Heavy trucks are involved in a significant percentage of severe traffic accidents. According to the US statistics, heavy trucks are overrepresented in traffic fatalities; they were involved in 12 % of all the fatalities reported in 2004 but accounted for only 7% of total vehicle miles travelled (National Highway Traffic Safety Administration; NHTSA, 2004). In addition to personal injuries and fatalities, heavy truck accidents can result in environmental hazards like spill of cargo. All of these accidents can result in severe financial consequences. There is therefore a strong motivation, from both vehicle safety and financial aspects, to study how these accidents can be prevented. An analysis of heavy truck accidents based on the Large Truck Crash Causation Study database with respect to loss of control is presented. Heavy truck accidents were analysed with regard to the accident type, loss of control type, critical manoeuvre, vehicle combination type and different road characteristics. Three critical manoeuvres were identified as the most common manoeuvres causing loss of control. Based on the accident analysis results, relevant existing test manoeuvres were adapted for trucks and compared to determine a suitable test for evaluation of yaw stability of heavy trucks on a dry and level road. The comparison was conducted on a 5DOF tractor-trailer model in Matlab-Simulink.
