If a flagger cannot provide warning in all directions, what is the speed at which the train may proceed over the crossing?

When a flagger is unable to provide adequate warning in all directions, it is essential for safety that trains reduce their speed to ensure the safety of any potential hazards that may be present. The correct speed limit of 15 MPH under these circumstances allows for better reaction times for both the train crew and any persons or vehicles near the crossing. This reduced speed reflects a balance between maintaining efficiency in rail operations while ensuring compliance with safety regulations designed to prevent accidents.

The practice of setting a speed limit in these circumstances is a critical safety measure. It ensures that if there are any unforeseen obstacles or conditions at the crossing, the train can stop in time to prevent collisions, thus protecting both the crew and the public. Reducing speed also enables train crews to have a clear view of the crossing and any warnings given, aiding in situational awareness and decision-making.
