Under what condition should the headlight be turned off according to Headlight Off Rule?

The correct condition for turning off the headlight according to the Headlight Off Rule is when the train is stopped clear of the main track. When a train is stopped in this position, it is no longer in a situation where its headlight is needed for safety or visibility to other trains or railroad personnel. This action helps to reduce unnecessary light pollution and minimizes the potential for distracting other operators or personnel on or near the tracks.

In a yard, the headlight is typically kept on to maintain visibility and safety, especially since activities such as switching and moving cars are common. When near a station, it is essential for safety, so the headlight would also remain on to signal the train's presence to passengers and other trains, especially during passenger loading and unloading. Additionally, operational rules may dictate the use of headlights at specific speeds to aid visibility and safety when the train is in motion. Thus, the stopping position of the train, rather than other conditions, best aligns with the policy regarding when to turn the headlight off.
