A key feature of these networks is that all structural conditions can be viewed on each individual map, removing the need for operators to seek a structural assessment.
Victoria’s Platform Trailer Network information sheet [PDF 387 Kb] has been developed to work alongside these maps and provide clarity around questions arising about unladen travel, pilot requirements, travel time restrictions and the general responsibilities that each operator must comply with. (Operators should read this information sheet before applying for a permit through the NHVR).
Roads NOT shown on these maps as approved (green) or approved with conditions (orange) have either been assessed and restricted (red) for reasons of mass, geometry or amenity, or have yet to be assessed. Access to restricted (red) roads will not be granted.
Uncoloured roads require additional road manager approval via a separate NHVR Access Permit, except for signed detours. These maps are deemed to include any detour around a road closure on a pre-approved road, provided it is marked with detour signage.
Operators must comply with structure mass, height clearance and rail crossing restrictions/instructions as indicated by the following symbols:

Operators must also plan their trips and review intended routes before travel.
