How should a train respond to an illuminated signal that indicates it must stop?

A train must respond to an illuminated signal indicating it must stop by coming to a complete halt. This response is critical for ensuring the safety of all passengers, crew, and those in the vicinity of the train operations. Stopping immediately is necessary because an illuminated signal generally indicates that there are conditions ahead that require the train to cease movement, such as another train occupying the tracks, maintenance work, or hazardous situations.

By adhering to this requirement, train operators prevent accidents and maintain the integrity of the rail system. Stopping immediately also allows the operator to assess the situation and follow the appropriate procedures before proceeding, ensuring a controlled and safe environment for train operations.
