What must a DUAL qualified employee confirm before giving verbal permission to pass a stop signal?

A DUAL qualified employee must confirm that the rails are properly lined and that the bridge is safe before giving verbal permission to pass a stop signal. This is critical because ensuring that the physical infrastructure is in proper working order directly impacts the safety of train operations.

Passing a stop signal is a serious action that can compromise safety if the route is not secure. The confirmation of proper rail alignment ensures that the train can proceed without derailing, and checking bridge safety is essential because trains must be able to traverse any bridges safely and structurally sound.

Other options, while related to operational safety, do not specifically address the immediate physical conditions required to authorize a train to safely pass the stop signal. Thus, confirming the rails and bridge safety is the most pertinent requirement in this situation.
