You must ensure that a heavy vehicle that operates under this permit operates on an authorised route. Authorised higher mass limit routes are outlined by state and territory road transport authorities. This permit allows vehicles to travel only in stated areas or on authorised routes.
Information on the general mass limits and the higher mass limits can be obtained from the Regulator.
