Abstract
Legal term "Risk of Collision" of INTERNATIONAL REGULATIONS FOR PREVENTING COLLISIONS AT SEA in 1972 and LAW FOR PREVENTING COLLISION AT SEA (law No. 62 of 1977) is important for law application on conduct. But the difficulty of legal definition of the term and developing the moment at which these regulations and law become applicable has been recognized by seamen and legal experts. Furthermore positive researches on the occurrence opportunity of "Risk of Collision", especially the distance from give-way vessel to stand-on vessel, are few and far between. In this paper, we discussed the conception of "Risk of Collision" and the time for law application through the analysis of judgments on marine accidents inquiry agencies.
