An unmanned conveyance vehicle includes a monitoring section which includes, as monitoring regions for detecting obstacles, a first monitoring region and a second monitoring region which is capable of detecting obstacles that are more distant than the first monitoring region, and a light emitting section which emits light in the first monitoring region, in which when an obstacle is detected within the first monitoring region, a vehicle is caused to perform an emergency stop. Ordinarily, when the unmanned conveyance vehicle stops the light emission of the light emitting section and detects an obstacle within the second monitoring region, the unmanned conveyance vehicle causes the light emitting section to emit light. Accordingly, when an operator enters the second monitoring region, the operator is capable of recognizing a distance at which, when reached by the unmanned conveyance vehicle, the unmanned conveyance vehicle will perform the emergency stop.
