Method for transversely guiding motor vehicle on road, and motor vehicle

The invention relates to a method for transversely guiding a motor vehicle on a road, in which a lane marking associated with the driver side of the motor vehicle is associated with a lane type on the basis of sensor data representing the surroundings of the motor vehicle, wherein the lane type characterizes whether the lane marker is assigned to an own lane on which the motor vehicle is to be guided or to an adjacent lane adjacent to the own lane; assigning a lane marking associated with the driver side of the motor vehicle to a lane type on the basis of the cluster data received from the further vehicle; if the lane type ascertained from the sensor data is different from the lane type ascertained from the cluster data, determining the lane type assigned to the lane marker as the lane type ascertained from the cluster data; the motor vehicle is controlled transversely by means of the control device in an assisted manner as a function of the determined lane type of the lane marking associated with the driver
