Abstract
Previous research has suggested that drivers may react to other drivers on the bases of logically insuppurtable inferences. In the present study drivers were asked, in a paper-and-pencil test, to make judgements about the causes of one or two violations of the highway code committed, ostensibly, either by themselves or by 'someone of your age and sex'. There was a marked tendency for these subjects to attribute their 'own' behaviour to primarily situational factors whilst attributing that of the 'others' to primarily dispositional factors. Implications for road safety propaganda are considered.
