3.3 Crash/Accident Classification by Transport Vehicle Type
3.3.1 introduction: The purpose of this classification is to describe the type of transport crash/accident.
3.3.2 categories: There are five mutually exclusive categories for classification of transport accidents and crashes that are listed according to precedence. The order of precedence determines which categorization will be used when a crash or accident involves transport vehicles from multiple categories. For example, a crash involving a motor vehicle and a plane making an emergency landing would be classified as an aircraft accident. The order of precedence is as follows:
• Aircraft accident
• Watercraft accident
• Motor vehicle crash
• Railway accident
• Other-road-vehicle crash
3.3.3 basis for categories: The five categories of transport crashes/accidents listed above are based upon those used for compilation of vital statistics. Current definitions for this purpose are given in the Centers for Disease Control and Prevention, International Classification of Diseases, Tenth Revision, Clinical Modification 2017.
