[Object] A technique has been requested, which is capable of taking an effective measure against an inclined area where a required task is delayed, through a notification such as a warning.[Solution] A work vehicle includes a vehicle body, an inclination detector that detects an inclination of the vehicle body, an inclination evaluation unit that outputs travel limit information when a vehicle body inclination angle detected by the inclination detector exceeds a predetermined angle value, an own position calculation unit that calculates, based on positioning data, an own position that is a position of the work vehicle in a work field, and an inclination recording unit that records, as an inclined area, an area around a travel route to be determined based on the own position when the travel limit information is output.
