Poor hazard perception (HP) abilities correlate with young-inexperienced driversÆ over-representation in traffic crashes. HP ability can be examined by the degree of perceived hazard associated with a situation (i.e., howdrivers rateclassify hazardousness). However, this form of evaluation wasneglected in favor of measurement of perception-reaction time to perceived hazards. We argue that classification should be re-considered. In two similar studies, drivers with different driving experience completed two consecutive tasks: (1) observation of traffic-scene movies while pressing a response button each time they detected a hazard; and (2) observation of the same movies again and classifying them according to similarities in their hazardous situations. In both studies young-inexperienced drivers tendedto classify the movies according to similarity in their actual hazards whereas experienced drivers relied more on traffic-environment characteristics in their classification. With experience, drivers perceive more potential hazards and relate to traffic-environment characteristics. HP training programs should emphasize the tight link between traffic environment and specific hazards by including these factors when constructing the hazard perception movies database.
