Most modern societies have been facing with a variety of social
problems owing to aging population. One of the problems would be
to grow the number of older drivers and to increase the number of
automobile accidents that the older drivers have involved. Thus, it
was discussed whether it would be appropriate to limit the validity
of older driver’s license, especially for commercial use, as a
preventive measure of the accidents in this paper. At the last part
of the paper, the authors maintain that a better driving aptitude
test to assess comprehensive abilities related to safe and quality
driving should be developed.
