The dead-man switch is required to change between controller operation modes.

• A. Not Applicable
• B. True
• C. False
• D. Not Sure

Answer: (C)

The safety mechanism at play here is that a dead-man switch is there to stop the system immediately if the operator loses control, ensuring no motion or action continues without active oversight. It is not the mechanism that governs changing how the controller operates. Changing between manual, semi-autonomous, and autonomous modes is a deliberate transition that should be gated by explicit actions and safety preconditions to prevent unintended or unsafe switches. In practice, mode changes are managed by a mode-selection process with checks, confirmations, and proper sequencing, while the dead-man switch provides an immediate fail-safe if control is lost. Therefore, the statement is false.
