PROBLEM TO BE SOLVED: To provide a test driving road for a vehicle, which enables a plurality of vehicles to concurrently travel without interference with one another, and which enables a driver to experience traveling on a road surface with a variable coefficient of friction. SOLUTION: This test driving road for the vehicle, which makes the driver experience the traveling of the vehicle on the road surface with the variable coefficient of friction, comprises: a plurality of circular lanes 2a-2c which are arranged at mutual intervals; a plurality of inside connecting lanes 3a-3c which constitute an inside annular lane 5 by connecting the circular lanes 2a-2c together; and a plurality of outside connecting lanes 4a and 4c which constitute an outside annular lane 6 by connecting the circular lanes 2a-2c together. The coefficient of friction of a road surface of at least one of the inside connecting lanes is set different from that of friction of road surfaces of the plurality of circular lanes 2a-2c, and the coefficient of friction of a road surface of at least one of the outside connecting lanes is set different from that of friction of road surfaces of the plurality of circular lanes 2a-2c.
