Heavy Vehicle Accreditation

In WA, operators of certain types of heavy vehicles must become accredited to gain a permit or order from Main Roads.
Western Australian Heavy Vehicle Accreditation is mandatory for individuals and organisations that require a permit or order to perform any transport task as part of a commercial business or for profit within Western Australia, including interstate operators.

Accreditation involves two modules - Fatigue and Vehicle Maintenance, which operators are required to incorporate into their daily work practices. With recent changes to legislation, there have been enhancements made to the WAHVA scheme which include the introduction of a Mass Management Module Standard, a Dimension and Loading Management Module Standard and changes to the WAHVA Business Rules. These additional modules are planned for inclusion in audit cycles from January 2016.

Accreditation does not exempt operators from complying with other requirements of the Road Traffic (Vehicles) Act 2012.

How to become accredited

If you have management systems in place for fatigue and maintenance and can provide sufficient operating records, you can have an Entry Audit conducted by an Exemplar Global auditor. Once you have a compliant Entry Audit you can submit it to Main Roads with the required payment and become accredited. This option will suit those who are already operating in some manner i.e. Interstate operators.

For those who are new to the industry or for those who do not have sufficient operating records, you may have a Systems Audit conducted by an Exemplar Global auditor. Prior to the audit you must establish your management systems for maintenance and fatigue. Once you have a compliant Systems Audit you can submit it to Main Roads with the required payment.  At this point you will receive provisional membership of the WAHVA Scheme for three months and have access to all RAV permit and order products required to operate a Class 1, Class 2 or Class 3 vehicle in Western Australia.  Prior to the end of the three month period, your Exemplar Global auditor must return and carry out a follow up audit which must be submitted to Main Roads.

Failure to submit a compliant follow up audit will result in revocation of your WAHVA membership.

An Operator guide on how to become and stay accredited and samples forms is available for your information.

The Accreditation guidelines and forms page provides further information on joining the WAHVA Scheme.

Please note: HVO Update 4-2013 outlines the WAHVA requirements applicable from 4 March 2013.
