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

A load on a heavy vehicle must be restrained by a load restraint system that—

prevents the load from moving in relation to the heavy vehicle (other than movement allowed under subsection (2)) in the circumstances mentioned in subsection (3); and

at a minimum, is capable of withstanding the forces that would result in the circumstances mentioned in subsection (3).

A load may move in relation to the heavy vehicle if—

the vehicle’s stability and weight distribution are not adversely affected by the movement; and

the load does not become dislodged from the vehicle.

Examples of load movement that may be permitted under subsection (2)—

• a load contained within the sides or enclosure of the heavy vehicle that is restrained from moving horizontally may be able to move vertically

• a load of very light objects, or a loose bulk load, that is contained within the sides or enclosure of the heavy vehicle may be able to move horizontally and vertically

• a bulk liquid load contained within the sides or enclosure of the heavy vehicle

For subsection (1), the circumstances are that the loaded vehicle is subjected to—

any of the following, separately—

0.8g deceleration in a forward direction;

0.5g deceleration in a rearward direction;

0.5g acceleration in a lateral direction; and

if friction or limited vertical displacement is relied on to comply with paragraph (a)—0.2g acceleration in a vertical direction relative to the load.

However, the heavy vehicle’s load restraint system is taken to comply with subsection (1) for a journey if—

a mass or dimension exemption is in force for the vehicle for the journey; and

the vehicle complies with the mass or dimension exemption; and

an engineer has given a certificate—

describing the load restraint system; and

certifying that the load restraint system is suitable to safely restrain the load, taking into consideration the nature of the load and the conditions reasonably expected to be experienced during the journey; and

the driver of the vehicle keeps a copy of the engineer’s certificate in the driver’s possession during the journey.

Note.

Mass or dimension exemptions are dealt with in Division 2 and Division 3 of Part 4.5 of the Law.
