Main Roads Heavy Vehicle Services (HVS) is responsible for administering road access for Restricted Access Vehicles (RAVs).
RAVs are vehicles that exceed any of the following:
- a width of 2.5 metres;
- a height of 4.3 metres;
- a length of 19 metres for a vehicle combination;
- a length of 12.5 metres for a rigid vehicle;
- a gross mass of 42.5 tonnes;
- any other mass or dimension limit prescribed in the Road Traffic (Vehicles) Regulations 2014.
RAVs must only operate on roads approved by Main Roads, under either an order (notice) or a permit.
There are many types of RAVs and each of them has different performance characteristics, require a different amount of road space when operating and have a different impact on the road infrastructure. For this reason, it is necessary to assess the roads these RAVs operate on to ensure the road is suitable for the particular type of vehicle and the safety of other road users is not compromised.
Main Roads Heavy Vehicle Services (HVS) works collaboratively with the relevant road asset owner to ensure roads are suitable for RAV access. RAV Networks are maintained for the various types of RAVs and are published in the form of Road Tables and a RAV Mapping Tool.
Road Tables can be found on the following links:
Main Roads, in consultation with Department of Transport and the WA Local Government Association, developed the RAV Network Access Strategy. This Strategy is aimed at establishing and maintaining a Strategic Road Freight Network that will carry the bulk of heavy vehicle movements and ensure the roads receive adequate funding to sustain the volume of heavy vehicles.
Route Assessment Guidelines have been developed based on research conducted by Austroads, ARRB Group and the NTC. The Route Assessment Guidelines take into consideration the different performance characteristics of various RAV types and the impact they have on the road infrastructure and other traffic.
Route assessments must be conducted in accordance with the following Route Assessment Guidelines:
When conducting a route assessment, Assessors must use the following form:
The following Frameworks have been developed to further explain the processes and requirements related to added or removing roads from the RAV Networks:
All applications to have a road added or amended on a RAV Network must be submitted to HVS, using the following form:
Once the form is submitted, HVS will liaise directly with the relevant road asset owner to arrange a preliminary assessment of the road and seek their support. HVS will then coordinate the formal route assessment and approval process, and then inform the applicant and road asset owner of the outcome.
The following document has been developed to provide guidance to Main Roads staff responsible for making decisions related to RAV access and to provide an understanding to stakeholders on the decision making process:
