Abstract: Disclosed is a method for a vehicle transmitting a signal in a wireless communication system. The method may comprise: receiving information on a road environment; driving a vehicle along a selected path on the basis of the information on the road environment; and, on the basis of satisfying a predetermined condition, transmitting a message for reserving a lane change to a specific lane among at least one lane included in the path. In addition, the message may include information on a virtual vehicle corresponding to the vehicle when in the specific lane. In addition, whether or not the predetermined condition is satisfied may be determined on the basis of: i) the right of way of the vehicle with respect to the lane changing; or ii) a back-off counter.
