Lessons learned through the development and implementation of an evaluation for medically at-risk drivers

The aging of the population is transforming the demographics of the driving population in most industrialized countries of the world. In North America, one in every four drivers will be over the age of 65 within two decades. Not only are there more seniors driving than ever before, but they also are driving more and longer into old age (Stutts et al., 1989; Eno Transportation Foundation, 2000) where crash-risk is highest.
