292ARestricting movement of load

292A Restricting movement of load (1) A driver must not drive or tow a vehicle carrying a load unless the load is restrained by a load restraint system that: (a) prevents the load from moving in relation to the vehicle (other than movement allowed under subrule (2)) in the circumstances mentioned in subrule (3); and (b) at a minimum, is capable of withstanding the forces that would result in the circumstances mentioned in subrule (3).

Traffic Regulations – Australian Road Rules 291 (2) A load may move in relation to the vehicle if: (a) the vehicle's stability and weight distribution are not adversely affected by the movement; and (b) the load does not become dislodged from the vehicle. Examples of load movement that may be permitted under subrule (2) 1 A load contained within the sides or enclosure of the vehicle that is restrained from moving horizontally may be able to move vertically. 2 A load of very light objects, or a loose bulk load, that is contained within the sides or enclosure of the vehicle may be able to move horizontally and vertically. 3 A bulk liquid load contained within the sides or enclosure of the vehicle. (3) For subrule (1)(b), the circumstances are that the vehicle is subject to: (a) any of the following, separately: (i) 0.8g deceleration in a forwards direction; (ii) 0.5g deceleration in a rearwards direction; (iii) 0.5g acceleration in a lateral direction; and (b) 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. g means gravitational acceleration or 9.81 m/s2.
