This study focuses on the changes in driving characteristics of older drivers. A statewide survey of older drivers combined with focus group meetings was conducted. A total of 664 older drivers responded to a mail survey. Data were analyzed at three levels. First, the responses of all drivers to a certain question were investigated. Next, the data were divided into four age groups: 66 to 68, 69 to 72, 73 to 76, and 77 and more years of age. Finally, the differences in gender were examined. The survey results indicated that 70 percent of older drivers used their cars at least 5 days a week, and a higher proportion of male drivers than female drivers drove 7 days a week. The majority of older drivers did most of their driving in a town or a city, and as age increased, urban road use increased and highway use decreased. Nearly half of older drivers drove less than they did 10 years ago, and they drove fewer miles as their age increased. The majority drove frequently in off-peak hours, and age is a factor in deciding when to drive during a day. The older drivers recognized significant changes in their driving capabilities.
