Class 1 Vehicles

View Victoria’s network maps if you’re driving Special Purpose Vehicle (SPV, including Mobile Crane, Concrete Pump Truck etc); an Oversize Overmass (OSOM) load carrying combination, (including Low Loader & Platform Trailer combinations); a Heavy Tow Truck (see OSOM map) or seeking Victoria’s preferred Over-Dimensional (OD) Routes.

All authorised heavy vehicle road network maps are now published by the National Heavy Vehicle Regulator, through the NHVR National Network Map.

To ease the industry’s transition to the National Maps, Victoria’s heavy vehicle network maps will continue to be updated on the VicRoads’ website in the short-term.

For all road closures, traffic alerts, roadworks and detours, or events causing road closures and/or detours, this Planned & Unplanned Disruptions map layer should be applied to the heavy vehicle network intended for use. NOTE: The route to be used must also be checked prior to travel. The Disruptions data will be viewable on the HV map network you are checking by toggling on once in the highlighted layers widget above the information panel.

The five pre-approved single trip permit networks for low loader combinations operating at up to 131.0 tonnes gross mass, 6.0 metres high, 6.0 metres wide, and 32 metres long, are:

  • Reference vehicle 17: Prime mover & 5x8 short low loader combination up to 100.0 tonnes with minimum GCW of 4.2m;
  • Reference vehicle 23: Prime mover & 5x8 long low loader combination up to 100.0 tonnes with minimum GCW of 4.2m;
  • Reference vehicle 22: Prime mover, 2x8 dolly & 5x8 low loader combination up to 113.5 tonnes with minimum GCW of 3.5m;

The three pre-approved networks for prime mover, dolly and platform trailer combinations, operating on a period permit at up to 193.0 tonnes gross mass, 6.0 metres high, 6.0 metres wide, and 44 metres long, are:

  • Reference vehicle 16: Prime mover, 2x8 dolly & 10x8 platform trailer combination up to 176.0 tonnes with minimum GCW of 4.2m;
  • Reference vehicle 15: Prime mover, 2x8 dolly & 11x8 platform trailer combination up to 188.0 tonnes with minimum GCW of 4.2m; and
  • Reference vehicle 14: Prime mover & 14x8 platform trailer combination up to 193.0 tonnes with minimum GCW of 4.3m.

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 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:

Platform Trailer Structures

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

View the Over Dimensional (OD) Route Network map

Victoria’s Over Dimensional (OD) Vehicles network map. This map shows the preferred network of arterial and municipal roads that cater for OD combinations that exceed 5.0 metres high or 5.0 metres wide or 30.0 metres long or 100.0 tonnes gross mass. These OD routes have been chosen because they have minimal height and width impediments or mass restrictions.

The routes are mapped in different colours for specific OD routes. The (broken lines) on certain routes in the regional network indicate proposed OD routes. Routes 5A and 5B (light blue) in the metropolitan network are alternate routes to be used only when authorised  by VicRoads Permits Section

  • OD Route 5A is an alternate route for OSOM combinations that are not permitted to travel via the West Gate bridge.
  • OD Route 5B is an alternate route for OSOM vehicles that are not permitted to travel via the Dandenong Bypass.

NOTE: This map is for information only and does not reflect temporary changes to the network such as road closures or detours. Operators of OD vehicles must check the VicTraffic map on the VicRoads website for road closures and road conditions prior to travel to ensure clear passage. Travelling off the preferred network requires written road manager approval or direction by an authorised officer.

Access for these OD vehicles is managed through conditions such as escorts and travel time restrictions stated in an OD Vehicle Permit. To obtain a permit to operate an OD vehicle, please submit your Class 1 permit application via the NHVR website (External link).
