Older drivers are primarily overinvolved in crashes at intersections, and failure to attend to regions that contain relevant information about potential hazards is a major contributor to this problem. Corroborating this, we have found that older drivers in both controlled scenarios on a driving simulator and somewhat less controlled situations on the road attend to (i.e., fixate) target regions in intersections significantly less frequently than do younger experienced drivers. Moreover, we have developed a training program that substantially improves older drivers' attention to these regions. Together, these findings indicate that older drivers' less frequent scanning of regions at intersections from which hazards may emerge may be due to their developing something like an unsafe habit rather than to deteriorating physical or mental capabilities and thus that training may be effective in reducing crashes.
