traffic crash 

Syn: motor vehicle accident (MVA). The term preferred by some purists who dislike using the word “accident,” which implies an unavoidable and unpredictable event, whereas epidemiological and other evidence shows that many traffic crashes are predictable, caused by factors that can be classified in terms of the epidemiological triad of host, agent, and environment. Host factors include risk taking; excessive speed; and impairment of judgment by alcohol, drugs, or disease. Agent factors include faulty vehicles with defective brakes or steering or other malfunction. Environmental factors include unsafe road conditions, poor grading, insufficient visibility, and the like.
