Abstract
Intending to review the results of a previous investigation the driving behaviour of 182 drivers was registered by 40 rating scales. The values obtained were studied in a factor analysis. Seven driving behaviour factories were obtained which were compared with the factors obtained in the first analysis by means of an additional evaluation process. Moreover the 182 drivers took a test including a total of 60 variables were validated with regard. A- to the seven driving behaviour factors; B- to the criterion of the general impression of the driving manner; C- to the criterion of the explored number of accidents; D- to the criterion of the road test score.
