Where the IAP is specified as a condition of access, transport operators enrol vehicles into the IAP, and engage an IAP Service Provider to monitor access and compliance against agreed conditions of access.  

The IAP operates through the legislated interaction of four different parties, each with defined roles and responsibilities:

  • Transport Operators – gain access entitlements to the road network through the IAP as a condition of that access
  • Road Agencies/Road Managers – specify access entitlements and conditions through the IAP
  • IAP Service Providers – provide IAP services to transport operators
  • TCA – ensures that IAP Service Providers are certified and audited, and administers the IAP on behalf of its Member organisations, including supporting the development and implementation of the IAP. (TCA is not involved in setting the policy and conditions of the IAP).

National Legislation

Chapter 7 of the Heavy Vehicle National Law Act 2012 (Qld) (Queensland Act) provides the legal and privacy framework for the IAP. To achieve nationally consistent legislation, the Queensland Act serves as the model Heavy Vehicle National Law (HVNL) which is then adopted by other jurisdictions enacting consistent legislation. The HVNL currently applies in Queensland, New South Wales, Victoria, Tasmania and South Australia.

For other jurisdictions, the IAP can be applied as a condition of access by road managers and regulators.
