Why must a placarded vehicle stop at railroad crossings even when no train is visible?
- A.Placarded vehicles stop only when a gate is down
- B.The stop is a courtesy
- C.The stop is required for placarded vehicles (and certain others) so the driver can look and listen for a train before crossing, because a collision with hazmat can become a major incident
- D.Only empty hazmat trucks must stop
Correct answer
C. The stop is required for placarded vehicles (and certain others) so the driver can look and listen for a train before crossing, because a collision with hazmat can become a major incident
Why
The mandatory stop, generally 15 to 50 feet from the nearest rail, gives the driver a real chance to detect a train that a quick roll-through would miss. Certain vehicles, including placarded loads, school buses, and many tank vehicles, are in this always-stop category.
