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.
