A vision system for a vehicle includes a camera having a field of view in a forward direction of travel of the vehicle. The camera has a two-dimensional array of photosensing elements that includes photosensing elements arranged in a matrix array of rows and columns. A control includes an image processor that processes image data captured by the camera to detect objects of interest located within the field of view of the camera. The image processor processes captured image data to detect lane markers on the road being driven by the vehicle and located within the field of view of the camera. The vision system, responsive to processing of captured image data, automatically recognizes whether the vehicle is being driven on a road of a left hand drive road system or on a road of a right hand drive road system.
