Railroad drawbridge1 of 3
The answer
Answer: B. The manual's stop rule is between 15 and 50 feet before railroad crossings. Five to ten feet, 100 to 150 feet or exactly 25 feet are not the manual's range, which is a stop between 15 and 50 feet before the crossing, close enough to see but safely away from the tracks.

Railroad drawbridge2 of 3
The answer
Answer: B. Stop at drawbridges that do not have a signal light or traffic control attendant. Stopping only when the draw is open, only at night or only with standees would miss the situations in which a drawbridge could suddenly open, so stop whenever there is no signal light or attendant.

Railroad drawbridge3 of 3
The answer
Answer: A. Never change gears while crossing the tracks. Slowing down, opening the door and using the horn are all allowed or even needed at a crossing, whereas changing gears on the tracks could stall the engine on the rails. A missed shift or a stall with the wheels on the rails leaves the bus in the path of a train.
