If a crossing warning devices fail to activate, what is the first action required?

• A. Proceed slowly and watch for vehicles
• B. Stop, protect the crossing, and notify the dispatcher for guidance
• C. Dispatch maintenance to fix devices while you continue
• D. Ignore until traffic passes

Answer: (B)

When crossing protection devices aren’t working, the first step is to stop before the crossing, protect the crossing, and notify the dispatcher for guidance. This approach places safety first because you can’t rely on the warning signals to alert road traffic or other trains. Stopping gives you time to establish protection—such as signaling or posting as required by your procedures—to ensure no vehicle or pedestrian enters the crossing while the warning system is down. Notifying the dispatcher then allows you to get immediate instructions and arrange the necessary maintenance or traffic coordination.

Rushing through, continuing slowly with no clear protection plan, or ignoring the situation would risk a collision since the failed devices remove the primary warning mechanism.
