3. At which railroad crossings does the manual tell you to be especially alert?

4. Besides stops that are otherwise required by law, when does the manual say a full stop at a grade crossing is required?
Correct answer: When state or federal regulations require a stop because of the kind of cargo carried
The manual gives two triggers for a required full stop: the cargo's nature makes it mandatory under state or federal rules, or the stop is otherwise required by law.

5. On the road test you stop at a stop line for a red light on a slight grade. What must your vehicle not do while stopped?
Correct answer: Roll forward or backward
At an intersection stop, the vehicle must come to a complete stop behind the line, keep a safe gap from any vehicle ahead, and must not roll in either direction.

6. An enforcement official at a railroad crossing signals you to wait, but you see no train and drive through in your CMV. How do the CDL rules treat this?
Correct answer: As a grade crossing violation that costs the CDL for at least 60 days on a first conviction
Disobeying a traffic control device or an enforcement official at a crossing is one of the six listed offenses. A first conviction in a CMV means at least 60 days without the CDL.

7. At an intersection with two left-turn lanes, the manual tells large vehicles to use the right-hand turn lane. What visibility benefit does it mention?
Correct answer: Drivers on your left are easier to see
Starting from the inside lane may force you to swing right to complete the turn. From the right-hand turn lane, the manual notes, drivers to your left can be seen more readily.

8. You drive a dry van that is not required to stop at every railroad crossing. To avoid a grade-crossing violation, what must you still do as you approach one?
Correct answer: Slow down, check that the tracks are clear, and stop before the crossing if they are not
For drivers who need not always stop, two of the listed offenses are failing to slow and check for an approaching train, and failing to stop before the crossing when the tracks are not clear.

9. According to the manual, which two characteristics of large vehicles cause them to hit other vehicles or objects during turns?
Correct answer: Wide turning and off-tracking
The manual says the space around a truck or bus matters in turns because wide turning and off-tracking can bring the vehicle into contact with other vehicles or objects.

10. You approach an emergency vehicle stopped on the roadside. Which response is NOT what the manual's move-over guidance describes?
Correct answer: Stopping in your lane until the emergency vehicle leaves
The guidance is to slow, yield by moving to a lane that is not beside the emergency vehicle if conditions allow, and otherwise slow down and continue with caution. It does not call for stopping in the travel lane.

11. Why does the manual say you should never try to race a train to a crossing?
Correct answer: An approaching train's speed is extremely hard to judge
The manual says it is extremely difficult to judge how fast an approaching train is moving, or how far away it is, so trying to beat it across is never worth attempting.

12. If you stop to help at an accident, the manual says to park away from it. What reason does it give?
Correct answer: Emergency vehicles will need the area right around the accident
The space immediately around the accident has to stay open for emergency vehicles, so a driver stopping to help should leave it clear and park at a distance.
