2. When securing baggage and freight on a bus, which of these is one of the manual's aims?
Correct answer: Leaving every window and door usable as an exit in an emergency

3. Why does the manual tell bus drivers to always check the interior before driving?
Correct answer: People sometimes damage unattended buses, and rider safety depends on the interior being sound
Because a bus left unattended may be damaged, the driver checks handholds, railings, floor covering, signaling devices, emergency exit handles and seats before carrying riders.

4. A parent asks you to move a school bus stop to a safer-looking corner. What does the manual require before the location changes?

5. Which of these is NOT one of the manual's clues that a driver may be impaired?
Correct answer: Signaling well before each turn
The clues include weaving or drifting, leaving the road, stopping at the wrong time, a window open in the cold and sudden speed changes. Careful early signaling is not one of them.

6. Besides keeping an eye on your own vehicle, what does the manual say to use your mirrors to spot in traffic?
Correct answer: Overtaking vehicles
Regular mirror checks show you who is beside and behind you, including vehicles coming up to pass, so you know whether a quick lane change would be possible.

7. Why does the inspection section call a leaking fuel tank a hazard to other traffic as well as a fire risk?
Correct answer: Fuel on the pavement can be very slippery
A leak is a fire hazard, and fuel that reaches the road surface makes it slick for everyone else, so the tank, cap and lines are checked for leaks.

8. As riders leave your bus, what does the manual tell you to caution them about?
Correct answer: Watching their step
Riders can stumble getting on or off, so the driver reminds them to watch their step on the way out.

9. An angry driver makes gestures at you as he passes. What does the manual advise?
Correct answer: Ignore the gestures and refuse to react
Faced with an aggressive driver, you get out of the way, avoid eye contact and do not respond to gestures. Reporting the driver can wait until it is safe.

10. At dusk you are having trouble seeing other vehicles. What does that tell you about them?
Correct answer: Their drivers will have trouble seeing you, too
Poor visibility works both ways. If other vehicles are hard for you to pick out, you are hard for them to pick out, so you turn on your headlights.

11. Where should students wait for a school bus, according to the loading procedures?
Correct answer: In a designated location, facing the bus as it approaches
Students wait at a designated spot, face the bus as it arrives and board only when the driver signals them.

12. According to the inspection section, why must mirrors or other monitoring devices be in good order?
Correct answer: They let the driver see other traffic to the sides and rear, especially in blind areas
Mirrors and cameras give the driver a view along the sides and behind. Seeing other traffic, above all in blind areas, depends on them being clean, uncracked and firmly mounted.
