Abstract
This research aimed at clarifying proper management of planting demanded from a legal viewpoint. First, Article 2 of State Redress Law was set as keywords, and the judicial precedent was searched, using the internet database "law information database LEX/DB Internet". And the examples in connection with the accident which occurred since planting on a central reservation obstructs the field of view were taken up out of the searched examples. And then, the other judicial precedent was supplemented from a certain literature. Finally, four examples were summarized in the table, observing the regarded fact in the decision. As a result, some management to be taken notice of in planting on an open portion of a central reservation newly became clear. It was clarified that administrators have to restrict the height of tree planting on a central reservation to about 60~70cm in the section of the braking distance by the speed limit in the road from an edge outside a pedestrian crossing and that they have to manage tree planting based on the traffic situation of the road, grasping the situation of the visibility to the opposite lane also in other roads.
