What is a Certificate of Inspection (COI)?

A Certificate of Inspection (COI) is a thorough safety check of a vehicle to ensure it meets the minimum requirements set out in the Queensland Light Vehicle Inspection Manual. This inspection is vital for vehicles intended to carry paying passengers, whether it’s a taxi, limousine, or rideshare vehicle (Uber, DiDi, GoCatch, etc.).

Why Do You Need a COI?

A yearly COI is mandatory when a vehicle is being used to carry paying passengers, such as for taxis, limousines, or ridesharing platforms like Uber, DiDi, Shebah, and GoCatch. Without a COI, your vehicle cannot legally be used to transport paying passengers.

The Queensland Light Vehicle Inspection Manual

The Queensland Light Vehicle Inspection Manual is the foundation for COI inspections. All Approved Inspection Stations and Examiners in Queensland must adhere to the guidelines outlined in this manual when conducting a COI. This ensures a consistent and standardised approach to vehicle safety, providing peace of mind for both operators and passengers.

Pre-Inspection Checklist

Before booking your COI inspection, it’s helpful to check the following to avoid any surprises:

Lights

Ensure all lights are functioning correctly, including headlights, taillights, and indicators.

Horn

Test that the horn is functioning properly.

Tyres

Verify that your tyres have at least 1.5mm of tread in the grooves in the middle of the tyre.

Oil Leaks

Make sure there are no oil leaks dripping onto the ground.

Windscreen

Check for cracks or star fractures that could obstruct the driver’s view or damage the wiper blades.

Brake Lights

Pay attention to brake lights, which can be harder to check without assistance.

Common Issues That May Cause a COI Failure

Some of the most common issues that may cause a COI inspection to fail include:
  • Non-functioning lights, such as headlights, brake lights, and indicators.
  • Worn-out tyres with tread depth under the required 1.5mm.
  • Oil leaks.
  • Cracks or chips in the windscreen.
  • Faulty horn.
These requirements help ensure that all vehicles on Queensland roads meet essential safety standards.
