No flagger or railroad police officer providing warning at the crossing, you must:

• A. Stop and wait for a signal
• B. Stop. Make certain that a crew member provides on-ground warning at the crossing, and do not exceed 15 MPH until the leading end operates through the crossing.
• C. Proceed slowly through crossing
• D. Call the dispatcher

Answer: (B)

If there’s no flagger or railroad police officer giving warning at a crossing, you must stop and make certain a crew member provides on-ground warning at the crossing, and you may not exceed 15 mph until the leading end of the train has cleared the crossing. This setup protects the crossing by ensuring there’s a person on site to warn road users and gives you time to observe for any vehicles or pedestrians still on the crossing before you continue. Relying on a signal or dispatcher isn’t appropriate here because there’s no protection in place at the crossing, and proceeding without on-ground warning could put traffic and crew at risk.
