This Technical Summary announces the completion of an FHWA study that is fully documented in a separate report (FHWA-RD-95-194) of the same title. 

Limited-access highways and the Interstate highway system have been largely responsible for greatly increasing the mobility and safety enjoyed by the American driving population. However, as the driving population ages, it is not known if the requirements for a driver using the freeway system are compatible with the capabilities of older drivers. The purpose of this study was to identify the problems experienced by older drivers on freeways and to recommend further research to make freeway driving more compatible with the needs and capabilities of older drivers.
