1. An industrial truck for driverless, autonomously-acting operation for a load to be transported, the industrial truck comprising:
a control system configured to control and to steer the industrial truck;
an evaluation unit configured to generate a signal for stopping the industrial truck; and
a detector device configured to detect obstacles located in a route, the detector device connected to the control system,
wherein the control system is configured to check a protective field and a warning field of the detector device for the presence of detected obstacles,
wherein the protective field extends under a detected obstacle,
wherein the control system is configured to automatically switch from checking the warning field to checking the protective field when the obstacle is detected in the warning field as the industrial truck traverses the route, and the control system is further configured to cause the industrial truck to continue traversing the route after detecting the obstacle when no further obstacles are detected in the protective field.
