Pre COI Inspections

Pre-COI Diesel Truck & Trailer Inspections in South East Queensland

Ensure Your Heavy Vehicle is COI-Ready with Expert Pre-Inspection Services​

Operating a diesel truck or trailer in Queensland mandates adherence to stringent safety standards. Before undergoing the official Certificate of Inspection (COI), it’s crucial to ensure your vehicle meets all requirements to avoid costly re-inspections and downtime. Our pre-COI inspection service is designed to identify and rectify potential issues, ensuring a smooth and successful COI process.

What is a Pre-COI Inspection?​

A pre-COI inspection is a comprehensive assessment conducted prior to the official COI. It focuses on critical components such as brakes, steering, suspension, lighting, and overall structural integrity. By identifying and addressing defects beforehand, we help you avoid re-inspection fees and ensure compliance with Queensland’s safety standards.

Understanding Queensland's COI Requirements

In Queensland, certain vehicles, including heavy trucks and trailers, are required to undergo periodic inspections to ensure they meet minimum safety standards. A COI is issued when a vehicle passes this inspection. Vehicles must have a current COI at all times unless exempt. Failing to maintain a valid COI can result in penalties and the inability to renew vehicle registration. It’s advisable to have your vehicle checked for defects and book the inspection before the expiry date to avoid any disruptions.
