Heavy Vehicle (Mass, Dimension and Loading) National Regulation (NSW)

The higher mass limits apply as an exception to the general mass limits as stated in subsections (2) to (5).

The mass on the single axle or axle group must not be more than the following (the mass exception amount)—

for a tandem axle group other than a 6-tyred tandem axle group—17t;

for a 6-tyred tandem axle group—14t;

for a tri-axle group—22.5t.

The mass of the vehicle must not be more than the mass determined by applying section 2 of Schedule 1 with the amount stated for the single axle or axle group in Table 1 of Part 2 of the Schedule changed to the mass exception amount.

Subsection (5) applies if, because of the application of subsection (1) to a single axle or axle group within a particular axle spacing, the mass permitted for the vehicle is increased under subsection (3) by an amount above the general mass limits for the vehicle.

The mass relating to the axle spacing must not be more than the general mass limits for the axle spacing increased by the amount.

This section has effect subject to section 3.
