Class 1 Oversize Overmass Permits

Transport for NSW (TfNSW) has introduced a new option for vehicles performing Oversize Overmass (OSOM) movements in NSW.  

Under the new arrangements, transport operators can benefit from extended duration permits by enrolling in the Road Infrastructure Management (RIM) application.   


  • Laden permits, a 12-month permit can be obtained (instead of 3 months) 
  • Unladen permits, a 3-year permit can be obtained (instead of 12 months). 

From 1 June 2020, transport operators are required to submit their applications for access to both state and local council roads via the National Heavy Vehicle Regulator (NHVR) Portal.

Participation in the RIM application, which is administered through TCA as part of the National Telematics Framework, is one of these requirements.

Alternatively, transport operators can enrol in the Telematics Monitoring Application (TMA) or Intelligent Access Program (IAP) applications.
