What does the signal aspect mean when an operator may proceed on a diverging route?

The signal aspect indicating that an operator may proceed on a diverging route typically means that the operator is expected to prepare for the possibility of encountering another signal that is clear. This signals the operator to navigate a route that branches away from the main track, while also indicating that they can anticipate the following signal will permit continued movement without obstruction.

In this context, it is crucial for operators to understand the implications of proceeding on a diverging route. The requirement to expect the next signal to be clear helps prevent potential operational hazards, ensuring that the train operator is aware of the need for caution and preparedness as they transition onto a route that may have varying speed limits or signal conditions.

The other options suggest different actions that do not accurately reflect the purpose of the diverging signal aspect. For instance, stopping or operating in a confined manner does not capture the essence of diverging routes or their intended operational flow. Thus, understanding the correct meaning and expectation of this signal aspect is vital for safe and efficient train operations.
