Higher Mass Limits (HML) is a nationally agreed scheme that permits approved heavy vehicles to operate with additional mass on certain types of axle groups, on a restricted road network and subject to specified conditions.

(For more information on Higher Mass Limits please go to: http://www.ntc.gov.au)

Participation in the HML scheme requires registration in each applicable state and territory. Further information, including application procedures, operating conditions and applicable route maps, is available from road agency websites:
