This study uses Kentucky crash data and linked hospital and emergency department records to evaluate whether the propensity for elderly drivers to be at fault in injury crashes can be more accurately estimated. Factors such as age, gender, and crash location are explored to assess their influence on the risk of a driver being at fault in an injury crash.

The overall findings are consistent with previous research: Elderly drivers are more likely than younger drivers to be at fault in a crash. Linking crash with hospital and emergency department records could also establish a clearer understanding of the injury crash propensity of all age groups and help transportation practitioners to design more targeted and effective countermeasures and safety programs.
