To solve a problem that, in the past, there is no other way than that an operator himself or herself directly visually check from the outside of a vehicle in order to check a containment state of work machine loaded on the vehicle, which is required to fully contain the machine when traveling, for example a vehicle for high lift works.

This working vehicle displays a state of work machine loaded on the vehicle in traveling on display means 7 on the basis of information from a work machine attitude detection means 4 for detecting attitude of the work machine. Even when a work machine power source required for driving the work machine is off, the information from the means 4 is stored in storage means 6 and the information stored in the means 6 is displayed on the means 7, and then by looking at a display on the means 7, the containment state of the work machine can be confirmed.
