What is a "dead man's handle"?
A dead man's handle is a safety feature on trains that ensures the train stops if the driver becomes unable to control the train or loses awareness. It is a lever or button that the driver must continuously hold or press while operating the train. If the driver lets go or fails to press it, the train will automatically apply the brakes and stop. This system helps prevent accidents caused by a driver becoming unresponsive or distracted. It is commonly found on older trains or in certain safety-critical situations.
Examples
The train had a dead man's handle, which automatically applied the brakes when the driver let go of the controls.
Operating the lawn mower with a dead man's handle ensures that the blades stop spinning if the operator falls.
