Vehicle Standards Bulletin 14 (VSB 14)

National Code of Practice for Light Vehicle Construction and Modification (NCOP)

The National Code of Practice for Light Vehicle Construction and Modification (VSB 14) has been prepared by members of the Australian Motor Vehicle Certification Board Working Party in consultation with industry, user groups, government agencies and individuals with an interest in modifying light vehicles and/or building individually constructed light vehicles (ICVs).

VSB 14 is a ‘live’ document and will continue to be revised and updated as required.

The documents listed below form Version 2 of VSB 14 and are now available for free download in PDF format.

VSB 14 essentially provides the technical requirements that need to be met when modifying or constructing a vehicle. It does not cover the administrative requirements of each State and Territory.

Administrative requirements include, but are not limited to:

  • Registration processes;
  • Fees for processes such as registration, issue of temporary permits, vehicle inspections; applications for approval to modify, applications for exemptions etc.;
  • Determination of the date of manufacture for Individually Constructed Vehicles;
  • Processes for submitting applications; and
  • Administration and management of modification schemes including the administration of signatories.

The Preface and Introduction to VSB 14 provide the necessary background information to assist users in understanding how VSB 14 is administered by the Registration Authorities across Australia. Understanding and following these requirements reduces the likelihood of having a vehicle rejected by a Registration Authority.

Prospective constructors or modifiers should contact the Registration Authority in the jurisdiction in which a vehicle is to be registered or modified, to determine the most up to date information about the administrative arrangements that may be in force.

Where a jurisdiction is unable to nationally recognise an element of VSB 14, the individual difference/s are highlighted within VSB 14. In these instances, users should contact the responsible Registration Authority for further advice.
