Future directions for older driver research.

The Western world is facing a growing proportion of older drivers on our roads as the population ages and, with, it a likely increase in crashes involving seniors. This paper sets out to review what we know about older drivers and what is still unclear and in need of future knowledge and intervention. Issues related to crash epidemiology, licensing, medical fitness-to-drive, the role of new safety technology, and life after the car are briefly reviewed with the aim of identifying key areas for future research and action. A list of priority topics is included to help address this burgeoning safety area.
