Two fully-instrumented intersection-type collision experiments are briefly described. Variations in the dependent variables are presented, as determined by the independent variable of car vintage. Modern domestic cars appear to be less likely to upset during intersection collisions, doors are more likely to remain closed, and collision forces tend to be slightly reduced, compared with cars manufactured some ten years ago. Special studies currently underway at U.C.L.A. are briefly described concerning the car door latch, its window glass, headlight filament distortion and how best to protect children from collision forces.
