This National Code of Practice applies to modifications to heavy vehicles both prior to their first sale in Australia (new vehicles) and after their first sale in Australia (vehicles in service).
For the purpose of this National Code of Practice, a heavy vehicle is defined as a motor vehicle with a Gross Vehicle Mass (GVM) greater than 4.5 tonnes or a trailer with an Aggregate Trailer Mass (ATM) greater than 4.5 tonnes.
This does not preclude the use of this code for other categories of vehicle, where appropriate.
The code provides detailed requirements and examples of acceptable practice for a range of common modifications. It supplements the recommendations of the original vehicle manufacturer in relation to vehicle modification techniques or standards and provides guidelines where manufacturers standards do not exist. It is not intended to cover every eventuality.
Please consult the Agency Contact Officer for more information and to ascertain the level of compliance (if any) that may be required.
