View the PBS 1 Network Map

This Class 2 network shows roads mapped in three categories: Approved (green), Conditionally Approved (orange) and Restricted (red). Click on a route or bridge to show any conditions that apply.

The network shows roads which can be accessed by PBS Level 1 compliant heavy vehicles operating under the National Class 2 PBS Level 1 & 2A Truck and Dog Trailer Authorisation Notice 2021, or the National Class 2 Performance Based Standards (Tier 1) Authorisation Notice 2021, and all other PBS Level 1 compliant combinations operating under a permit.

Restricted structures (red dots) must not be crossed.

Roads not shown as approved (green) or conditionally approved (orange) require road manager approval for access by permit.  Application for access by permit is to be made through the NHVR.  It is permitted to travel off route if the road is marked with detour signage.

Operators must check for road closures and road conditions prior to travel to ensure clear passage.  For roads managed by Department of State Growth this information is available on the Department of State Growth website, or on this map by selecting “Road Works - State Roads" via the "Layer List"  icon.

Higher Mass Limits (HML) Roads

Roads which are part of the Tasmanian Declared HML Route Network can be superimposed on the map by selecting “HML Advisory layer” via the “Layer List” icon.

Unless otherwise stated in a permit:

  • An approved PBS 1 combination cannot operate over the HML network unless the road also appears on the PBS 1 network map.
  • The applicable HML gross combination mass and individual HML axle group masses are those which pass using Tier 1 Bridge assessment methodology, as stated in the vehicles’ PBS Design Approval document.
