Transport and Main Roads (TMR), Queensland, will commence a transition period from 1 December 2022 until 31 May 2024, such that:

  • From 1 December 2022, any new enrolments of eligible HML vehicles must be in the scheme of the TMA application only. From this date, eligible HML vehicles must not enrol in the related IAP scheme.
  • If an eligible HML vehicle was enrolled in the related IAP scheme before 1 December 2022, it may continue its enrolment until 31 May 2024. Enrolment may be cancelled in the IAP scheme and commenced in the scheme of the TMA application if eligibility criteria are met.

For the TMA HML scheme, mass and vehicle configuration must be declared through a user interface provided by the ASP. However, if an enrolled vehicle has a TCA-approved Smart OBM system installed, mass and vehicle configuration data is required from this device rather than via self-declaration.
