The distributions of injuries occurring to drivers of recent model year cars involved in highway crashes are compared with the injury rates predicted by the NCAP crash test results. Fatality rates, fatal and serious injury rates, and moderate through fatal injury rates are compared with five different crashworthiness indices derived from the crash test results. Comparisons are also made under varying crash conditions ranging from drivers wearing and not wearing safety belts in all types of crashes, to belted drivers only involved in moderate to high speed frontal impact crashes. In general, injury rates predicted by NCAP crash test results are found to bear little resemblance to those observed in real world highway crashes.
