Accredited Mass Management Scheme

Accredited Mass Management Scheme...

  • allows for three (3) concessional mass levels; and
  • doesn't prescribe specific loading methods nor restrict commodity types

Instead, AMMS allows for any product and any proven loading control method to be used.

To be eligible for AMMS, operators must be accredited under the WA Heavy Vehicle Accreditation (WAHVA) Mass Management Module.

AMMS Application Process

  • 6 or 12 month duration available
  • Cost - $4 per tonne, per month over the Road Traffic (Vehicles) Regulations 2014 limit
  • AMMS Permit Application form

AMMS Approved Weighbridge list

An approved weighbridge can be used by transport operators as their sole loading control method when addressing the criteria for the relevant standard in the Mass Management Module.

For a weighbridge to be included on the AMMS Approved Weighbridge List it must be able to determine and record both:

  • the gross mass of the vehicle; and
  • individual axle group weights.

The weighbridge operator must also provide us with current certification or calibration documentation with their AMMS Weighbridge application form (PDF)

Concessional Road Networks



Approved roads (network tables), restricted structures and agricultural pilot zones are provided in one easy-to-use map.
