Why do older drivers have more 'failed to look' crashes? A simulator based study

Older drivers seem to be over-represented in traffic accidents at intersections where the older driver is turning against oncoming traffic, when the right of way is on the major road. This study sought to determine if there is a correlation between "failed to look" driver errors and visual-cognitive deficits. Driving simulator and laboratory tests were utilized to determine cognitive and visual performance when driving, and in general. It was found that older drivers do have reduced visual abilities, and their driver experience often enables them to compensate for these deficits. Evidence from driver behavior also shows that older drivers are over-represented in "failed to look" traffic accidents. It is suggested that driver training programs and support technology could help.
