| 1. An industrial vehicle having drive wheels driven by an engine, comprising:
a power transmission device through which the engine is connected to the drive wheels for transmitting output of the engine
to the drive wheels thereby to run the vehicle;
a driver detection switch for detecting whether a driver of the vehicle is seated in a driver's cabin in a driving position;
a direction indication member manipulated by the driver for indicating forward or backward movement of the vehicle; a position detection switch for detecting a manipulation position of the direction indication member;
an electromagnetic control valve for changing flow of hydraulic fluid supplied into the power transmission device; and
a controller for controlling an energizing state of the electromagnetic control valve, the controller being electrically connected
to the driver detection switch and the position detection switch, the controller outputting a signal to break energization
of the electromagnetic control valve if the driver detection switch detects that the driver is not seated, the controller
outputting another signal to energize or reenergize the electromagnetic control valve if the driver detection switch detects
that the driver is seated and then the position detection switch detects that the manipulation position of the direction indication
member is changed from a neutral position to a forward or backward position.
