Abstract

This study was designed to carry out an in-depth exploration of an extended version of the Theory of Planned Behaviour. Fifty licensed drivers took part in the study and each one was given three different driving scenarios; speeding in an urban area, dangerous overtaking and speeding on a major road. The results indicated that drivers usually find speeding acceptable although this was also related to a context, since speeding on a major road was more acceptable than on a minor one. The immediate response to the question about consequences of the act varied and depended on the perception of the situation. In a serious situation the response was purely affective and immediate whereas in a low risk situation it was more considered. The response to the question about subjective norm was sometimes difficult to answer or misunderstood which throws some light on its weak association with intention. Driving skills were explored in some detail together with its possible link to perceived behavioural control. In general those participants who believed themselves to be superior to others, expressed high degrees of control. The study also found that a low degree of perceived behavioural control (external or internal) could be used as a form of justification for carrying out an act although this only applied to a situation which they perceived as low risk. In a high-risk situation they always tried to maintain their own control. Habit, or rather past behaviour, influenced future behaviour when the experience had been positive. The police, or feelings of regret, could break this pattern. The implications of these findings in relation to theoretical and practical issues are discussed.
