A method for determining a wet road surface condition for a vehicle driving on a road. An image exterior of the vehicle is captured by an image capture device at a first and second instance of time. Potential objects and feature objects are detected on a ground surface of the road of travel at the first instance of time and the second instance of time. A determination is made whether the ground surface includes a mirror effect reflective surface based on a triangulation technique utilizing the feature points in the captured images at the first instance of time and the second instance of time. A wet driving surface indicating signal is generated in response to the determination that the ground surface includes a mirror effect reflective surface.
