An industrial vehicle implements an automatic engine stop function that automatically stops an engine installed on a vehicle body. The industrial vehicle includes an engine starting battery arranged in the vehicle body to start the engine, an operator seat arranged on the vehicle body, a seating detector adapted to detect whether or not the operator seat is vacant, and a controller adapted to disable the automatic engine stop function if the engine is started when the seating detector detects that the operator seat is vacant.
