the extent to which a person is influenced by information, instructions or attitudes provided by other people, whether directly (e.g. direct instructions or warnings) or indirectly (e.g. observing other people’s behaviour or reporting in the media). From a psychological point of view, suggestibility is due to many factors:
1) Personal qualities – for example, trust in others, inclination to obedience and the degree of independence of opinion.
2) Environment – social situation, stress level, boredom or tension while driving.
3) Indicative signals – the way information is presented, the power of authority and the clarity of the message.
