Operating a heavy vehicle

Intelligent Access Program - heavy vehicles

The Intelligent Access Program Higher Mass Limit scheme has been discontinued in South Australia.

Operators are no longer required to comply with the conditions in the following notices that relate to operating under the IAP or the completion of Higher Mass Limit route compliance certificate:


The Intelligent Access Program (IAP) was introduced in South Australia in 2010, on a voluntary basis, as an alternative means for operators who were accredited in an interstate National Heavy Vehicle Accreditation (NHVAS) mass management schedule to comply with SA’s requirements for Higher Mass Limit (HML) operation.

The nationalisation of the NHVAS through the introduction of the Heavy Vehicle National Law has resulted in all operators (including those registered interstate) having equal access to the published HML networks in SA without the requirement to either complete a HML route compliance certificate or enrol in the IAP.

This combined with the request from the National Heavy Vehicle Regulator (NHVR), through the National Notice Harmonisation Project to remove the requirement for a HML route compliance certificate to be completed by operators renders IAP in SA, non-operational as there is no longer a valid IAP application.
