Summary
This 1982 report by the National Public Services Research Institute, commissioned by the National Highway Traffic Safety Administration (NHTSA), addresses the traffic safety challenges associated with elderly drivers, defined as those aged 55 and older. The study was motivated by the increasing proportion of senior drivers and the specific physiological and cognitive declines—such as reduced visual acuity, hearing loss, and slower reaction times—that affect driving performance. While elderly drivers have fewer total accidents than younger counterparts due to lower mileage, they exhibit higher accident rates per mile, are more frequently at fault, and suffer more severe injuries. The primary objective was to determine optimal design guidelines for retraining programs that help older drivers maintain safe performance despite age-related deficiencies. The research involved five major activities: a literature review of aging-related driving problems, a review of 20 existing driver education courses for the elderly, a controlled evaluation of the "55-Alive" program developed by the National Retired Teachers Association/American Association of Retired Persons (NRTA/AARP), the development of a new instructional manual, and the formulation of recommendations for future programs. The core evaluation focused on the eight-hour "55-Alive" curriculum, which was introduced in California, Florida, Illinois, and Virginia. The study design compared participants who completed the course against a control group of older drivers whose enrollment was delayed. Data collection instruments included driver experience questionnaires and knowledge tests administered before and after the training, alongside analysis of official accident and violation records. Findings from the evaluation indicated that the "55-Alive" program was effective in increasing participants' knowledge of safe driving principles. However, no significant effect on accident rates was detected. The authors noted that the sample size was too small to rule out a modest but significant reduction in crashes. Analysis of the broader data set revealed that crash experience among older drivers was primarily a function of driving exposure and medical problems rather than training status. The literature review identified common performance errors among older drivers, including failure to yield, improper turns, and careless backing, often linked to cognitive limitations and hesitation. Based on these findings, the report concludes that while age does not diminish the ability to learn, specific retraining is necessary to address the unique needs of older drivers. The authors developed an "Older Driver Manual" suitable for wide distribution and provided detailed recommendations for future programs. These recommendations emphasize content that addresses physiological changes, environmental hazards, and specific behavioral adjustments, rather than generic driver improvement material. The study underscores the need for targeted educational interventions to mitigate the higher per-mile risk and injury severity associated with elderly drivers.
Key finding
The 55-Alive program significantly increased knowledge among elderly drivers but showed no statistically significant effect on accident rates due to sample size limitations.
