In Western Australia, WAHVA is mandatory for individuals and organisations which 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.
WAHVA involves three mandatory modules Fatigue, Maintenance and Dimension and Loading, which transport operators are required to incorporate into their daily work practices. There is one optional module -The Mass Management Module - which is only required to be undertaken if an operator wishes to operate within the Accredited Mass Management Scheme (AMMS).
