Updated Evaluation of Size and Mass Effects in Front-to-Front Crashes Involving Light Vehicles 2009-01-0375

Studies used 1981–2006 FARS and state crash data to examine the relative importance of vehicular, driver, and environmental factors in influencing odds of driver fatality in two-vehicle (car-to-car, light truck-to-car, and light truck-to-light truck) frontal crashes for 1981–2003 model-year vehicles. It was found that all vehicle factors, including vehicle frontal stiffness, have a second order effect compared to vehicle weight. Most of the driver factors included were found to be highly significant. Assumptions and methodology used by other vehicle size/weight safety studies were also evaluated. Results show trends similar to those of other key studies, with one notable exception.
