A driver's decision governs his behaviour. these decisions in turn depend on attitudes and values of the driver. An important part in increasing traffic safety is to change the attitudes. However, the occurence of these changes is difficult to measure. How is it for example, that campaigns directed towards drunken driving have effect, while campaigns concerning speeding do not ? Actually, we do not know if or why propaganda works. The purpose of this presentation is to discuss possible conditions that could be used in order to modify attitudes. A model is presented in which a person's expectations and values, together with social criteria impact his or her attitudes and intentions. The aim is to point out alternative methods for defining the causes of driver behaviour.
