What does pressing the dead man's switch during a tram stop result in?

Explanation

Correct answer: It enables start-up of the tram.

The vigilance control system is a safety system which monitors the tram driver's consciousness and readiness to operate the vehicle. When stationary, pressing it is a necessary condition to unlock the tram's drive system. Only after this action is it possible to engage the drive and start moving, which prevents accidental moving off.
