Excess mass and dimension operations

Excess mass movements

The Guideline for Operation of Excess Mass (Form 11) is an alternate means of legally complying when the mass of a vehicle exceeds the mass requirements of the Heavy Vehicle (Mass, Dimension and Loading) National Regulation 2013.

The guideline establishes the vehicle and mass limits and conditions of operation of excess mass Special Purpose Vehicles (SPVs) to 40t and vehicles carrying an indivisible item to 59.5t.

The guideline conditions include route restrictions on the state-controlled road network. Approval for travel on local government roads must be obtained through the National Heavy Vehicle Regulator (NHVR).

The guideline also forms the foundation for the issue of excess mass permits, ensuring consistent and uniform excess mass permit management throughout Queensland.

The Guideline for Operation of Excess Mass (Form 11) is available from the NHVR Transitional Notices page.

Approved Heavy Haulage Operator (AHHO)

To operate an excess mass vehicle in Queensland an operator is required to register as an AHHO. Applicants must provide information such as company details and a list of persons authorised to sign on behalf of the company for permits. The AHHO application form (F4041) must be completed and faxed to (07) 3306 5502.

Authority to Operate (ATO)

Each SPV or prime mover operating in the excess mass scheme is required to obtain an ATO. The ATO will identify the vehicle as being eligible to participate in the scheme and will provide compliance personnel with data on the permitted operating mass of the vehicle. An ATO Form (F4042) must be completed with the following information and faxed to (07) 3306 5502.

The information required includes:

  • vehicle description and approved operating masses
  • supervised weighing of the vehicle
  • for a prime mover, proof of manufacturer's maximum load rating for axle groups, gross vehicle mass and maximum gross combination mass.

Excess mass permit operations

Excess mass permits will be required for the movement of vehicle above guideline limits. The guideline forms the basis for excess mass permits. Permits will exempt vehicles from a limit in the guideline and impose additional conditions necessary for the safe movement of the vehicle.

From 1 June 2017, Intelligent Access Program (IAP) monitoring is mandatory for some specified classes of heavy mobile cranes and special purpose vehicles that are eligible for excess mass permits of extended duration and radius. Conditions of operation for heavy mobile cranes and special purpose vehicles are located on the Excess mass and dimension conditions page.

Excess dimension movements

Excess dimension travel is based on the requirements of the Guideline for Excess Dimension in Queensland (Form 4), available from the NHVR Transitional Notices page. An excess dimension permit is required for travel over 4.5m wide and/or 5.0m high in critical areas or on critical roads as identified in the Critical areas and roads in Queensland map.
