Certificate of inspection vehicle types and requirements

If the vehicle is unregistered or registered in another state or territory the first inspection must be obtained at an approved inspection station.

After the vehicle is registered, some high-risk vehicle categories must obtain their future COIs at a Department of Transport and Main Roads inspection site only. Other vehicle categories must obtain their COI from an approved inspection station only. Many vehicle categories have a choice of inspection provider.

The following is a list of Certificate of Inspection (COI) vehicle types and their inspection provider. You may need to know the purpose of use and the Gross Vehicle Mass (GVM) or Aggregate Trailer Mass (ATM) to work out the COI requirements for your vehicle. For buses, you may also need to know the registered seating capacity. You can check the purpose of use for the vehicle on the check registration status page.

All COIs are valid for 12 months, unless cancelled by the Department of Transport and Main Roads or by the registered operator.

A COI issued for a Heavy Primary Production Vehicle that has a registration concession is valid for 2 years after the registration concession is applied. The first COI issued before the registration concession is applied remains valid for 12 months only.

Vehicle categories that need a Certificate of Inspection (COI) are:

Note: A 2 axle mobile home or motorhome (single steer axle and single rear axle) cannot legally exceed 15,000kg when used on the road. However, the manufacturers rated GVM may be higher than 15,000kg. In this case, the manufacturer's GVM is not used for assessing inspection categories for motorhomes and campervans. A 2 axle mobile home or motorhome is considered to be under 16,000kg for determining the inspection provider, and is to be inspected at an approved inspection station.
