Performance Based Standards (PBS) Level 2A Network

View the PBS 2A 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 2A compliant 3 or 4 axle rigid trucks towing a 3, 4 or 5 axle dog trailer operating under the National Class 2 PBS Level 1 & 2A Truck and Dog Trailer Authorisation Notice 2021 (No. 1), and all other PBS Level 2A 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 and by selecting the “show state growth road works” button on this map.

Higher Mass Limits (HML) Roads

Roads which are part of the Tasmanian Declared HML Route Network can be superimposed using the “Show HML Network” Button.

Unless otherwise stated in a permit:

  • An approved PBS 2A combination cannot operate over the HML network unless the road also appears on the PBS 2A 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.
