A method and device for warning a following vehicle on a defined roadway section about an obstacle. Ego trajectories of ego vehicles moving on the roadway section are captured in a first time interval and a first swarm trajectory is formed therefrom and stored with a first time stamp. A second swarm trajectory is formed from ego trajectories of ego vehicles moving on the roadway section in a second time interval, the second time interval being offset in time from the first time interval. The second swarm trajectory is stored with a second time stamp. A difference between the first and second trajectories and an associated difference magnitude are formed. If this difference magnitude is greater than a predetermined threshold, an obstacle is recognized as being present on the roadway section and a warning signal is output to a following vehicle.
