Answer: B — Proceed prepared to stop at the next signal until it's visible and displays a proceed indication

When departing from a clear signal after spotting cars, it is critical to proceed prepared to stop at the next signal until it becomes visible and displays a proceed indication. This approach ensures safety and compliance with railway operations protocols, as it allows for the possibility of encountering a stop or restrictive signal ahead. By maintaining a cautious speed and being prepared to stop, the conductor can safely respond to any changes in signaling that may arise, thereby minimizing the risk of accidents or collisions with other trains. It emphasizes vigilance and readiness in the dynamic environment of rail operations, as conditions can change rapidly. This practice aligns with the safety-first mindset that is essential for all railway personnel, ensuring they are always prepared for varying circumstances that may affect train movements.
