Excess mass and dimension operations
Although it is necessary to minimise damage to structures and pavements by fixing regulation mass and dimension limits, it is also recognised that some concessions must be given to the transport industry to allow the movement by road of heavy and large vehicles and loads.
Regulation mass and dimension limits are detailed in the Transport Operations (Road Use Management – Mass, Dimensions and Loading) Regulation 2005.
Main Roads has responsibility for the management of the operation of excess mass vehicles and loads.
Queensland Transport has responsibility for the management of the operation of excess dimension vehicles and loads.
This management seeks to minimise impacts on the safety of road users and the impact on traffic and road assets on Queensland's road network.
Excess mass movements
Management of excess mass is either by the Excess mass guidelines (PDF, 229 KB) or an excess mass permit issued through one of our permit management offices.
More information can be found on the Excess mass operations page.
Excess dimension movements
Excess dimension travel is based on the requirements of Performance guidelines: form numbers 4, 6, 7 and 14. Travel in excess of 4.6 m width requires a Letter of No Objection issued by a Main Roads permit management office.
An excess dimension permit is required for travel over 5.5 m wide and/or 4.8 m high. These permits are issued by the Queensland Police Service.
More information can be found on the Excess dimension operations.
