This paper presents a study where measures of exposure - the time spent driving and distances driven - by drivers over 60 are related to their risk of accidents. The elderly drivers are compared with other adult drivers (aged 25 to 59). Their reports of problems experienced while driving are examined and compared by age group, sex and region. The result of the study was that the comparison between trip times and distances makes it clear that differences in exposure between age groups is not due to changes in trip length, but in numbers of trips taken. Comparison between men an women at the same ages suggests that differences in driving environment exist. Finally drivers over 80, both male and female, have a substantially greater risk of crash than any other group.
