2.1.7 Hand signals
• Signals given by an assistant operator if the driver cannot
see the travelling or working area or machine work devices.
• The following principles must be observed:
- only a limited number of signals must be used for com-
munication purposes,
- the signals must be easily distinguishable to prevent
confusion,
- hand signals can only be used in case the environmental
conditions support clear communication between per-
sons,
- hand signals must be as similar as possible to intuitive
movements,
- one-hand signals can be given by any hand.
EXAMPLES OF COMMUNICATION SIGNALS:
