An industrial truck includes a height-adjustable load-handling device, a motor, at least three wheels, at least one of the three wheels to be driven by the motor, a warning system for delivering warning signals to the surroundings, and a switching device. The warning system can be automatically activated by selecting a predetermined direction of travel of the industrial truck, and the industrial truck has at least two warning systems for delivering warning signals to the surroundings. The at least two warning systems each can be automatically activated by selecting a predetermined direction of travel of the industrial truck, and at least one of the warning systems is configured to deliver acoustic warning signals and at least one of the warning systems is configured to deliver visual warning signals. The switching device is configured to selectively activate any one of the at least two warning systems.
