National Heavy Vehicle Accreditation Scheme

The National Heavy Vehicle Accreditation Scheme (NHVAS) is a voluntary alternative to conventional heavy vehicle compliance. Accredited operators must demonstrate that their vehicles and drivers comply with standards set by NHVAS through regular audits of their transport management systems and vehicle or driver assessments.

The NHVAS is intended to increase transport efficiency by reducing the costs of compliance by allowing members greater flexibility in the management of their transport business.

The National Heavy Vehicle Regulator (NHVR) has been responsible for the management of the NHVAS since 21 January 2013.  For more information about NHVAS, please visit the NHVR website.


Under the national agreed NHVAS business rules all audits are to be conducted by an approved independent auditor. For more information about audits and auditors, visit the Audit framework and requirements page on the NHVR website.

Spot Checks

Transport and Main Roads' officers randomly conduct spot checks on scheme members’ accreditation management systems.

The objective of conducting Spot Checks is to indicate to the department that the accredited operators are complying with the conditions of approval and the NHVAS Accreditation Standards.
