the risk of failing the inspection, avoids rebooking fees, and ensures your vehicle remains compliant.
What does your pre-COI inspection include?
We inspect key components such as:
- Brakes and suspension
- Steering and tyres
- Lights and electrical systems
- Fluid leaks
- Structural condition
- Safety equipment
Do you offer repairs if my truck or trailer fails the pre-COI?
Yes. If any issues are found during the pre-COI inspection, we can provide the necessary repairs or maintenance to bring your vehicle up to compliance standards.
How long does the pre-COI inspection take?
Most inspections are completed within a few hours, depending on the vehicle’s condition. We aim to minimise your downtime while providing a thorough assessment.
Where do you provide services?
We service diesel trucks and trailers throughout South East Queensland—including the Gold Coast, Brisbane, and Sunshine Coast.
