Which crashes are the most common among the elderly?

Various crash studies and surveys have shown that the elderly particularly have problems with turning left at intersections. In general, intersections are complicated traffic situations which involve time pressure and the necessity of dividing attention between various subtasks. These are task demands that the elderly relatively often experience as being difficult. Various sensory, perceptual, cognitive, and motor functional limitations which are part of the normal aging process and age related disorders could lie at the root of this.
