A method, apparatus and program for judging road surface conditions on which a vehicle is running. The method, apparatus and program includes the steps of: obtaining wheel speed rotational information of driving wheels of the vehicle during running from wheel speed detectors, receiving GPS radio waves to calculate positional information, and judging road surface conditions during running on the basis of a relationship between the wheel speed rotational information and the positional information. Conditions of road surfaces on which a vehicle is running can be accurately judged.
