The objective of this study is to understand the driver needs from a preventive and protective perspective focusing on cognitive pre-crash factors influencing the older driver in intersection collisions. The study combines information from a statistical dataset and 33 in-depth cases. The statistical data confirms results from prior studies indicating that the 55+ drivers are relatively more involved in collisions occurring in intersections having an overall higher injury risk compared to the comparative group of drivers aged 25-35. The in-depth data indicates that missed observations were one major cause in the development of the collision scenarios studied. The major possible causes together with the contributing causes are analyzed and discussed
