An analysis of reports of 660 two-car collisions from the records of an insurance company showed that car drivers of 60 years old and older are more apt to be considered liable in an accident than younger drivers. A comparison of accidents for which older drivers (60 yrs. and over) are responsible with accidents for which younger drivers (30–39 yrs.) are responsible showed that the former have problems of perception and decision making and that the latter have problems with speed.
