A method and system operable for evaluation of an automotive vehicle forward collision threat. The presence of an oncoming vehicle in front of a host vehicle is established and a passing position of the host vehicle for the moment when the vehicles reach each other is predicted. In addition, a free passing distance for free passing of the oncoming vehicle on a first side of the host vehicle is predicted for the situation when the host vehicle is positioned in the passing position. The free passing distance is the minimum distance between the first side of the host vehicle and a road edge. A width of the oncoming vehicle is also estimated. If the free passing distance is equal to or less than a comparison value, it is decided that a forward vehicle collision threat exists. The comparison value is at least equal to the width of the oncoming vehicle.
