A driver assistance system and method are disclosed which provide improved determination of possible collision objects. The system includes at least one sensor and a classification device. The threshold value of the classification device for classifying an object sensed by the at least one sensor as a possible collision object is lowered when a possible hazard situation in a region of surrounding located in front of the motor vehicle is determined based on data received from an inter-vehicular communication device. As a result, hazard situations which may not yet be determined by means of sensors belonging to conventional vehicles because of the distance or the position of the possible hazard situation with respect to the motor vehicle can be detected earlier.
