This report describes the results of a research project undertaken to investigate older driver risks and countermeasures. The literature on crash involvement of older drivers has been reviewed, crash statistics from the Federal Office of Road Safety database and elsewhere have been analysed, and qualitative research has been carried out with older drivers themselves as well as other relevant stakeholders. The report discusses the physical changes relating to aging and how this affects driving skills, including the type of crashes that old people are involved in. A number of countermeasures that may help reduce older driver crashes are canvassed, as well as communication strategies appropriate to this group.
