Home › CDL Practice Tests › Combination Vehicles Questions › Question 188
Which vehicles are generally required to stop at every railroad crossing, no matter what?
- A.Only empty tankers returning to the terminal
- B.Vehicles carrying certain hazardous materials (placarded loads) and passenger-carrying vehicles such as buses
- C.All combination vehicles, loaded or not, in every state
- D.Only vehicles with more than three axles
Correct answer
B. Vehicles carrying certain hazardous materials (placarded loads) and passenger-carrying vehicles such as buses
Why
Federal and state rules single out placarded hazmat loads and buses for mandatory stops because of the consequences of a collision. Other drivers stop when signals, sight distance, or conditions require it, but these classes always stop.
