Provided are a driving assistance method and driving assistance device that make it possible for a vehicle to appropriately enter a branch road at a road section where, after a branching point is passed, one of two adjacent lanes on a main road becomes the branch road and the other becomes the main road. In the present invention, the planned travel road path of a vehicle on map data is retrieved (S1-S3), and at a road section where, after a branching point is passed, one of two adjacent lanes on a main road becomes a branch road and the other becomes the main road, when the vehicle enters therange of a prescribed distance from the branching point, if the vehicle is traveling on the lane that will become the main road after the branching point is passed, guidance is provided for switchingto the lane that will become the branch road after the branching point is passed (S4, S5). 提供在主线道路上的相邻的2条车道的一方在通过分支点后成为支线道路、另一方成为主线道路的道路区间中，车辆可适当地进入支线道路的驾驶辅助方法以及驾驶辅助装置。在地图数据上探索车辆的行驶预定道路的路径(S1～S3)，在主线道路上的相邻的2条车道的一方在通过分支点后成为支线道路
