COI PRE-INSPECTION

Understanding the Difference: Certificate of Inspection vs. Pre-Purchase Inspection

A Certificate of Inspection is a basic safety check conducted according to Queensland Transport’s Code of Practice. It ensures that the vehicle meets minimum safety standards but does not assess mechanical reliability or overall condition.

A Pre-Purchase Inspection, on the other hand, is a thorough condition report of the vehicle, providing potential buyers with detailed information about what they are purchasing. This inspection is highly recommended for any second-hand vehicle purchase as it can save money and provide peace of mind.

Note: A Safety Inspection is not a comprehensive mechanical inspection. Please inform us if you require a full mechanical inspection as well.

COI for Trucks and Trailers

Vehicles that are COI registered, such as trucks and trailers, must always have a current Certificate of Inspection due to the high risk of non-compliance from long-distance travel. When re-registering these vehicles, inspections and COI issuance must be performed by an Authorised Inspection Station (AIS).

Rapid Diesel Services is approved by the Department of Transport and Main Roads to conduct these inspections and issue Certificates of Inspection. Please contact us to schedule your vehicle for inspection.
