1. What does the manual report about when students are most likely to be killed in school bus travel?
Correct answer: While getting on or off the bus
Each year more students die boarding or leaving a school bus than die riding inside one, which is why loading and unloading procedures matter so much.

2. Late at night a drunk rider is disrupting your bus, and you are on a dark stretch far from anything. What does the manual say about putting the rider off?
Correct answer: Don't discharge the rider where it would be unsafe; wait for the next scheduled stop, or a lighted place where other people are around
You are responsible for a disruptive rider's safety as well as everyone else's. The manual says not to let such riders off where they would be unsafe, and many carriers have their own guidelines.

3. You have to keep driving in fog. What does the manual say about passing other vehicles?
Correct answer: Avoid passing
The fog guidance is not to drive at all if you can help it. When you must, the list of precautions includes staying behind other vehicles instead of passing them.

4. A student's offense is so serious that you feel you can't drive the school bus safely. What does the manual tell you to do?
Correct answer: Have a school administrator or a police officer come to take the student off the bus
When the bus can't be driven safely because of the offense, the driver asks for an administrator from the school, or the police, to remove the student, following state or local procedures for requesting help.

5. While students board at a school bus stop, what does the manual say to do about their number?
Correct answer: Count the students at the stop and make sure all of them board
Drivers count the students waiting and confirm every one gets on, learn their names where possible, and ask the others about anyone who is missing.

6. After an accident, compressed gas is escaping from your truck. Besides warning others of the danger, whom may you allow to get close?
Correct answer: Only people who are working to remove the hazard or clear the wreckage
With leaking compressed gas, the driver warns others and lets nobody near except the people who are dealing with the hazard or the wreckage.

7. You see what looks like human trafficking at a truck stop. Why does the manual warn against approaching the traffickers yourself?
Correct answer: It is dangerous for you and the victims, and it could cause problems in prosecuting the traffickers later
The warning says to call the hotline and let the FBI and local police handle it. Confronting traffickers puts you and the victims in danger and can create problems when the traffickers are eventually prosecuted.

8. According to the trafficking information at the front of the manual, how is a minor engaged in commercial sex regarded?
Correct answer: As a victim of human trafficking
The material states flatly that a minor involved in commercial sex is a trafficking victim, with no need to show force, fraud or coercion.

9. When you unload at the school, what should students do until you tell them to exit?
Correct answer: Remain seated

10. A student's behavior on your school bus is bad enough that you want the student off the bus. Where may you put the student off?
Correct answer: Only at school or at the student's designated bus stop
The manual forbids putting a student off anywhere other than the school or the stop assigned to that student, however serious the misbehavior.

11. How should students board a school bus, according to the loading procedures?
Correct answer: Slowly, in single file, using the handrail

12. Passing cars make one side of a school bus a danger area at all times. Which side?
Correct answer: The left side
The danger zones reach as far as 30 feet ahead of the bus and 10 feet out from each side and the rear, and the manual adds that the bus's left side is treated as dangerous at all times because cars pass there.
