What action should be taken if an automatic warning device has been active for less than 20 seconds when approaching a grade crossing?

• A. Pass at normal speed
• B. Stop and provide warning to on-ground personnel
• C. Proceed with caution
• D. Continue without stopping

Answer: (B)

In the context of approaching a grade crossing with an active automatic warning device, it is crucial to prioritize safety and ensure that all signaling systems are functioning correctly. If the device has been active for less than 20 seconds, this suggests that a train may be approaching but has not yet been confirmed to be on the crossing. Stopping and providing a warning to on-ground personnel is the appropriate action in this scenario. This allows personnel nearby to be alerted to the potential hazard that may arise from an approaching train, ensuring they can take necessary precautions for their safety. Alerting them also ensures that they are prepared for any potential emergency that may occur, which is vital in maintaining a safe operating environment at crossings. Marking a passing action as normal speed or proceeding without caution can be risky since the brief duration of the warning device indicates that a train could soon reach the crossing. Therefore, taking immediate action to pause and communicate with on-ground personnel not only adheres to safe operational protocols but also helps prevent accidents.
