The objective of the investigation was to determine the influence of 0° rigid wall impact speed on dummy and vehicle loadings by testing three different types of vehicle at speeds of 30 km/h, 40 km/h, 45 km/h, 50 km/h and 55 km/h. The test vehicles were subcompact, compact and full-size vehicles. During the initial testing stage, a total of fifteen tests was conducted, in other words, one test for each constellation. The front seats were occupied on each occasion by two hybrid III dummies.
