(1) A person who drives, or permits another person to drive, a heavy vehicle on a road must ensure the vehicle, and the vehicle's components and load, comply with the dimension requirements applying to the vehicle, unless the person has a reasonable excuse.
Maximum penalty—
(a) if the heavy vehicle does not have goods or passengers in it—$3000; or

(iii) for a severe risk breach—$10000.
(4) If a PBS vehicle is authorised by its PBS vehicle approval to have a dimension that exceeds a dimension limit that would otherwise apply to the vehicle under a prescribed dimension requirement, the authorised dimension is taken to be the applicable dimension, and the vehicle is regarded for the purposes of this Law as complying with the prescribed dimension requirement.
(5) However, if a PBS vehicle is driven on a road other than in accordance with a class 2 heavy vehicle authorisation—
