How must signals be provided by an employee at a highway crossing?

The correct method for providing signals at a highway crossing is to give Stop Signals until the leading end of the train is through the crossing. This protocol is essential for ensuring the safety of both train operations and highway traffic. By giving Stop Signals, the employee effectively communicates to any approaching vehicles and pedestrians that they must remain stopped until it is safe to proceed. This reduces the risk of accidents and maintains a clear understanding of the train's movements.

Using Stop Signals is critical because it allows the employee to maintain control over the intersection until the train has fully cleared, thereby preventing any premature attempts by vehicles or pedestrians to pass through the crossing while the train is still present. This method aligns with the guidelines set forth by the Northeast Operating Rules Advisory Committee (NORAC) and is designed to promote safety in scenarios where trains and vehicular traffic intersect.

On the other hand, methods such as using a loud horn, hand gestures, or verbal commands do not fully address the potential risks associated with crossing traffic and the presence of a moving train. These alternatives might lack the urgency and clarity required to ensure that all parties remain aware and cautious until the train has completely passed.
