Method and operation of a tracking assistance system for multi-lane turning in a motor vehicle and motor vehicle

The method involves determining (S1) an environment data (30) which describes about multiple turning lanes. A trafficked lane is determined (S2) within a virtual lane progression based on the environment data. The virtual lane progression describes a turning area, and has two virtual lane markings. The virtual lane progression is used for providing (S4) information or assistance to a driver of a vehicle.
