1. A vision system for a vehicle, said vision system comprising:

  • a camera disposed at a vehicle so as to have a field of view forward of the vehicle;

    a control comprising an image processor operable to process image data captured by said camera;

    wherein said control, responsive to image processing by said image processor of image data captured by said camera, determines information on traffic signs present in the forward field of view of said camera;

    wherein said control, responsive to detection of at least one speed limit sign at a side of a road being traveled by the vehicle, determines, via image processing by said image processor of image data captured by said camera, whether the indicated speed limit is for the traffic lane being traveled by the vehicle; and

    wherein said vision system determines whether the indicated speed limit is for the traffic lane being traveled by the vehicle responsive to a determination selected from the group consisting of (i) determination that the speed limit sign is at the left side of the traffic lane being traveled by the vehicle and has an indicator representing the left side of the traffic lane and wherein the speed limit sign leaves the field of view at its left side, (ii) determination that the speed limit sign is at the right side of the traffic lane being traveled by the vehicle and has an indicator representing the right side of the traffic lane and wherein the speed limit sign leaves the field of view at its right side, and (iii) determination of a speed limit sign at both sides of the traffic lane being traveled by the vehicle with both speed limit signs indicating the same speed limit.
