What should be the train operator’s action if a signal is imperfectly displayed?

When encountering an imperfectly displayed signal, the train operator must treat it as the most restrictive indication. This protocol is in place to ensure safety, as an imperfect signal could indicate a potential hazard or a need to stop. By interpreting the signal as the most restrictive, the operator takes a conservative approach, prioritizing the safety of passengers, crew, and the train itself. This action prevents the risk of proceeding where a clearer indication might have mandated an immediate stop or reduction in speed.

In situations where signals are compromised in their clarity, opting to treat them conservatively helps manage any unforeseen dangers that may not be immediately visible. Operators are trained to err on the side of caution, adhering to safety protocols that underscore the importance of caution in the event of uncertainties regarding signals.
