(a – f) Approved testing facilities in Western Australia are listed on ROVER, the Australian Government Department of Infrastructure, Transport, Regional Development, Communications and the Arts’ online applications and approvals portal. It is not compulsory for testing facilities to be listed on ROVER.
Dynamometer testing at an approved facility can be used to provide evidence as part of an application to adjust the approved Gross Combination Mass of a vehicle.
The Department of Transport’s engineers assess a range of evidence as part of an applicant’s submission to ensure the application meets the requirements of VTB-181A with sound evidence.
