Disclosed is an arrangement (1) and a method for mitigating a forward collision between a host vehicle (2a), having sensors (3) for monitoring a road ahead and wheel brakes (6, 7), and an oncoming vehicle (2b). The sensors (3) are utilized to estimate parameters of an oncoming vehicle (2b), such as the distance between the vehicles (2), lateral and longitudinal velocity and acceleration of the oncoming vehicle (2b), and relative longitudinal velocity between vehicles (2). The estimated parameters are utilized to predict a future path of the oncoming vehicle (2b), and host vehicle (2a) parameters to predict a future path thereof. The predicted future paths are assessed to determine if a forward collision is likely unavoidable assuming full freedom for performing avoidance manoeuvres for both vehicles (2). The wheel brakes (6, 7) are controlled to reduce a relative longitudinal velocity between the vehicles (2) at a predicted collision instant if determined that a forward collision is likely unavoidable at a determined relative longitudinal velocity above a first threshold.
