A safety system for a vehicle includes an imaging sensor configured to be disposed at a vehicle so as to have an exterior field of view external of the equipped vehicle. An image processor is operable to process image data captured by the imaging sensor to detect a vehicle exterior the equipped vehicle and to determine if a collision between the detected vehicle and the equipped vehicle is pending. Responsive to such determination of the pending collision, a safety feature of the vehicle is triggered before impact occurs. Responsive at least in part to processing by the image processor of captured image data to determine if a collision between the detected vehicle and the equipped vehicle is pending, the safety system takes into account if a determined impact speed of the detected vehicle relative to the equipped vehicle is above a threshold level.
