PROBLEM TO BE SOLVED: To provide a traveling vehicle capable of enhancing unmanned traveling property at environment including a water reservoir and also preventing damage or the like of a vehicle body without making a sensor system to a complicated one. SOLUTION: The traveling vehicle includes the vehicle body 2; a wheel 4; a control part 5 provided with a non-contact type sensor 3 for measuring the road surface condition in an advancement direction, decelerating the vehicle body 2 and advancing it to an indefinite water reservoir portion M at a slight speed at the stage that the indefinite water reservoir portion M where existence of water is presumed is captured; a contact sensor 6 for detecting whether or not a bottom portion of the vehicle body is ground-contacted with an edge portion Ma at the stage that a front part wheel 4 of the vehicle body 2 intrudes to the indefinite water reservoir portion M; an escaping mechanism 10 for escaping the vehicle body 2 from the indefinite water reservoir portion M by instruction from the control part 5 at the stage that the bottom portion of the vehicle body 2 is ground-contacted with the edge portion Ma; and a water detection sensor 7 for detecting existence of moisture at the indefinite water reservoir portion M and promoting retreating of the vehicle body 2 from the indefinite water reservoir portion M to the control part 5 at the stage that the front part wheel 4 of the vehicle body 2 is sunk in water at the indefinite water reservoir portion 4.
