It is applicable to the above trucks:
- with a seated operator;
- fitted with fork arms or attachments;
- with fixed or articulated chassis;
- which may have stabilizers, axle-locking or frame-levelling devices;
- with two- or four-wheel or articulated steering systems;

This International Standard is not applicable to trucks when handling suspended loads which may swing freely.
