This study describes the fatal crash experiences of older drivers. Data from two U.S. databases (NASS-CDS and PARS) were used. Several crash, vehicle, and occupant characteristics were compared across age groups, including vehicle type, crash direction (PDOF), severity ( Delta V), and injured body region. A sub-set of 97 fatally injured drivers was chosen for a detailed case study. The mean travel speed, Delta V, and airbag deployment rate decreased significantly with age (p<0.001 unless noted). Mortality rate increased significantly with age. Older drivers killed were significantly more likely to die of a chest injury (47.3 % vs. 24.0 % in youngest group) and less likely to die of a head injury (22.0% vs. 47.1% in youngest group). Older drivers were more likely to die at a date after the crash date ('delayed death'), as were males (p=0.003). A 16-year-old driver had a 10.8 %-12.0 % probability of delayed death, while a 75-year-old had a 20.7 %-22.7 % probability. For those having a delayed death, the length of the delay increased significantly with age (2.9 days for age 16 vs. 7.9 for age 75). A subjective assessment of the case files indicated that frailty or a pre-existing health condition played a role in 4.3 % of the younger drivers' deaths, but 50.0 % of the older group.
