• an evaluation device for determining a distance and a width of the bottleneck as well as a distance, a width, and a current driving speed of the oncoming vehicle;
• a prediction device for predicting an expected trajectory for the vehicle and the oncoming vehicle, and for ascertaining an expected meeting point of the vehicle and the oncoming vehicle;
• a control device for analyzing the predicted traffic situation and for activating a safety device in the event that the expected meeting point of the vehicle and the oncoming vehicle lies in a region of the bottleneck, wherein an activation instant of the safety device is ascertained as a function of a current traffic situation.
