1. If an oncoming vehicle has wandered into your lane, which direction is usually best to steer to avoid a crash?
Correct answer: To your right
Move to your right when an oncoming vehicle wanders into your lane, since a driver who realizes the mistake will naturally swing back toward their own lane.

2. Which of these vehicles is always required to stop at a railroad crossing before proceeding?
Correct answer: A vehicle carrying placarded hazardous materials
Passenger-carrying buses and vehicles hauling placarded hazardous materials must stop at grade crossings even when no train is in sight.

3. You must cross the oncoming lane to complete a wide right turn. If a vehicle is coming toward you, what should you NOT do?
Correct answer: Back up to give the oncoming vehicle room
Give oncoming vehicles room to stop or pass, but do not back up to make space, because you might strike a vehicle that has moved in behind you.

4. At a passive railroad crossing that has no signals or gates, who is responsible for deciding whether to stop or go?
Correct answer: With the driver alone
A passive crossing has no lights or gates, so it is entirely up to the driver to spot the crossing, look for a train, and decide whether there is room to cross safely.

5. When making a left turn at an intersection, where should the front of your vehicle be before you begin turning?
Correct answer: At the center of the intersection
Reach the center of the intersection before starting a left turn; turning too early can cause the left side of your vehicle to strike another vehicle because of off-tracking.

6. Because a large vehicle accelerates slowly, what does it need when crossing or entering traffic?
Correct answer: A much larger gap in traffic than a car needs
Slow acceleration and the length of a large vehicle mean you need a much bigger gap in traffic than a car would, and you must be sure you can clear the road before traffic reaches you.

7. If two left-turn lanes are available, which one should a large vehicle use to make the turn?
Correct answer: The right-hand turn lane
Take the right-hand of the two turning lanes; starting in the inside lane can force you to swing right during the turn, and drivers on your left are easier to see.

8. At a crossing with double tracks, why must you "double check" before proceeding?
Correct answer: A train on one track can hide a train on the other
A train on one track can hide a second train on the other track, so look both ways and be sure no other train is coming after the first has cleared.

9. Under a move-over law, what should you do when approaching an emergency vehicle stopped on the roadside?
Correct answer: Slow down and move over to a non-adjacent lane when it is safe
Move-over laws require you to slow down and, when it is safe, change to a lane that is not next to the stopped emergency vehicle; if changing lanes is unsafe, slow down and pass with caution.

10. About how long does it take a typical tractor-trailer to clear a double railroad track?
Correct answer: More than 15 seconds
A typical tractor-trailer needs 14 seconds or more to get across one track, and over 15 seconds for a double track, so never start over unless you can fully clear it.

11. When you are stopped at a railroad crossing and a crossbuck sign is present, who has the right-of-way?
Correct answer: An approaching train, always
A crossbuck works like a yield sign, so any approaching train always has the right-of-way and you must let it pass before crossing.
