1. A method for determining a wet road surface condition for a vehicle driving on a road, the method comprising the steps of: capturing a first image exterior of the vehicle by an image capture device; capturing a second image exterior of the vehicle by the image capture device; identifying a section of the road in the first and second captured images; comparing a texture of the road in the first and second images captured by a processor; determining whether the texture of the road in the first image is different from the texture of the road in the second image; and generating a wet driving surface indicating signal in response to the determination that the texture of the road in the first image is different than the texture of the road in the second image.
