Higher mass limits
Please note, from August 2010 changes to the higher mass limits policy now allows operators to apply for additional higher mass limits access on routes that are not already approved as a road train or B-double route as previously required.
When operating at higher mass limits, operators must ensure that the higher mass limit route is approved for their particular vehicle combination:
- Road trains operating at higher mass limit weights can only operate on approved road train routes (as per the multi-combination approved routes – any conditions applied to the route must be adhered to).
- B-doubles operating at higher mass limit weights can only operate on approved road train and B-double routes (as per the multi-combination approved routes – any conditions applied to the route must be adhered to).
- Single drive axle buses are permitted extra mass under the Transport Operations (Road Use Management – Mass, Dimensions and Loading) Regulation 2005. Therefore they are no longer eligible for extra mass under the higher mass limits policy.
Queensland has a policy that allows vehicles fitted with road-friendly suspension to carry more freight on routes that are capable of accepting higher masses.
Higher mass limits (HML) were first introduced to Queensland on 2 July 1999. Initially, the scheme was limited to the former national highway system and connecting 23m and 25m B-double routes within a radial distance of 500m.
In December 2002, the Queensland Government introduced a policy framework that allowed extensions based upon agreement from the road asset owner.
The Intelligent Access Program (IAP) is now available for vehicles operating at higher mass limits. This national program provides heavy vehicles with improved access to the Australian road network in return for monitoring compliance with specific access conditions. This is done by installing vehicle telematics in participating vehicles which includes a combination of global positioning systems, in-vehicle sensors, and additional communication technology. Enrolment in IAP is a mandatory requirement for HML.

Expansion of the higher mass limits network
The Queensland and Commonwealth Governments have entered into a Bilateral Infrastructure Agreement (BIFA) in accordance with the Auslink program. The agreement encourages a staged rollout of extensions to the existing higher-mass-limit network in conjunction with additional responsibilities for road transport operators.
On 1 October 2006, the Queensland Government expanded the number of higher-mass-limit approved routes to meet its obligations under the Australian Government's Auslink program.
Queensland's current policy for requesting extensions will still apply while Bilateral Infrastructure Agreement obligations for both the Queensland Government and road freight industry are met. Higher-mass-limit routes are approved only after an agreement to use the road has been obtained from the road owner, and the proposal has been endorsed by the Department of Transport and Main Roads.
A more detailed explanation of the policy is provided in the higher mass limits information bulletin (updated August 2010)
