The invention relates to a lane change assistant for a vehicle (1) comprising a sensor arrangement (11) for calculating information relating to lanes (50A, 50B) and other road users (S1, S2). Provided is an arithmetic and logic unit (12) for calculating movement paths for a first lane change (21, 22) and a subsequent second lane (22) to the original lane (50A). The vehicle driver can accept or initiate the calculated lane changes (21, 22). An actuator unit (15) can then execute the lane changes (21, 22) calculated by the arithmetic and logic unit (12) and initiated by the vehicle driver upon receipt of a signal from the arithmetic and logic unit (12).
