Crashworthiness is the relative safety of vehicles in preventing injury and/or severe injury in crashes. Crashworthiness ratings for 1982-90 model vehicles were developed based on crash data from Victoria and New South Wales. Crashworthiness was measured by a combination of injury severity of injured drivers) and injury risk (of drivers involved in crashes). Injury severity was based on over 22,000 drivers injured in crashes in the two States. Injury risk was based on over 70,000 drivers involved in crashes in New South Wales where a vehicle was towed away. The results measure the crashworthiness of the makes and models of vehicles, free from the effects of driver sex and speed zone differences between models. The analysis suggested that the different results were predominantly due to vehicle factors alone. The results are reliable in indicating the crashworthiness of the vehicles specified to the extent indicated by the error limits, and can be used to make reliable comparisons of the crashworthiness of pairs of models when the error limits do not overlap. However the results and conclusions are based on a number of assumptions and warrant a number of qualifications which should be noted.
