Before shoving into or through a highway-rail grade crossing or pedestrian crossing, what must be true?

• A. Crossing gates are fully lowered
• B. A qualified employee is positioned at the crossing and is able to communicate with the train
• C. Either crossing gates are fully lowered or a qualified employee is at the crossing and can communicate
• D. The engineer believes it is safe

Answer: (C)

Protection at highway-rail grade crossings relies on one of two protections being in place before moving through: the crossing gates fully lowered, or a qualified employee stationed at the crossing who can communicate with the train crew to verify it’s safe to proceed. This dual requirement ensures there’s a clear, verifiable signal that the crossing is protected for vehicles and pedestrians, and that the train crew has direct confirmation before entering the crossing. Relying on the engineer’s belief alone does not provide the necessary safety guarantee, and having only one form of protection (gates or a person) without the other can leave the crossing inadequately protected in some situations.
