Questions (158)
1. The heavier the vehicle:
- The less important the brakes become.
- The harder the brakes need to work. ✓
- The quieter the brakes will sound.
Answer: B. The harder the brakes need to work.
The heavier the vehicle, the harder the brakes need to work. The handbook passage on vehicle weight and stopping distance says that a heavier vehicle makes the brakes do more work to stop it and absorb more heat. That directly supports the idea that extra weight puts more demand on the braking system, so the brakes must work harder. The passage does not say brakes become less important or that weight makes them quieter; it links weight to increased braking work and heat.
2. On a leaf spring, the leaves:
- May be broken.
- Are not required.
- Should not be broken. ✓
- Should shift.
Answer: C. Should not be broken.
The leaves on a leaf spring should not be broken. The handbook's inspection material says to check leaf springs for leaves that are missing, shifted, cracked, or broken. In the driving-safely section, broken leaves in a multi-leaf spring are listed as a defect, and missing or broken leaves in any leaf spring are also called a defect. A leaf spring is meant to be intact, so a broken leaf is a defect to catch during inspection, not a normal condition.
3. Test the low pressure warning signal:
- Once a month.
- Once a week.
- Twice a week.
- Before every trip. ✓
Answer: D. Before every trip.
You test the low pressure warning signal before every trip, as part of your pre-trip air brake check. The handbook puts the low pressure warning test right in the air brake inspection sequence you run through before driving: with the engine off and enough pressure that the warning is not on, you turn the electrical power on and pump the brake pedal to bleed air down, and the signal must come on before pressure falls below 55 psi. Because it is one step in that inspection routine, you check it before each trip rather than on a calendar schedule. If the signal does not work, you could lose air pressure without knowing it.
4. If you must drive in reverse at a student pick-up point, you should:
- Back up before the students board the bus.
- Back up after the students board the bus. ✓
- Back up while students direct you.
Answer: B. Back up after the students board the bus.
You should back up after the students have boarded the bus. The handbook says that if you must back up at a student pick-up point, you should pick up the students before backing and make sure all students are inside the bus before you reverse. It also says to watch for latecomers. That means the safe order is to let students board first, then back up.
5. Rollovers happen when:
- Drivers turn too quickly. ✓
- Drivers turn too slowly.
- It is raining.
Answer: A. Drivers turn too quickly.
Rollovers happen when drivers turn too quickly. The handbook says plainly that rollovers happen when you turn too fast. It also says to drive slowly around corners, ramps, and off ramps, and to keep cargo as low as possible. A related section explains that the sharper the turn, the greater the chance of a skid or rollover. Together, these passages point to fast or sharp turning as the cause, not slow turning or rain.
6. Bracing is used to:
- Make items stand taller in a trailer.
- Prevent items from moving in a trailer. ✓
- Make it easier to unload items from a trailer.
Answer: B. Prevent items from moving in a trailer.
Bracing is used to prevent items from moving in a trailer. The handbook describes bracing in the cargo-securing section. It says bracing is used to prevent movement of cargo, and it goes from the upper part of the cargo to the floor and/or walls of the cargo compartment. That matches the purpose of keeping a load from shifting during transport. The passage does not describe bracing as a way to make cargo taller or to make unloading easier; it presents bracing as a securing method.
7. What can change the height of a vehicle?
- Color
- Length
- Weight ✓
- Number of windows
Answer: C. Weight
Weight can change the height of a vehicle; the handbook notes that an empty cargo van is higher than a loaded one. The handbook says the weight of a cargo van changes its height. An empty van sits higher than a loaded one. That direct statement makes weight the factor that can change how tall the vehicle stands. The same section also warns that posted bridge heights may not be accurate because repaving or packed snow can reduce clearance, so you should not assume the posted number matches the actual opening. The answer follows from the handbook's statement about weight and vehicle height.
8. To avoid a hazard:
- You should always steer to the left.
- You may be able to drive onto the shoulder. ✓
- You should steer sharply in one direction.
Answer: B. You may be able to drive onto the shoulder.
You may be able to drive onto the shoulder when avoiding a hazard. The handbook describes leaving the road as a real option in some emergencies, saying it may be less risky than colliding with another vehicle. It notes most shoulders are strong enough to hold a large vehicle, so the shoulder can serve as an escape route. The guidance that follows assumes you have left the pavement: avoid braking hard until speed drops, keep one set of wheels on the pavement when you can, and stay on the shoulder until you stop, then signal and check mirrors before returning.
9. Which of the following types of vehicles is most prone to the “crack-the-whip" effect?
- An automobile
- A three-axle tractor
- A bobtail tractor
- A triple combination ✓
Answer: D. A triple combination
10. If turning to avoid a hazard:
- You should brake hard.
- You should not brake as it may cause the wheels to lock. ✓
- You should turn very sharply.
Answer: B. You should not brake as it may cause the wheels to lock.
