A lane shift indicating system for indicating a potential lane shift of a vehicle supporting at least partly automated steering and vehicle speed control, when the vehicle is travelling along a first driving lane of a road having a second driving lane separated from the first driving lane by one or more lane markings. The lane shift indicating system determines a driving environment of the vehicle at an initial vehicle position, and determines that the driving environment indicates that the vehicle is in a driving situation where a lane shift from the first driving lane to the second driving lane is considered appropriate, and adjusts the steering prior to a potential automated vehicle speed adjustment pertinent the determined driving situation, such that the vehicle continues its travel laterally closer to the one or more lane markings along the first driving lane, as compared to the initial vehicle position.
