Concessional Permits

Accredited Mass Management Scheme (AMMS)

This scheme was developed in conjunction with the Ministerial Heavy Vehicle Advisory Panel with the purpose of providing the WA transport industry:

  • an efficient concessional loading scheme;
  • a network approach;
  • road infrastructure protection and sustainability; and
  • greater flexibility in the type of loading controls used.

For more information on the scheme, please visit the AMMS page
