What should the tram driver do, seeing the signalling device indicating a change in the position of the rail switch to the right?
Explanation
Correct answer: Take a look at the switch points to make sure it is positioned in the right direction.
The signal indicating the position of the points is only an auxiliary device and is subject to failure. Therefore, the tram driver is under an absolute obligation to slow down and visually verify that the point blades are actually set in the desired direction. This is a key safety principle which prevents derailment or entering the wrong track.
