1. A method for operating a vehicle, comprising the steps of: continuously checking during a driving operation whether an emergency situation is present in the vehicle and, when the emergency situation is detected, initiating an emergency stopping maneuver for safely parking the vehicle, signalling the emergency situation to a road user in surroundings of the vehicle, aborting the emergency stopping maneuver when a vehicle user takes over a task of driving the vehicle, and determining whether the vehicle constitutes a danger to road users in the surroundings of the vehicle after the aborting of the emergency stopping maneuver as a result of a reduced vehicle speed due to the emergency stopping maneuver; wherein the signalling of the emergency situation is automatically deactivated after the aborting of the emergency stopping maneuver when it is determined that the vehicle does not constitute the danger to road users in the surroundings of the vehicle after the aborting of the emergency stopping maneuver by determining that an ascertained duration of time between the initiating and the aborting of the emergency stopping maneuver is smaller than a predetermined time value which varies with a driving speed of the vehicle and that an ascertained reduction of the driving speed of the vehicle between the initiating and the aborting of the emergency stopping maneuver is smaller than a predetermined speed reduction value; and wherein the signalling of the emergency situation is continued after the aborting of the emergency stopping maneuver when it is determined that the vehicle does constitute the danger to road users in the surroundings of the vehicle after the aborting of the emergency stopping maneuver.
