Questions (197)
1. When backing a trailer, you must first turn the steering wheel:
- In the direction you want the trailer to go.
- In the direction opposite of where you want the trailer to go. ✓
- To the left.
Answer: B. In the direction opposite of where you want the trailer to go.
2. To confirm that a trailer has ABS, you can:
- Look under the trailer for wheel speed sensors coming from the back of the brakes. ✓
- Look under the hood for the ABS sticker.
- Look at the tires.
- Remove a tire and look for the ABS sensor on the axle.
Answer: A. Look under the trailer for wheel speed sensors coming from the back of the brakes.
Look under the trailer for the ABS control unit and the wheel speed sensor wiring at the rear of the brakes. The manual says that on older towed units it can be hard to know whether ABS is fitted. In that case, check underneath for the electronic control unit and the sensor wires attached at the back of the brake assemblies. The trailer's yellow warning lamp sits on the left side, but the under-vehicle parts are the check the manual describes for confirming ABS.
3. When cargo is being loaded, weight should be placed:
- As high as possible.
- As low as possible. ✓
- As close to the cab as possible.
Answer: B. As low as possible.
When you load cargo, put the weight as low as possible. The handbook warns that a high center of gravity makes a vehicle more likely to tip over, especially in curves or during a swerve. It says to arrange the load with the heaviest parts underneath the lighter parts and to keep the weight down. The combination-vehicle section makes the same point: cargo close to the ground helps reduce rollover risk. That is why placing the weight low is the safe choice.
4. Your horn should be used to:
- Tell other drivers that you are angry.
- Warn other drivers that you are near. ✓
- Frighten other drivers.
Answer: B. Warn other drivers that you are near.
Your horn should be used to warn other drivers that you are near. The handbook says your horn can let others know you are there and can help avoid a crash. It also says to use the horn when needed, while warning that unnecessary use can startle people and be dangerous. That supports using the horn as a warning of your presence. The inspection section describes the horn as a device used to warn other roadway users of your presence and avoid potential collisions.
5. When braking with ABS, you should:
- Pump the brake pedal.
- Brake normally. ✓
- Brake harder than you would with a different braking system.
Answer: B. Brake normally.
Brake normally — with ABS you brake the same way you always have. The handbook repeats this in several sections: ABS does not change the way you normally brake, and under normal brake conditions your vehicle stops as it always stopped. ABS is an add-on to your regular brakes, not a replacement, and it only kicks in when a wheel would otherwise lock up from over braking. On a tractor-trailer, the guidance is the same whether ABS is on the tractor, the trailer, or both: use only the braking force needed to stop safely and stay in control.
6. If a truck is equipped, a trailer brake hand valve can be used to:
- Add fuel to the vehicle.
- Prevent the vehicle from rolling back when being started from a stop. ✓
- Check the oil level.
- Load cargo.
Answer: B. Prevent the vehicle from rolling back when being started from a stop.
A trailer brake hand valve can be used to keep the vehicle from rolling back when you start from a stop. The handbook's starting-from-a-stop guidance says not to roll back because you may hit someone behind you. It advises using the parking brake as needed and releasing it only after enough engine power is applied. For a tractor-trailer equipped with a trailer brake hand valve, the handbook says the hand valve can be applied to keep from rolling back. That matches the bank answer.
7. If carrying a heavy load that is slowing you down, you should:
- Drive in the left lane.
- Drive in the right lane. ✓
- Drive on the shoulder.
- Keep the vehicle in second gear.
Answer: B. Drive in the right lane.
Drive in the right lane when a heavy load is slowing you down. The handbook says heavy vehicles often get tailgated when they cannot keep up with traffic, especially uphill. In that situation, if a heavy load is slowing you down, it tells you to stay in the right lane if you can. The rule is about lane choice, not about changing gears or using the shoulder. Following it keeps you in the position the handbook recommends for a slow heavy vehicle.
8. Emergency brakes:
- Are not required on trucks.
- Are only required on trailers.
- Are required on tractors. ✓
- Are optional.
Answer: C. Are required on tractors.
9. A post-trip inspection should include all of the following, except:
- Looking for articles left on the bus.
- Checking for sleeping students.
- Opening windows. ✓
Answer: C. Opening windows.
10. When asked about the vehicle's oil during the vehicle inspection test, you must be able to do all of the following, except:
- Indicate where the dipstick is located.
- Show that the oil level is within a safe operating range.
- Show that the oil level is above the refill mark.
- Show that the oil level is below the refill mark. ✓
Answer: D. Show that the oil level is below the refill mark.
You do not have to show that the oil level is below the refill mark — a level that low is a problem, not something to demonstrate. The vehicle inspection asks you to confirm that engine oil and the other fluids are at proper levels so the engine and related systems work correctly. A level in a safe operating range, at or above the refill mark, is what a proper level looks like. Oil sitting below the refill mark means the engine is low, so demonstrating that would show a fault instead of showing the check was done. That is the one item on the list that is not part of the oil check.
