Approved Inspection Station Scheme overview

Before a registered vehicle can be offered for sale, or when an unregistered vehicle is being re-registered, the vehicle must be inspected to ensure it meets minimum safety standards. An Approved Inspection Station can inspect certain types of vehicles. If the vehicle is free from defects and safe to use on a road, they may issue one of the following inspection certificates:

  • safety certificate, previously called a roadworthy certificate
  • certificate of inspection.

What is an Approved Inspection Station?

An Approved Inspection Station (AIS) is either a:

  • premises used as a fixed AIS, such as a mechanical workshop
  • premises used as a fixed AIS and a vehicle used as a mobile AIS.

The AIS approval holder is responsible for:

  • making sure the premises meet local, State and Australian government requirements
  • ensuring the AIS has the necessary approval to do vehicle inspections at the premises, for example, local government approval to carry out vehicle inspections at the premises.

The premises must have a dedicated and suitably sized inspection area and the necessary equipment to inspect all types of vehicles listed on the AIS approval. Learn more about requirements for inspection areas and equipment.

Type of vehicles inspected at an AIS

We may approve an AIS to inspect light and/or heavy vehicle types depending on:

  • the size of the premises and inspection area
  • equipment kept and maintained at the premises.

The following tables describes the vehicle types that an approved-AIS may inspect.

Vehicle inspections

An AIS must have an approved examiner who is approved to inspect the types of vehicles listed on the AIS approval. Approved examiners are responsible for:

  • identifying the vehicle
  • inspecting the vehicle
  • ensuring the vehicle is not defective and is safe to use on a road before approving an inspection certificate.


Find out how to apply to be an approved examiner, and what qualifications and experience you need.

If an approved examiner considers that a vehicle is not defective and is safe to use on a road, they may approve an inspection certificate. The approved examiner then gives it to the AIS approval holder (or their nominee) to issue the inspection certificate to the driver or the vehicle owner.

Find out how to apply to have a nominee and more about when an AIS is required to have one.

Inspection certificates

When an approved examiner inspects a vehicle, they must record the vehicle identity and inspection results. This is done electronically using Inspection Certificates Online or handwritten on an inspection certificate from an inspection certificate book.

Inspection Certificates Online (ICO)

ICO is a web portal and mobile application that allows an AIS to electronically complete and submit inspection certificates direct to the Department of Transport and Main Roads.

Using ICO is free and may save the cost and time taken to purchase inspection certificate books. However, all AISs must have at least 1 inspection certificate book for each vehicle type they are approved to inspect. This also applies to AISs using ICO, as you may need handwritten inspection certificates when ICO is unavailable, for example, when there are internet or power outages.

Read more about Inspection Certificates Online (ICO).

Inspection certificates books

You may purchase inspection certificate books from your nearest transport and motoring service centre.

Inspection certificate books are not available for CL and CM vehicle type inspections. An AIS and approved examiner must use ICO to issue COIs for CL and CM vehicle type inspections.
