Disclosed is a method for forming an emergency lane by means of a vehicle 1, said method comprising a step of determining a minimum speed X at which it is necessary to form an emergency lane, a step of determining a longitudinal speed v of the vehicle 1, and a step of comparing the determined longitudinal speed v with the minimum speed X. The process for forming the emergency lane is activated ifthe longitudinal speed is below the minimum speed X, and deactivated if the minimum speed X is reached or exceeded. Furthermore, a system 7 for forming an emergency lane by means of a vehicle 1, a vehicle 1 having such a system, a computer program product and a computer-readable data carrier are disclosed.
