The Ministry of Transport (MOT) is carrying out a motor vehicle accident investigation every year for the accurate determination of the actual status of motor vehicle accidents, clarification of the relationship between motor vehicle construction/equipment and human injuries, reinforcement of motor vehicle safety standards (Safety Regulations for Road Vehicles) and the promotion of technical evaluation of individual items of existing standards. Each investigation consists of case studies aimed at the in-depth study of specific details of accidents, conditions of accidents occurred in investigation areas, and statistic survey to find the proper position of each accident subject to investigation. Roughly 100 cases of accidents are studied and 4,500 cases are subject to the statistic survey for the duration of four months in every year. Investigation data are processed into computer files to allow a proper analysis, according to the purpose of study at any time as called for.
