A vision system for a vehicle includes a camera disposed at a vehicle and viewing forwardly of the vehicle. An image processor is operable to process image data captured by the camera. Responsive at least in part to a determination that the vehicle is at a red light and the red light turns green and another vehicle in front of the vehicle moves forwardly away from the vehicle, the system may generate an alert to the driver of the vehicle. The system may include a camera that views rearwardly of the vehicle. Responsive to a determination that the vehicle is approaching an object present forwardly of the vehicle, the system may apply a vehicle brake to mitigate a collision with the determined object, and the system may reduce application of the vehicle brakes to mitigate a rear collision by a determined following vehicle.
