If confronted with a RED/YELLOW signal, what should the operator do?

When faced with a RED/YELLOW signal, the operator is instructed to proceed with caution while remaining prepared to stop. This signal indicates a condition that requires careful attention and the possibility of changing circumstances ahead on the track.

Proceeding with caution ensures that the operator can react appropriately to any unexpected situations that may arise, such as encountering a train or other hazards on the track. The operator must be ready to bring the train to a stop if conditions dictate, which is a critical aspect of maintaining safety in rail operations. This approach emphasizes vigilance and readiness to take immediate action based on the status of the signals and surrounding environment.

In contrast, rapidly increasing speed or continuing at normal speed could compromise safety, as these actions do not allow for proper responses to any potential hazards that might arise. Therefore, the correct response to a RED/YELLOW signal is to approach with caution and readiness to stop.
