Summary

This 1993 report, prepared by the National Highway Traffic Safety Administration (NHTSA) in response to a request from the U.S. Senate Committee on Appropriations, outlines the agency’s research agenda for addressing safety issues among younger drivers (ages 15–24) and older drivers (ages 65+). The document distinguishes between these two high-risk groups by analyzing crash statistics, driver characteristics, and underlying risk factors to inform future behavioral and engineering interventions. The analysis reveals that while both age groups exhibit higher crash rates per mile traveled than intermediate-aged drivers, the magnitude and nature of their risks differ significantly. Younger drivers are involved in four times as many reported crashes and three times as many fatal crashes as older drivers. Their crashes are primarily driven by behavioral factors, including inexperience, poor judgment, risk-taking, and alcohol involvement, with excessive speed cited as the primary error in 15% of their crashes. Conversely, older drivers have lower overall crash frequencies but higher fatality rates due to increased physical fragility. Their crashes are more frequently associated with declining cognitive and perceptual capabilities, such as difficulties with right-of-way violations and left turns, rather than risky behaviors. Older drivers also drive fewer miles, particularly at night, and are less likely to be involved in alcohol-related incidents. NHTSA’s proposed research agenda addresses these distinct profiles through separate strategies. For younger drivers, the focus is on understanding risk-taking behaviors, peer influences, and youth culture. Planned efforts include developing targeted educational materials, improving enforcement and adjudication procedures (such as provisional licensing and lower blood alcohol concentration limits), and utilizing advanced technologies like driving simulators and warning systems. For older drivers, the agenda prioritizes linking declining physical and mental capabilities to driving safety. This involves developing guidelines for medical practitioners and licensing agencies to identify at-risk drivers, creating retraining programs to improve performance at intersections, and assessing vehicle crashworthiness and restraint systems to mitigate injury severity. The report also emphasizes evaluating whether Intelligent Vehicle & Highway Systems technologies might overload the decision-making capacities of older drivers. The significance of this report lies in its structured approach to tailoring safety interventions to the specific etiologies of crash risk for each demographic. By separating behavioral interventions for young drivers from capability-based assessments and vehicle design improvements for older drivers, NHTSA aims to balance public safety with the mobility needs of aging populations. The report underscores that while the older driver problem is smaller in scale, it requires precise, medically informed solutions, whereas the younger driver problem demands broad, multifaceted behavioral changes.

Key finding

Younger drivers have vastly higher crash and fatality rates than older drivers, but older drivers have a greater fatality rate per mile driven and are more than three times as likely to die in a crash once involved.
