Certificate of inspection vehicle types and requirements

The following is a list of Certificate of Inspection (COI) vehicle types and who inspects vehicles for COI renewals. You will 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 will 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.
