True or False: Rule 100 allows a train to operate without flag protection when fouling an adjacent track.

Rule 100 pertains to the requirements for flag protection when a train is operating in a situation where it may foul an adjacent track. The correct answer reflects the understanding that a train must always have flag protection when in such a position. This ensures safety by providing a means to alert any approaching trains on the adjacent track that there is an obstruction or potential hazard. Operating without flag protection in this scenario would pose a significant risk, as it could lead to collisions or other dangerous situations.

The key aspect of Rule 100 is its focus on maintaining safety protocols at all times, regardless of conditions such as daylight hours or the presence of other trains. The requirement for flag protection applies consistently, demonstrating a strong commitment to the safety of train operations on the LIRR network.
