Approved inspection station code of practice

An image of a car on a hoistThe Code of Practice – Vehicle Inspection Guidelines is for approved inspection stations to use when inspecting motor vehicles for the purposes of issuing an inspection certificate. This document replaces the Approved Inspection Station Proprietor's Guide, commonly known as the 'causes for rejection'.

The code of practice is divided into three sections. An overview of each section is provided below.

Heavy vehicles

Complex modifications to heavy vehicles and trailers over 4.5 tonne GVM/ATM (gross vehicle mass/aggregate trailer mass) can be certified by approved persons, providing the modifications have been performed in accordance with the National Code of Practice for Heavy Vehicle Modifications – Vehicle Standards Bulletin 6*. This national standard is available for free from the federal Department of Infrastructure and Transport website*.

Light vehicles

Complex modifications to light vehicles such as engine, gearbox, axle, steering and brake replacements can be certified by an approved person, providing the modifications have been performed in accordance with the Department of Transport and Main Roads (formerly Queensland Transport) Code of Practice – Light Vehicle Modifications.

All approved persons have the code of practice. Copies of the code of practice are available for sale through the Queensland Government Bookshop.

Approved persons

Driving a vehicle with modifications that have not been approved is illegal. A modified vehicle that has not been approved can be put off the road immediately by police or Department of Transport and Main Roads inspectors. Drivers of vehicles that have not been approved may also find that they are not covered by insurance.

The Approved Person Scheme provides a quick and easy way to have most modifications approved and reduces the chance of a costly traffic fine or having your vehicle ordered off the road.

Approved persons inspect modified vehicles to ensure they comply with the code of practice. The approved person will give you a Certificate of Modification and fit a modification plate to the vehicle if the changes meet the required standards.

A fee will normally be charged for any vehicle inspection and approval. This fee is not set by this department. Approved persons set their own fees which may vary depending on the modifications and the time involved in the inspection.

Approved persons either independent businesses or are employed by private industry and are authorised by this department to approve vehicle modifications. Approved persons are located across Queensland and the names and addresses of approved persons are available at Department of Transport and Main Roads customer service centre.

Approved persons don't have to modify the vehicle. You can still do the modifications yourself or have them done for you. However, it is strongly suggested that an approved person is consulted before commencing any modification to find out the relevant standards for approval. There are some modifications which still require approval from the Department of Transport and Main Roads.

The scheme allows approved persons to approve modifications done by others provided the modifications meet the standards set by the code of practice.
